Which among the above is / are correct?
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 nor 2

4. Which of the following is / are correct observations about Rice Cultivation in India?
- Most of the rice produced in India is Winter Rice
- Rice farming in India is characterized by heavy farm mechanization
Select the correct option from the codes given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: A [Only 1]
Notes:
Autumn Rice is Pre-Kharif rice sown during May to August; and harvested in September-October. Autumn rice crop accounts for only 7-8% of total rice grown. Winter Rice is the Kharif rice in India, sown in June-July and harvested in November-December. This accounts for 84% rice cultivation in India. Summer rice is also called Rabi rice sown from November to February and harvesting time is March to June. This accounts for 8-9% of total rice cultivated in India.
Thus, rice is predominantly a Kharif crop in India, grown in both irrigated areas as well as rain-fed areas with high rainfall. It requires hot and humid conditions for growing with 24° C mean temperature and 150-300 cm rainfall. The crop is predominantly labor oriented and is not much suitable for heavy farm mechanization.
5. Which of the following is / are correct statements about the Deccan Trap?
- It is spread in all states of Peninsular India
- It is made of predominantly Igneous Rocks
- It formed as result of sub-aerial volcanic activity
Select the correct option from the codes given below:
[A] Only 1 & 2
[B] Only 2 & 3
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: B [Only 2 & 3]
Notes:
Some people broadly divide the geographical land area of India into three parts viz. Deccan trap, Gondwana and Vindhyan. The Deccan Trap covers almost all of Maharashtra, some parts of Gujarat, Karnataka, Madhya Pradesh and marginally Andhra Pradesh. Deccan Trap is thought to have formed as result of sub-aerial volcanic activity associated with the continental deviation in this part of the Earth during the Mesozoic era. This implies that generally, the rocks of Deccan Trap are igneous.
6. Consider the following statements regarding the Lakshadweep islands:
- The majority of islands in the Lakshadweep archipelago are uninhabited.
- Snake species are almost absent in the Lakshadweep islands.
Which of the above statements is / are correct?
[A] Only 1
[B] Both 1 and 2
[C] Only 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: B [Both 1 and 2]
Notes:
Out of 36 islands in Lakshadweep, only 10 are inhabited, making the uninhabited majority. The presence of snakes is rare in Lakshadweep due to its isolation and unique ecological conditions; only a few sea snakes and some non-venomous snakes are occasionally reported. Therefore, both statements are correct.
7. Consider the following pairs:
- Bunder project – Diamond
- Hirabuddini project – Gold
- Jaduguda project – Uranium
Which of the above is/are correct?
[A] 1 & 3 Only
[B] 3 Only
[C] 2 & 3 Only
[D] 1, 2 & 3
Show Answer
Correct Answer: D [ 1, 2 & 3]
Notes:
The Bunder project was recently in news when the mining giant Rio Tinto decided to shut down its Rs 2,200-crore diamond mining project in Madhya Pradesh (MP). The Bunder diamond project was discovered in 2004 by the Australia-based mining major and in 2010 it inked an agreement with Madhya Pradesh for the development of the project. Hutti and Uti in Karnataka and the Hirabuddini mines in Jharkhand are the only gold producing mines in India. Jaduguda in Jharkhand is known for Uranium mines
8. Consider the following rivers:
- Damodar
- Subarnarekha
- Chambal
- Banas
Which of the above have superimposed drainage?
[A] 1, 2 & 3 Only
[B] 2, 3 & 4 Only
[C] 1, 2 & 4 Only
[D] 1, 2, 3 & 4
Show Answer
Correct Answer: D [ 1, 2, 3 & 4]
Notes:
The Damodar, the Subarnarekha, the Chambal, the Banas rivers are good examples of superimposed drainage. A superimposed river does not adjust with the structure of its place of origin.
9. Consider the following about Krishna-Godavari (KG) Basin:
- It is the largest river basin in India
- It is home to Olive Ridley turtles
- It has good prospects of tight oil and tight gas reserves
Which of the above statements is/are correct?
[A] 1 & 3 Only
[B] 2 & 3 Only
[C] 3 Only
[D] 1, 2 & 3
Show Answer
Correct Answer: B [2 & 3 Only]
Notes:The first statement is incorrect because the largest river basin in India is the Ganga-Brahmaputra-Meghna system, not the Krishna-Godavari (KG) Basin. The KG Basin does however have good prospects for tight oil and tight gas reserves, and it is home to Olive Ridley turtles.
- The Ganga-Brahmaputra-Meghna system is the largest river basin in India
- The Olive Ridley turtles are found in the KG Basin
- The KG Basin has good prospects of tight oil and tight gas reserves
10. Consider the following traditional water management system with states to which they are associated:
- Dongs – Assam
- Jampois – West Bengal
- Bandhas – Odisha
Which of the above is/are correct?
[A] 1 & 2 Only
[B] 3 Only
[C] 2 & 3 Only
[D] 1, 2 & 3
Show Answer
Correct Answer: D [ 1, 2 & 3]
Notes:
Dongs are ponds constructed by the Bodo tribes of Assam to harvest water for irrigation. Jampois are small irrigation channels linking rice fields to streams in the Jalpaiguri district of West Bengal. The katas, mundas and bandhas were the main irrigation sources in the ancient tribal kingdom of the Gonds (now in Odisha and Madhya Pradesh).
