Question 1

Consider the following activities:
1. Research and Development
2. Insurance
3. Wholesale trading
4. Telecommunication

How many of the above are classified as Tertiary Activities?

Accepted Answer

Only three. Statement 1 is incorrect. Research and Development is classified as a Quaternary Activity, which is distinct from Tertiary Activities. Quaternary activities are centered on information, research, and development. Statements 2, 3, and 4 are correct. Insurance is a Financial Service, Wholesale trading falls under Trade, and Telecommunication is a form of Communication. All of these—Trade, Communication, and Services (including Financial)—are explicitly categorized as Tertiary Activities. Therefore, only three of the listed activities are Tertiary Activities.

Question 2

Consider the following statements:
Statement I: In a developed economy, the majority of workers are employed in tertiary activities.
Statement II: The expertise in tertiary activities relies more heavily on the specialised skills, experience, and knowledge of workers rather than on production techniques and machinery.

Which one of the following is correct in respect of the above statements?

Accepted Answer

Both Statement I and Statement II are correct, and Statement II is the correct explanation for Statement I.. Both statements are correct. Statement I accurately reflects the employment structure of a developed economy. Statement II correctly defines the fundamental difference between tertiary and secondary activities. Statement II provides a valid explanation for Statement I because the shift towards a developed, service-based economy is characterized by an increased demand for professional skills, specialized knowledge, and expertise (health, education, finance), which are the hallmarks of the tertiary sector. This demand for skilled manpower, as described in Statement II, drives the employment shift noted in Statement I.

Question 3

Consider the following statements regarding the service sector:
1. In the initial stages of economic development, the majority of workers are employed in the tertiary sector.
2. The output of tertiary activities is indirectly measured in terms of wages and salaries rather than tangible goods.
3. The expertise in tertiary activities relies more heavily on production techniques and factory processes than on the specialised skills of the workers.

How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is incorrect. During the initial stages of economic development, the primary sector employs the largest proportion of the workforce, not the tertiary sector. Statement 2 is correct. Tertiary activities produce services, not tangible goods, and their output is measured indirectly through metrics like wages and salaries. Statement 3 is incorrect. The defining characteristic of tertiary activities is the reliance on specialized human skills, knowledge, and experience, rather than on machinery and factory processes which are characteristic of secondary activities. Therefore, only one statement is correct.

Question 4

Consider the following economic activities:
1. Banking
2. Audio-visual media
3. Retail trading
4. Research and Development

How many of the above are classified as Tertiary Activities?

Accepted Answer

Only three. Item 1 is correct; Banking is a financial service, which falls under Tertiary Activities. Item 2 is correct; Audio-visual media is a form of communication, classified under Tertiary Activities. Item 3 is correct; Retail trading is a key component of the trade sector, which is a Tertiary Activity. Item 4 is incorrect; Research and Development is classified as a Quaternary Activity, a more specialized subset of the service sector distinct from Tertiary Activities. Therefore, only three of the activities are classified as Tertiary.

Question 5

Consider the following rows, which match a specific activity to its classification within the service sector:
Row 1: Category - Transport; Sub-category - Audio-visual
Row 2: Category - Services; Sub-category - Real estate
Row 3: Category - Trade; Sub-category - Retail trading

In how many of the above rows is the sub-category correctly matched with its main category?

Accepted Answer

Only two rows. Row 1 is incorrectly matched. Audio-visual activities are a component of the 'Communication' sector, not the 'Transport' sector. Row 2 is correctly matched, as 'Real estate' is classified as a type of 'Service' within tertiary activities. Row 3 is also correctly matched because 'Retail trading' is a primary sub-category of 'Trade'. Therefore, only two of the rows are correctly matched.

Question 6

Consider the following statements regarding different sectors of the economy:
1. Quinary activities, often referred to as 'gold collar' professions, are a specialized subdivision of the Quaternary sector.
2. Personnel working in university classrooms, hospitals, and software development firms are primarily categorized under Quaternary activities.
3. Quaternary activities, unlike resource-based primary activities, are not necessarily localized by market and are capable of being outsourced.
How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is incorrect. Quinary activities are described as another subdivision of the tertiary sector, representing the highest level of decision-makers, not a subdivision of the Quaternary sector. Statement 2 is correct. The category of Quaternary services includes personnel working in 'university classrooms, hospitals and doctors’ offices,' and 'software developers.' Statement 3 is correct. Quaternary activities are not tied to resources or localized by market, and like some tertiary functions, they can be outsourced.

Question 7

Consider the following rows matching economic activities with their characteristics or examples:
Row 1: Quaternary Activity : Senior Business Executive
Row 2: Quinary Activity : Focus on the creation and interpretation of new ideas
Row 3: Knowledge Sector : Employs over half of all workers in developing economies
In how many of the above rows is the given information correctly matched?

Accepted Answer

Only one row. Row 1 is incorrectly matched. Senior business executives are classified under Quinary activities, which involve the highest level of decision-making. Row 2 is correctly matched. Quinary activities are defined as services that focus on the 'creation, re-arrangement and interpretation of new and existing ideas'. Row 3 is incorrectly matched. The 'Knowledge Sector' accounts for over half of all workers in developed economies, not developing ones.

Question 8

Consider the following statements regarding Quaternary activities: 1. Personnel working in elementary schools, university classrooms, and hospitals are classified under this category. 2. These activities are fundamentally dependent on the availability of local natural resources and are significantly affected by the environment. 3. They represent a subdivision of the tertiary sector and, like some tertiary functions, can be outsourced. How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. Personnel in educational institutions like elementary schools and universities, as well as in healthcare settings like hospitals and doctors' offices, are part of the knowledge-oriented service sector, which falls under Quaternary activities. Statement 2 is incorrect. This is a factual inversion. Quaternary activities are characterized by their locational independence; they are not tied to resources, are not significantly affected by the environment, and are not necessarily localized by market. Statement 3 is correct. Quaternary activities are an advanced form of services and are considered a subdivision of the tertiary sector. A key characteristic they share with some tertiary functions is the ability to be outsourced. Therefore, only two statements are correct.

Question 9

Consider the following rows regarding economic activities: Row 1: Quinary Activities - Focus on the creation, re-arrangement, and interpretation of new and existing ideas. Row 2: 'Gold Collar' Professions - Represent the skills of senior business executives, government officials, and research scientists. Row 3: Quaternary Activities - Fundamentally localized by market demand and environmental conditions. In how many of the above rows is the given information correctly matched?

Accepted Answer

Only two rows. Row 1 is correctly matched. Quinary activities are defined by their focus on high-level conceptual work, which includes the creation, re-arrangement, and interpretation of ideas, data, and new technologies. Row 2 is correctly matched. The term 'gold collar' professions accurately describes the nature of quinary activities, which involve the special and highly paid skills of senior decision-makers like business executives, government officials, and research scientists. Row 3 is incorrectly matched. Quaternary activities are distinctly not localized by market or environment. As information-based services, they are not tied to specific resources or geographical locations, which is the very reason they can be outsourced. The statement presents the opposite characteristic. Therefore, only two rows are correctly matched.

Question 10

Consider the following professions: 1. Senior business executives making strategic decisions. 2. Statisticians involved in data collection and production. 3. Government officials formulating national policies. 4. Software developers creating new applications. How many of the above are typically classified under Quinary activities?

Accepted Answer

Only two. Statement 1 is correct. Quinary activities are performed by the highest level of decision-makers or policymakers. Senior business executives fit this description and are considered 'gold collar' professions. Statement 2 is incorrect. Statisticians are involved in the collection and production of information, which is a characteristic of Quaternary activities. Statement 3 is correct. Government officials engaged in formulating policy are classified under quinary activities, which focus on the creation, re-arrangement, and interpretation of ideas. Statement 4 is incorrect. Software developers are part of the information-based service sector, which is classified as a Quaternary activity centered on specialized knowledge and technical skills. Therefore, only two of the listed professions are classified as Quinary.

Question 11

Consider the following statements: Statement I: Quaternary activities, unlike many primary sector activities, are not necessarily tied to specific resources or localized by markets. Statement II: The Quaternary sector is fundamentally knowledge-oriented, involving the collection, production, and dissemination of information which can be transmitted globally. Which one of the following is correct in respect of the above statements?

Accepted Answer

Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I.. Statement I is correct. Quaternary activities can be outsourced and are not tied to resources, affected by the environment, or necessarily localized by market. Statement II is also correct. This sector is defined by its focus on information and knowledge, involving activities like research, development, and specialized technical skills. Statement II provides the correct causal explanation for Statement I. Because the primary 'raw material' of the quaternary sector is information and knowledge, which is highly portable and not geographically fixed like a mineral deposit (primary sector), these activities are not bound to a specific location and can be easily outsourced.

Question 12

Consider the following statements regarding different types of economic activities and markets: 1. Periodic markets are typically found in urban centers where they cater to specialized demands on specific days. 2. Urban marketing centers are characterized by the provision of manufactured goods and professional services like those from lawyers and physicians. 3. The services of a veterinarian are classified as a quinary activity. How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is incorrect. Periodic markets are characteristic of rural areas where there are no regular markets, not urban centers. This is a spatial swap. Statement 2 is correct. Urban marketing centers are described as offering specialized services, manufactured goods, and professional services from individuals such as lawyers and physicians. Statement 3 is incorrect. The services of a veterinarian are listed as an example of professional services available in urban centers, which fall under the broad category of tertiary activities, not the high-level decision-making quinary sector. Therefore, only one statement is correct.

Question 13

Consider the following statements regarding different forms of trade and commerce:
1. Rural marketing centers are rudimentary trading hubs that primarily focus on retail trading through mandis.
2. Departmental stores operate by delegating purchasing and sales authority to heads of different sections within a single large establishment.
3. Wholesale trading is characterized by bulk business conducted through intermediary merchants, though some large retail stores can bypass this and buy directly from manufacturers.
How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is incorrect. 'Mandis' function as wholesale markets, not retail centers. The statement incorrectly associates mandis with retail trading, whereas rural marketing centers contain both wholesale (mandis) and separate retailing areas. Statement 2 is correct. The defining characteristic of a departmental store is the delegation of responsibility and authority for purchasing and sales oversight to the heads of different departments within a single large store. Statement 3 is correct. Wholesale trading is conducted in bulk through intermediary merchants. However, some large retail entities, like chain stores, have the capacity to bypass these intermediaries and purchase directly from manufacturers. Therefore, only two statements are correct.

Question 14

Consider the following statements:
Statement I: Chain stores are often able to achieve significant economic advantages and operational efficiencies compared to other retail formats.
Statement II: They can purchase merchandise most economically, sometimes directing manufacturers to produce goods to their specific requirements, and can apply successful experiments from one store across the entire network.
Which one of the following is correct in respect of the above statements?

Accepted Answer

Both Statement I and Statement II are correct and Statement II is the correct explanation for Statement I.. Statement I posits that chain stores possess significant economic and operational advantages. Statement II elaborates on the specific mechanisms that create these advantages. It points to their ability to achieve economies of scale in purchasing ('purchase merchandise most economically'), control product specifications by dealing directly with manufacturers, and innovate efficiently by testing strategies in a single store before a network-wide rollout. Because these operational capabilities directly result in the economic advantages mentioned in Statement I, Statement II serves as the correct explanation for Statement I.

Question 15

Consider the following statements regarding rural marketing centers:
1. They are classified as fully developed urban centers with a wide range of specialized services.
2. They serve a dual function as both local collecting points for agricultural produce and distributing points for other goods.
3. These centers are characterized by the presence of mandis (wholesale markets) but typically lack areas for retail trading.
How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is incorrect. Rural marketing centers are described as 'quasi-urban' and 'rudimentary,' with 'less developed personal and professional services,' not as fully developed urban centers. Statement 2 is correct. They function as 'local collecting and distributing points,' fulfilling this dual role for their surrounding rural areas. Statement 3 is incorrect. These centers have both 'mandis (wholesale markets) and retailing areas,' indicating the presence of both forms of trade, not the exclusion of retail. Therefore, only one statement is correct.

Question 16

Consider the following rows, which match a type of trading or retail format with its key characteristic:
Row 1: Departmental Store : Delegates purchasing and sales authority to heads of different sections within the store.
Row 2: Chain Store : Was the first large-scale innovation in retailing, operating on a cooperative basis.
Row 3: Wholesale Trading : Involves the direct sale of goods from fixed establishments to the final consumer.
In how many of the above rows is the given information correctly matched?

Accepted Answer

Only one row. Row 1 is correctly matched. Departmental stores are defined by their structure of delegating 'responsibility and authority to departmental heads for purchasing of commodities and for overseeing the sale in different sections of the stores.' Row 2 is incorrectly matched. The characteristic described ('first of the large-scale innovations in retailing') belongs to Consumer cooperatives, not Chain stores. Row 3 is incorrectly matched. The characteristic described ('direct sale of goods... to the final consumer') defines Retail trading, not Wholesale trading, which constitutes bulk business through intermediary merchants. Therefore, only one row is correctly matched.

Question 17

Consider the following pairs:
Row 1: Consumer Cooperative - The first of the large-scale innovations in retailing.
Row 2: Non-store Retail - Includes activities like street peddling, mail-order, and internet sales.
Row 3: Wholesaler Capital - Retailers operate largely on this by extending credit to wholesalers.
In how many of the above rows is the information correctly matched?

Accepted Answer

Only two rows. Row 1 is correctly matched. The text states, 'Consumer cooperatives were the first of the large-scale innovations in retailing.' Row 2 is correctly matched. The text lists 'street peddling, handcarts, trucks, door-to-door sales, mail-order, telephone sales, automatic vending machines, and internet sales' as examples of non-store retail trading. Row 3 is incorrectly matched. It contains a causality reversal. The text states that 'Wholesalers often extend credit to retail stores to such an extent that the retailer operates very largely on the wholesaler’s capital.' The row incorrectly suggests that retailers extend credit to wholesalers. Therefore, only two rows are correctly matched.

Question 18

Consider the following rows regarding the concepts of transport networks and measurement:

Row 1: Isochrone lines - Lines drawn on a map to join places equal in terms of the cost of travel.
Row 2: Node - The meeting point of two or more routes, a point of origin, or a point of destination.
Row 3: Link - Any sizeable town along a route that serves as a point of origin or destination.

In how many of the above rows is the given information correctly matched?

Accepted Answer

Only one row. Statement-by-statement analysis: Row 1 is incorrectly matched. The text defines Isochrone lines as joining places equal in terms of the 'time taken to reach them', not the 'cost of travel'. This is a terminology swap trap. Row 2 is correctly matched. The text defines a node as 'the meeting point of two or more routes, a point of origin, a point of destination or any sizeable town along a route'. The definition provided in the row is a subset of this and is accurate. Row 3 is incorrectly matched. The text defines a link as 'Every road that joins two nodes'. The definition provided in the row describes a node, not a link. Therefore, only one row (Row 2) is correctly matched.

Question 19

Consider the following statements regarding concepts in transport geography:

1. Isochrone lines are drawn on a map to connect places that are equidistant in terms of route length, or km distance.
2. In a transport network, a 'link' is defined as the meeting point of two or more routes or any sizeable town along a route.
3. The selection of a particular mode of transport is determined more by the time or cost distance than by the actual route length.

How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is incorrect. The text specifies that isochrone lines are drawn on a map 'to join places equal in terms of the time taken to reach them', which refers to time distance, not km distance or route length. Statement 2 is incorrect. The text defines a 'node' as 'the meeting point of two or more routes, a point of origin, a point of destination or any sizeable town along a route'. A 'link' is defined as 'Every road that joins two nodes'. The statement incorrectly swaps the definition of a node with a link. Statement 3 is correct. The text explicitly states, 'In selecting the mode of transport, distance, in terms of time or cost, is the determining factor.' Therefore, only one statement is correct.

Question 20

Consider the following statements:

Statement I: In the contemporary era, communication services are not wholly dependent on the efficiency of the transport network.
Statement II: The development of technologies like mobile telephony and satellites has enabled the transmission of messages to be independent of physical transport.
Statement III: The persistence of large volumes of mail being handled by post offices is primarily due to the cheapness of these older systems.

Which of the following is correct in respect of the above statements?

Accepted Answer

All three statements are correct, and Statement II is the correct explanation for Statement I.. Statement I is a correct assertion based on the text. It notes that while transport networks were historically essential for communication, this is no longer always the case. Statement II is also correct and provides the direct cause for Statement I. The text states, 'Certain developments, such as mobile telephony and satellites, have made communications independent of transport.' This directly explains why communication is no longer wholly dependent on transport. Statement III is also a correct assertion, as the text mentions that 'very large volumes of mail continue to be handled by post offices' because of the 'cheapness of the older systems'. However, Statement III explains the persistence of an older system; it does not explain the modern independence of communication from transport described in Statement I. Therefore, all three statements are correct, and Statement II provides the correct explanation for Statement I.

Question 21

Consider the following statements:

Statement I: In the contemporary era, the dissemination of information and ideas is not solely dependent on the efficiency of physical transport networks.
Statement II: The development and proliferation of mobile telephony and satellite communication have enabled direct and instantaneous transmission of messages, making communication independent of transport.

Which one of the following is correct in respect of the above statements?

Accepted Answer

Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I.. Statement I is correct. The text explicitly states that certain developments, such as mobile telephony and satellites, have made communications independent of transport. Statement II is also correct. It provides the specific examples (mobile telephony, satellites) and the mechanism (direct and instantaneous transmission) that have led to this independence. Because Statement II provides the direct cause and examples for the phenomenon described in Statement I, it serves as the correct explanation for Statement I.

Question 22

Consider the following statements regarding the characteristics of services:
1. High-order services, such as those provided by accountants and physicians, are generally more common and widespread than low-order services like grocery shops.
2. The location for recreational services like a golf course is typically chosen within or near the Central Business District (CBD) to maximize market access.
3. Personal service workers, such as housekeepers and gardeners, are often unskilled migrants from rural areas and are generally part of the unorganised sector.
How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is incorrect. Low-order services, such as grocery shops and laundries, are by their nature more common and widespread to meet frequent, universal needs. High-order services are specialized and cater to a smaller client base, making them less common. The statement reverses this relationship. Statement 2 is incorrect. The economic logic for locating a land-intensive facility like a golf course is to seek areas where land costs are lower, which is typically away from the expensive real estate of a Central Business District (CBD). High-accessibility services like restaurants are more suited to CBD locations. Statement 3 is correct. The personal services sector in many economies is characterized by unskilled labor, often comprising migrants from rural areas. These workers, employed in domestic roles, typically operate within the unorganised sector. Therefore, only one statement is correct.

Question 23

With reference to medical tourism and related services, consider the following statements:
1. India has emerged as the leading country for medical tourism, with world-class hospitals in its metropolitan cities catering to a global clientele.
2. The profitability of outsourcing IT-related job-work to countries like India, China, and Botswana is driven by lower wages and significantly lower overhead costs.
3. In 2005, the volume of patients from the U.S.A. seeking treatment in India represented a significant proportion, nearly half, of the total surgeries performed in the U.S. healthcare system.
How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. India is identified as the leading country for medical tourism, utilizing its world-class hospitals in metropolitan cities to serve patients from around the world. Statement 2 is correct. The profitability of outsourcing IT services to overseas countries is attributed to the availability of skilled, English-speaking staff at lower wages and much lower overhead costs, making the practice economically advantageous. Statement 3 is incorrect. This is a scale distortion. The 55,000 patients from the U.S.A. in 2005 are specifically described as a 'small number' when compared to the 'millions of surgeries' performed annually in the U.S. healthcare system. It was a small fraction, not a significant proportion like 'nearly half'. Therefore, only two statements are correct.

Question 24

Consider the following statements regarding factors that determine tourist attractions:
1. A primary factor for a landscape's tourist appeal is its significant alteration by human activity to provide modern amenities.
2. The economic viability of a region, specifically its ability to offer services at a low cost, is a key driver of its popularity among tourists.
3. The climatic requirements for winter holidays are exclusively limited to regions with significant snow cover for skiing.

How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is incorrect. Tourist appeal in landscapes is often associated with environments that are not completely altered by human intervention, such as mountains, lakes, and spectacular sea coasts. Statement 2 is correct. A region's popularity among tourists is significantly influenced by its economic attractiveness; providing for tourist needs at a cheap cost makes a destination more likely to become popular. Statement 3 is incorrect. The climatic requirements for winter holidays are not singular. Tourists may seek either higher temperatures than their homelands or snow cover suitable for skiing. The use of the word 'exclusively' makes the statement false as it ignores the alternative preference for warmer climates. Therefore, only one statement is correct.

Question 25

With reference to the economic and developmental impact of tourism, consider the following statements:
1. Based on the total number of registered jobs, tourism is recognized as the world's single largest tertiary activity.
2. The growth of tourism directly fosters the development of related industries such as infrastructure, retail trading, and craft industries.
3. The total revenue generated by global tourism constitutes forty per cent of the world's total Gross Domestic Product (GDP).

How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. Tourism is classified as the world's single largest tertiary activity when measured by the total number of registered jobs, which is approximately 250 million. Statement 2 is correct. Tourism acts as a significant catalyst for economic development by stimulating growth in ancillary sectors. This includes the development of infrastructure, an increase in retail trading, and the promotion of local craft industries that produce items like souvenirs. Statement 3 is incorrect. This statement contains a major Ratio/Scale Distortion. While tourism generates substantial revenue, the claim that it accounts for 40% of the total world GDP is a gross overstatement. The actual contribution of tourism to global GDP is a small fraction of this figure, making the statement factually incorrect.

Question 26

Consider the following rows matching a type of Tourist Attraction with its corresponding example or characteristic:
Row 1: Climate Attraction - Winter sports regions in mountainous areas.
Row 2: Culture & Economy Attraction - Heritage home-stays in Madikere and Coorg.
Row 3: Landscape Attraction - Exploring castles, palaces, and churches.

In how many of the above rows is the given information correctly matched?

Accepted Answer

Only two rows. Row 1 is correctly matched. The need for specific climatic conditions, such as snow cover for skiing, is a climate-based attraction. Winter sports regions in mountainous areas directly correspond to this. Row 2 is correctly matched. The emergence of home-stays, such as the heritage homes in Madikere and Coorg, is explicitly linked to tourism driven by Culture and Economy, where tourists experience local customs and find cost-effective options. Row 3 is incorrectly matched. This is a Terminology Swap trap. Exploring castles, palaces, and churches falls under the category of 'History and Art' attractions. 'Landscape' attractions are defined by natural features like mountains, lakes, and spectacular sea coasts, not man-made historical structures.

Question 27

With reference to the hierarchical classification of the Service Sector, consider the following statements:
1. 'Means of transportation' is classified as a sub-category of 'Communication'.
2. The Public Distribution System (PDS) is shown as a form of retail trade present in both urban and rural categories.
3. Non-Governmental Organisations (NGOs) are classified under Quinary Activities.
How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. In the standard economic classification of services, 'Means of transportation' is categorized under 'Communication'. This is based on the concept that all forms of transport function as lines of communication. Statement 2 is correct. The Public Distribution System (PDS) is a form of retail trade that operates in both urban and rural markets, hence its classification reflects this dual presence. Statement 3 is incorrect. Non-Governmental Organisations (NGOs) are classified under 'Personal and Professional' services, which is a sub-category of Tertiary Activities. Quinary Activities are a separate, higher-level category involving specialists, decision-makers, and policy formulators.

Question 28

Consider the following rows matching the 'colour of the collar' with the nature of work:
Row 1: Gold Collar - Workers associated with the highest levels of decision making or new technologies (Quinary activities).
Row 2: Red Collar - Workers engaged in primary sector activities such as agriculture or mining.
Row 3: Pink Collar - Highly paid professionals working in office environments.
In how many of the above rows is the given information correctly matched?

Accepted Answer

Only two rows. Row 1 is correctly matched. 'Gold collar' professionals are associated with Quinary activities, which involve high-level decision-making, research, and ideation. Row 2 is correctly matched. 'Red collar' workers are those engaged in primary activities, which involve the extraction of raw materials from the earth. Row 3 is incorrectly matched. 'Pink collar' refers to workers in the service industry, which are often not highly paid. Highly paid professionals in office environments are typically referred to as 'White collar' workers. Therefore, only two of the rows are correctly matched.
