Question 1

Consider the following statements regarding the characteristics and classification of minerals: 1. Coal and petroleum are classified as organic non-metallic minerals. 2. All metallic minerals, such as copper and bauxite, are classified as ferrous minerals. 3. There is a direct relationship between the quality and quantity of minerals, meaning good quality minerals are generally more abundant. How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is correct. The text classifies non-metallic minerals into organic and inorganic types. It explicitly places coal and petroleum, derived from buried animal and plant life, in the organic category as fossil fuels. Statement 2 is incorrect. The text distinguishes metallic minerals into ferrous (with iron content) and non-ferrous (without iron content). It explicitly cites copper and bauxite as examples of non-ferrous minerals. Therefore, not all metallic minerals are ferrous. Statement 3 is incorrect. The text states there is an 'inverse relationship in quality and quantity of minerals,' meaning good quality minerals are less common than low quality ones. The statement claims a 'direct relationship,' which is the opposite. Therefore, only one statement is correct.

Question 2

Consider the following statements:
Statement I: The vast alluvial plain tract of north India is devoid of minerals of economic use.
Statement II: India's valuable minerals are products of the pre-palaeozoic age and are mainly associated with metamorphic and igneous rocks of peninsular India.

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 northern plains of India, being vast alluvial tracts formed by geologically recent river deposits, are largely devoid of economically significant mineral resources. Statement II is also correct. India's most valuable mineral deposits are found in the peninsular region, associated with ancient metamorphic and igneous rocks dating back to the pre-Palaeozoic era. Statement II provides the direct geological reason for the spatial distribution pattern mentioned in Statement I. The formation of valuable minerals is a process that occurs over geological time in specific rock types (igneous and metamorphic). The peninsular plateau consists of these ancient, mineral-rich rocks. In contrast, the northern plains are composed of geologically recent, unconsolidated sediments (alluvium), which do not host these types of mineral deposits. Therefore, the geological character of the peninsula described in Statement II explains the lack of minerals in the alluvial plains mentioned in Statement I.

Question 3

Consider the following pairs:
1. Gold : Ferrous Metallic
2. Coal : Inorganic Non-metallic
3. Bauxite : Non-ferrous Metallic
4. Graphite : Inorganic Non-metallic

How many of the above pairs are correctly matched?

Accepted Answer

Only two pairs. Statement 1 is incorrectly matched. Gold is a metallic mineral, but it is non-ferrous as it does not have iron content. Ferrous minerals are those which have iron content. Statement 2 is incorrectly matched. Coal is a non-metallic mineral of organic origin, derived from buried plant life. It is not inorganic. Statement 3 is correctly matched. Bauxite is a metallic mineral that does not contain iron, classifying it as non-ferrous. Statement 4 is correctly matched. Graphite is a non-metallic mineral of inorganic origin. Therefore, only two pairs (3 and 4) are correctly matched.

Question 4

Consider the following statements regarding the major mineral belts of India:
1. The South-Western Plateau Region, while rich in ferrous metals and bauxite, has less diversified mineral deposits compared to the north-eastern belt and is largely deficient in coal.
2. The North-Western Region is associated with the Dharwar system of rocks and contains both major non-ferrous metals like copper and zinc, and significant petroleum deposits.
3. The North-Eastern Plateau Region, covering Chhotanagpur and the Odisha Plateau, is noted for a variety of minerals including coal and iron ore, but significant petroleum reserves are found outside this belt in areas like the Assam valley.

Accepted Answer

All three. Statement 1 is correct. The South-Western Plateau Region (Karnataka, Goa, Tamil Nadu uplands, Kerala) is characterized by a lower diversity of mineral deposits compared to the North-Eastern belt. It is also largely deficient in coal, with the exception of Neyveli lignite. Statement 2 is correct. The North-Western Region's mineral deposits, found along the Aravali in Rajasthan and parts of Gujarat, are geologically associated with the Dharwar system of rocks. This region is a source of major non-ferrous metals like copper and zinc, and Gujarat is known for its petroleum deposits. Statement 3 is correct. The North-Eastern Plateau Region is rich in minerals like iron ore and coal. However, significant petroleum reserves are located in separate geological formations, such as the sedimentary basins of the Assam valley, which is distinct from this plateau belt. Since all three statements are correct, the correct option is (c).

Question 5

Consider the following rows regarding the classification of minerals:
Row 1: Ferrous Mineral : Copper
Row 2: Fuel Mineral : Petroleum
Row 3: Non-Ferrous Mineral : Manganese
In how many of the above rows is the mineral correctly classified?

Accepted Answer

Only one row. Row 1 is incorrectly matched. Copper is a non-ferrous mineral, meaning it does not contain significant amounts of iron. Ferrous minerals, by definition, contain iron. Row 2 is correctly matched. Petroleum is a fossil fuel and is classified as a fuel mineral. Row 3 is incorrectly matched. Manganese is a ferrous mineral, often found in association with iron ore and used in steelmaking. Therefore, only one row is correctly matched.

Question 6

Based on the standard classification of minerals, consider the following rows:
Row 1: Ferrous Mineral : Bauxite
Row 2: Fuel Mineral : Limestone
Row 3: Non-Ferrous Mineral : Copper
In how many of the above rows is the mineral correctly matched with its classification?

Accepted Answer

Only one row. Row 1 is incorrectly matched. Bauxite is a non-ferrous metallic mineral, not a ferrous one. Ferrous minerals are defined by the presence of iron. Row 2 is incorrectly matched. Limestone is classified as an 'Other non-metallic' mineral used in industries like cement; it is not a fuel mineral like coal or petroleum. Row 3 is correctly matched. Copper is a classic example of a non-ferrous metallic mineral. Therefore, only one row is correctly matched.

Question 7

Consider the following statements regarding the spatial distribution of ferrous minerals in India based on geographical data:
1. The Bailadila iron ore mines in Chhattisgarh represent the southernmost extent of the major eastern iron ore belt.
2. The Balaghat manganese mine in Madhya Pradesh is the only ferrous mineral mine shown located north of the Tropic of Cancer.
3. The Kudremukh iron ore mine in Karnataka is situated to the east of Tumakuru and Chikkamagaluru.
How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. The provided data explicitly identifies the Bailadila mines as the southernmost in the eastern belt shown on the map. Statement 2 is correct. The data notes that no ferrous mineral mines are shown north of the Tropic of Cancer, with the sole exception of the Balaghat manganese mine, which is located just north of it. Statement 3 is incorrect. This is a spatial swap trap. The data specifies that the Kudremukh mine is located to the west of Tumakuru and Chikkamagaluru, not to the east. Therefore, only two statements are correct.

Question 8

Consider the following rows matching iron ore exporting ports with the mineral belts they primarily serve:
Row 1: Paradwip Port - Eastern iron ore belt (Odisha-Jharkhand region)
Row 2: Marmagao Port - Western iron ore belt (Goa-Karnataka region)
Row 3: Mangaluru Port - Eastern iron ore belt (Odisha-Jharkhand region)
In how many of the above rows is the information correctly matched?

Accepted Answer

Only two rows. Row 1 is correctly matched. The spatial data confirms that Paradwip port, located on the east coast, serves the eastern iron ore belt. Row 2 is correctly matched. The data indicates that Marmagao port on the west coast serves the western/southern belts, including the Goa-Karnataka region. Row 3 is incorrectly matched. This is a spatial swap. Mangaluru port is on the west coast and serves the western/southern belts (specifically the Kudremukh mines), not the eastern belt. Therefore, only two rows are correctly matched.

Question 9

Consider the following states and their associated manganese mining districts:
1. Odisha: Kendujhar, Sundergarh, Koraput
2. Madhya Pradesh: Balaghat, Chhindwara, Jhabua
3. Maharashtra: Nagpur, Bhandara, Ratnagiri
How many of the above pairings are correctly matched?

Accepted Answer

All three. Statement 1 is correct. Kendujhar, Sundergarh, and Koraput are all major manganese mining areas located in Odisha. Statement 2 is correct. The manganese belt of Madhya Pradesh extends through the districts of Balaghat, Chhindwara, and Jhabua. Statement 3 is correct. In Maharashtra, manganese is mined in the districts of Nagpur, Bhandara, and Ratnagiri. Since all three statements correctly pair the state with its manganese mining districts, the correct count is three.

Question 10

Based on the spatial distribution of ferrous minerals in India, consider the following statements:
1. The Kudremukh iron ore mine is situated west of Tumakuru and primarily utilizes the Mangaluru port for exports.
2. The Tropic of Cancer passes north of the iron ore mines in Durg and Sundergarh, but south of the Gua mine.
3. The Bailadila mines in Chhattisgarh represent the northernmost mines within the eastern iron ore belt.
How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. The Kudremukh mine is located in Karnataka, west of other mining areas like Tumakuru, and its proximity to the west coast makes Mangaluru its logical exporting port. Statement 2 is correct. This statement accurately describes the latitudinal position of the Tropic of Cancer relative to the major iron ore mines in the eastern belt. Statement 3 is incorrect. This is a spatial swap. The Bailadila mines are the southernmost mines in the eastern belt shown on the map, not the northernmost. Therefore, only two statements are correct.

Question 11

Consider the following statements regarding iron ore mining locations in India:
1. The important mines of Gurumahisani and Badampahar are located in the Kendujhar district of Odisha.
2. In Karnataka, significant iron ore deposits are found in the Baba Budan hills and Kudremukh in the Chikkamagaluru district.
3. The Dalli and Rajhara mines, located in the Dantewara district, are important iron ore mines in Chhattisgarh.
How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is incorrect. The Gurumahisani and Badampahar mines are located in the Mayurbhanj district of Odisha. The Kiruburu mine is associated with the Kendujhar district. Statement 2 is correct. In Karnataka, iron ore deposits occur in the Baba Budan hills and Kudremukh, which are in the Chikkamagaluru district. Statement 3 is incorrect. The Dalli and Rajhara mines are located in the Durg district of Chhattisgarh, not the Dantewara district. Therefore, only one of the given statements is correct.

Question 12

Consider the following statements regarding India's position in the iron and steel industry:
1. India holds the sixth-largest iron ore deposits globally.
2. Secondary producers, such as re-rollers, contribute to approximately one-third of the total crude steel production in India.
3. India is the world's largest producer of coal-based sponge iron, contributing about one-quarter of the global output.
How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. India ranks sixth in the world in terms of iron ore deposits. Statement 2 is correct. Secondary producers account for 33% of steel production, which is approximately one-third. Statement 3 is incorrect. This is a ratio distortion trap. While India is the largest producer of coal-based sponge iron in the world, it accounts for 15% of global output. 15% is not equivalent to 'about one-quarter' (25%). Therefore, only two statements are correct.

Question 13

Consider the following rows matching iron ore mining regions with their respective states:
Row 1: Sundergarh : Jharkhand
Row 2: Noamundi : Odisha
Row 3: Ballari : Karnataka
Row 4: Salem : Tamil Nadu
In how many of the above rows is the iron ore mining region correctly matched with its state?

Accepted Answer

Only two rows. Let's evaluate each row: Row 1 is incorrectly matched. Sundergarh, known for the Bonai iron ore range, is in Odisha, not Jharkhand. Row 2 is incorrectly matched. Noamundi is one of the most important mines in the Poorbi and Pashchimi Singhbhum districts of Jharkhand, not Odisha. Row 3 is correctly matched. The Sandur-Hospet area of Ballari district is a major iron ore region in Karnataka. Row 4 is correctly matched. The text identifies Salem district as a location for iron ore in Tamil Nadu. Therefore, only two rows (3 and 4) are correctly matched.

Question 14

With reference to India's position in the global and domestic iron and steel sector, consider the following statements:
1. India possesses the largest reserve of iron ore in Asia.
2. Secondary producers, such as re-rollers, account for approximately two-thirds of the total crude steel production in India.
3. India is the largest producer of coal-based sponge iron in the world, accounting for more than one-quarter of global output.
How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is correct. India has the largest reserve of iron ore in Asia. Statement 2 is incorrect. Secondary producers account for 33% of total crude steel production, which is equivalent to one-third, not the two-thirds (approximately 67%) claimed in the statement. Statement 3 is incorrect. While India is the world's largest producer of coal-based sponge iron, its share of global output is 15%, which is significantly less than one-quarter (25%). Therefore, only one statement is correct.

Question 15

Consider the following pairs of iron ore mines and their corresponding locations:
1. Gurumahisani : Sundergarh district
2. Noamundi : Pashchimi Singhbhum district
3. Dalli-Rajhara : Dantewara district
4. Kudremukh : Chikkamagaluru district
How many of the above pairs are correctly matched?

Accepted Answer

Only two pairs. Pair 1 is incorrectly matched. The Gurumahisani mines are located in the Mayurbhanj district of Odisha, not Sundergarh. Pair 2 is correctly matched. The Noamundi mines are located in the Pashchimi Singhbhum district of Jharkhand. Pair 3 is incorrectly matched. The Dalli and Rajhara mines are in the Durg district of Chhattisgarh, not Dantewara. Pair 4 is correctly matched. The Kudremukh iron ore deposits are located in the Chikkamagaluru district of Karnataka. Therefore, only two pairs (2 and 4) are correctly matched.

Question 16

Consider the following statements regarding mineral production sites in India, based on standard geographical data and mineral maps:
1. The Balaghat district in Madhya Pradesh is a significant site for both Copper and Manganese deposits.
2. The Singhbhum district in Jharkhand is noted for deposits of both Iron Ore and Copper.
3. The Amarkantak plateau, a major bauxite region, is located entirely within the state of Madhya Pradesh.

How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. The provided 'High-Yield Hooks' from map analysis explicitly state that Balaghat (MP) is a site for both Manganese and Copper. Statement 2 is correct. The 'High-Yield Hooks' also confirm that Singhbhum (Jharkhand) is marked for both Iron Ore and Copper. Statement 3 is incorrect. The text states, 'Chhattisgarh has bauxite deposits in Amarkantak plateau,' and the map notes specify that the deposits are at the 'junction of Madhya Pradesh and Chhattisgarh.' Therefore, the plateau is not located entirely within Madhya Pradesh. Since only statements 1 and 2 are correct, the correct option is 'Only two'.

Question 17

Consider the following rows regarding non-ferrous and non-metallic minerals in India:
Row 1: Bauxite : Patlands of Lohardaga : Jharkhand
Row 2: Copper : Jhunjhunu and Alwar districts : Madhya Pradesh
Row 3: Mica : Nellore district : Andhra Pradesh

In how many of the above rows is the mineral, its deposit location, and the corresponding state correctly matched?

Accepted Answer

Only two rows. Row 1 is correctly matched. The patlands of Lohardaga in Jharkhand are known for their rich bauxite deposits. Row 2 is incorrectly matched. While Jhunjhunu and Alwar districts are major centers for copper deposits, they are located in the state of Rajasthan, not Madhya Pradesh. Row 3 is correctly matched. Nellore district in Andhra Pradesh is a key area for the production of best-quality mica. Since two of the three rows are correctly matched, the correct option is (b).

Question 18

Consider the following statements regarding mineral production in India:
1. Odisha is the largest producer of Bauxite, with Kalahandi and Sambalpur being leading producing areas.
2. Copper deposits in India mainly occur in the Singhbhum district of Jharkhand, the Balaghat district of Madhya Pradesh, and the Jhunjhunu and Alwar districts of Rajasthan.
3. In the context of Mica production, the belt in Rajasthan is significantly longer than the belt in Jharkhand.

How many of the above statements are correct?

Accepted Answer

All three. Statement 1 is correct. Odisha is identified as the largest producer of Bauxite, and Kalahandi and Sambalpur are specifically named as the leading producers. Statement 2 is correct. The three primary locations for copper deposits are explicitly listed as Singhbhum district (Jharkhand), Balaghat district (Madhya Pradesh), and Jhunjhunu and Alwar districts (Rajasthan). Statement 3 is correct. The mica belt in Jharkhand extends for about 150 km, whereas the mica belt in Rajasthan extends for about 320 km from Jaipur to Bhilwara, making it significantly longer. Therefore, all three statements are correct.

Question 19

Consider the following statements regarding the distribution of Mica in India:
1. The mica belt in Jharkhand, extending over 150 km in length, is shorter than the mica belt in Rajasthan.
2. In Southern India, commercially significant mica deposits are found in the states of Karnataka, Tamil Nadu, and Kerala.
3. For strategic conservation, India's policy should prioritize the export of scarce metals like copper and zinc to generate revenue.

How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. The text specifies the Jharkhand mica belt is 'about 150 km, in length' and the Rajasthan belt 'extends for about 320 kms'. Thus, the Jharkhand belt is shorter. Statement 2 is correct. The text lists mica deposits in 'Mysuru and Hasan districts of Karanataka, Coimbatore, Tiruchirapalli, Madurai and Kanniyakumari in Tamil Nadu, Alleppey in Kerala', confirming deposits in all three southern states. Statement 3 is incorrect. This is a causality reversal. The text on conservation explicitly states, 'Export of strategic and scarce minerals must be reduced, so that the existing reserve may be used for a longer period.' The statement suggests the opposite. Therefore, only statements 1 and 2 are correct.

Question 20

Consider the following pairs of Coal Fields/Mines and their corresponding states:
1. Singareni : Andhra Pradesh
2. Kalakot : Jammu and Kashmir
3. Makum : Assam
4. Talcher : Jharkhand

How many of the above pairs are correctly matched?

Accepted Answer

Only two. Statement-by-statement analysis:
- Pair 1 is incorrect. The text states that the Singareni coal mining centre is in Telangana, not Andhra Pradesh. This is a common trap related to state reorganization.
- Pair 2 is correct. The text explicitly mentions that Tertiary coal is extracted from Kalakot in Jammu and Kashmir.
- Pair 3 is correct. The text identifies Makum as a Tertiary coal location in upper Assam.
- Pair 4 is incorrect. The text places the Talcher coal field in Odisha, not Jharkhand. While Jharkhand is a major coal state, Talcher specifically is not located there.
Therefore, only two pairs (Kalakot and Makum) are correctly matched.

Question 21

Consider the following statements regarding coal resources in India:
Statement I: The Damodar Valley is considered the primary repository of coal resources in India.
Statement II: This region contains the Jharia coal field, which is the single largest in the country, along with other major fields like Raniganj and Bokaro.
Statement III: The geological foundation of this valley is dominated by Tertiary rock sequences, which are exceptionally rich in bituminous coal.

Which of the statements given above are correct?

Accepted Answer

I and II only. Statement-by-statement analysis:
- Statement I is correct. The text identifies the most important Gondwana coal fields of India as being located in the Damodar Valley, making it the primary hub.
- Statement II is correct. The text explicitly states that the important coal fields in the Damodar Valley region are Raniganj, Jharia, and Bokaro, and that 'Jharia is the largest coal field'.
- Statement III is incorrect. This statement contains a critical error. The text clearly attributes the coal in this region to the 'Gondwana' geological age, not 'Tertiary'. It states, 'Coal occurs in rock sequences mainly of two geological ages, namely Gondwana and tertiary deposits,' and then associates the Damodar Valley fields with Gondwana. Tertiary coals are found elsewhere, such as in Assam and Meghalaya.
Since statements I and II are correct and statement III is incorrect, the correct option is (a).

Question 22

The Hajira-Vijaipur-Jagdishpur (HVJ) pipeline, a major natural gas transport corridor, passes through how many of the following states?
1. Gujarat
2. Rajasthan
3. Chhattisgarh
4. Uttar Pradesh

Accepted Answer

Only three. Analysis of the states listed:
1. Gujarat: Correct. The pipeline originates at Hajira on the coast of Gujarat.
2. Rajasthan: Correct. The spatial intelligence data notes that the pipeline has a branch to Anta in Rajasthan.
3. Chhattisgarh: Incorrect. The pipeline's main route is from Gujarat to Madhya Pradesh and then to Uttar Pradesh. It does not pass through Chhattisgarh. This is a plausible distractor as Chhattisgarh is a major energy-producing state located in central India.
4. Uttar Pradesh: Correct. The pipeline's main northern branch terminates at Jagdishpur in Uttar Pradesh, with several other offtake points within the state.
Thus, the pipeline passes through three of the four states listed: Gujarat, Rajasthan, and Uttar Pradesh.

Question 23

Consider the following statements regarding the geographical distribution of oil refineries in India: 1. Arranged from north to south, the correct sequence of major refineries on the West Coast of India is Jamnagar, Koyali, Mumbai, and Mangaluru. 2. The state of Assam has a higher number of inland oil refineries than any other single state. 3. The Tropic of Cancer passes to the north of the Mathura refinery and to the south of the Bina refinery.

Accepted Answer

Only two. Statement 1 is correct. The provided spatial intelligence lists the West Coast refineries from North to South as: 'Jamnagar/Vadinar, Koyali, Mumbai, Mangaluru, Cochin'. The sequence in the statement is a correct subset of this order. Statement 2 is correct. The provided data lists four refineries in Assam (Bongaigaon, Guwahati, Numaligarh, Digboi), which are all inland. Other states with inland refineries like Haryana, Uttar Pradesh, Madhya Pradesh, and Bihar have only one each, making Assam the state with the highest number. Statement 3 is incorrect. This is a 'Spatial Swap' trap. The provided spatial intelligence states that the Tropic of Cancer passes 'south of the Mathura refinery' and 'north of the Bina refinery'. The statement reverses these relative positions. Therefore, only two statements are correct.

Question 24

Consider the following rows matching petroleum-related sites/terms with their associated state or characteristic: Row 1: Ankaleshwar : Assam. Row 2: Barauni : Market-based refinery. Row 3: Mumbai High : Production commenced in 1973. In how many of the above rows is the given information correctly matched?

Accepted Answer

Only one row. Row 1 is incorrectly matched. This is a 'Spatial Swap' trap. The text clearly states that Ankaleshwar is a major oilfield in Gujarat, not Assam. Row 2 is correctly matched. The text explicitly categorizes refineries and gives 'Barauni is an example of market-based refinery.' Row 3 is incorrectly matched. This is a 'Terminology & Origin Swap' trap. The text states that Mumbai High 'was discovered in 1973 and production commenced in 1976.' The statement incorrectly associates the year of discovery with the commencement of production. Therefore, only one row is correctly matched.

Question 25

Consider the following statements regarding petroleum and natural gas in India: 1. Ankaleshwar and Mehsana are important oil producing areas in Assam. 2. Crude petroleum in India is predominantly found in sedimentary rocks of the tertiary period. 3. The Mumbai High offshore oilfield was discovered and began production before the establishment of the Oil and Natural Gas Commission in 1956. How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is incorrect. Ankaleshwar and Mehsana are major oilfields located in Gujarat, not Assam. The important oil producing areas in Assam mentioned are Digboi, Naharkatiya, and Moran. Statement 2 is correct. The occurrence of crude petroleum is specified to be in the sedimentary rocks of the tertiary period. Statement 3 is incorrect. The Oil and Natural Gas Commission was set up in 1956. Mumbai High was discovered much later in 1973, with production commencing in 1976. Therefore, only one statement is correct.

Question 26

With reference to India's oil refineries and production, consider the following statements: 1. When arranged from North to South, the sequence of refineries along India's West Coast is Jamnagar, Mumbai, and then Cochin. 2. Barauni is an example of a field-based refinery, whereas Digboi is an example of a market-based refinery. 3. The Tropic of Cancer passes to the north of the Mathura refinery and to the south of the Koyali refinery. How many of the above statements are correct?

Accepted Answer

Only one. Statement 1 is correct. The North to South sequence of refineries on the West Coast is given as Jamnagar/Vadinar, Koyali, Mumbai, Mangaluru, Cochin. The subsequence Jamnagar, Mumbai, Cochin maintains this correct relative ordering. Statement 2 is incorrect. This is a terminology swap. Digboi is cited as an example of a field-based refinery, and Barauni is an example of a market-based refinery. The statement reverses this classification. Statement 3 is incorrect. This is a spatial swap. The information specifies that the Tropic of Cancer passes south of the Mathura refinery and north of the Koyali refinery. The statement incorrectly reverses both of these relative positions. Therefore, only one statement is correct.

Question 27

Consider the following pairs of Nuclear Power Projects and their respective states. Row 1: Kalpakkam : Karnataka; Row 2: Narora : Uttar Pradesh; Row 3: Kaiga : Gujarat. In how many of the above rows is the nuclear power project correctly matched with its state?

Accepted Answer

Only one. Statement-wise analysis: Row 1 is incorrectly matched. The Kalpakkam nuclear power project is located in Tamil Nadu, not Karnataka. Row 2 is correctly matched. The Narora nuclear power project is located in Uttar Pradesh. Row 3 is incorrectly matched. The Kaiga nuclear power project is located in Karnataka, not Gujarat. The Kakarapara project is in Gujarat. Therefore, only one of the three rows is correctly matched.

Question 28

With reference to energy sources, consider the following statements: 1. Thorium in India is primarily sourced from monazite deposits found in the beach sands of Kerala and the Mahanadi river delta. 2. Solar energy is considered 10 per cent more effective than nuclear plants and 7 per cent more effective than coal or oil-based plants. 3. The first successful attempt to tap underground heat in Boise, Idaho (USA) was for generating electricity for the city. How many of the above statements are correct?

Accepted Answer

Only two. Statement 1 is correct. Thorium is mainly obtained from monazite, which is found in the beach sands along the coasts of Kerala and Tamil Nadu. The world's richest monazite deposits are located in the Palakkad and Kollam districts of Kerala and the Mahanadi river delta in Odisha. Statement 2 is correct. Solar energy is quantitatively rated as 7 per cent more effective than coal or oil-based plants and 10 per cent more effective than nuclear plants. Statement 3 is incorrect. The first successful geothermal project in Boise, Idaho, was established to create a hot water pipe network for heating surrounding buildings, not for generating electricity. Therefore, only two statements are correct.
