Q4552. Consider the following statements regarding Small Hydropower (SHP) in India:
I. Projects up to 25 MW are classified as Small Hydropower.
II. SHP projects are entirely managed by the Ministry of Power, not the Ministry of New and Renewable Energy.
III. They have a shorter gestation period compared to large hydropower projects.
IV. They are particularly suitable for electrification of remote and hilly areas.
Which of the above statement(s) is/are correct?
I. Projects up to 25 MW are classified as Small Hydropower.
II. SHP projects are entirely managed by the Ministry of Power, not the Ministry of New and Renewable Energy.
III. They have a shorter gestation period compared to large hydropower projects.
IV. They are particularly suitable for electrification of remote and hilly areas.
Which of the above statement(s) is/are correct?
Explanation
Small Hydropower projects, with capacities up to twenty-five megawatts, are managed by the Ministry of New and Renewable Energy. They offer the advantages of shorter gestation periods and lower environmental impacts compared to large dams. These projects are particularly vital for providing electricity to remote and hilly areas where extending the national grid is difficult, making them essential for regional energy security.
Q4553. The implementation of precision agriculture in Rajasthan is directly beneficial for mitigating the effects of:
Explanation
Implementing precision agriculture in Rajasthan is directly beneficial for mitigating the challenges posed by high variability in soil and climate conditions. Since soil fertility and moisture levels can vary significantly even within a single field, uniform farming often leads to wastage or under-performance. Precision techniques allow for site-specific management, ensuring that every part is treated according to requirements.
Q4554. Arrange the following historical events related to peasant movements in Rajasthan in chronological order:
I. Establishment of Rajasthan Seva Sangh
II. Start of the Begun Peasant Movement
III. Dabi Massacre in Bundi
IV. Final withdrawal of the Bijolia Movement
Select the correct order from the options given below:
I. Establishment of Rajasthan Seva Sangh
II. Start of the Begun Peasant Movement
III. Dabi Massacre in Bundi
IV. Final withdrawal of the Bijolia Movement
Select the correct order from the options given below:
Explanation
The Rajasthan Seva Sangh was set up in 1919. The Begun movement began in 1921, the Dabi massacre of Bundi took place in 1923, and the Bijolia movement was finally withdrawn in 1941. The correct order is I, II, III, IV.
Q4555. Match List I with List II and select the correct answer using the codes given below:
| Emergency | Time given for Parliamentary Approval |
|---|---|
| A. National Emergency | i. 2 months |
| B. President’s Rule | ii. 1 month |
| C. Financial Emergency | iii. 2 months |
| D. Revocation of National Emergency | iv. No approval required |
Explanation
Proclamations of emergency require parliamentary approval within specific timeframes. National Emergency needs approval within one month. President’s Rule and Financial Emergency both require approval within two months. However, the revocation of a National Emergency by the President does not require any parliamentary approval, although the Lok Sabha can force a revocation through a resolution passed by a simple majority.
Q4556. All of the following are significant, traversable mountain passes located within the Western Ghats EXCEPT:
Explanation
Thal Ghat, Bhor Ghat, and Pal Ghat are critical mountain passes that allow transportation across the rugged Western Ghats. In contrast, the Haldighati Pass is located in the Aravalli Range of Rajasthan. It is historically significant but does not belong to the Western Ghats. The Western Ghats passes are essential for connecting the coastal plains with the interior regions of the plateau.
Q4557. What is the primary cause of frequent technical and maintenance challenges in hydropower projects situated in the Himalayan region?
Explanation
Hydropower projects in the Himalayan region face frequent challenges due to the area’s fragile geological formations and high levels of silt in the rivers. High siltation causes rapid wear and tear on turbines, while geological instability leads to landslides and construction delays. These factors make the development and maintenance of hydropower in this mountainous terrain significantly more technical and costly.
Q4558. Analyze the following cause and effect statements and select the correct option: Cause: Precision agriculture utilizes micro-irrigation systems coupled with soil moisture sensors. Effect: There is a significant increase in the water use efficiency of crops in arid regions.
Explanation
Precision agriculture integrates micro-irrigation systems with soil moisture sensors to ensure that water is applied only when and where it is needed. This targeted approach directly results in a significant increase in water use efficiency. In the arid regions of Rajasthan, where water is a scarce resource, such technological integration is vital for sustainable crop production and viability.
Q4559. What was a significant sociological effect observed during the Bundi Peasant Movement?
Explanation
Local women took part actively in the Bundi peasant movement. They faced the police and supported the peasants. The other options, such as abolition of caste, mass conversion and migration, did not happen.
Q4560. Which factor acts as a primary cause driving the balance of federalism towards a unitary structure during emergency provisions?
Explanation
During an emergency, the centralization of executive and legislative powers is the primary factor shifting the federal balance toward a unitary structure. This centralization is intended to ensure national security and a coordinated response to crises. It allows the Union to override state autonomy, ensuring that the country operates as a single unit to overcome the challenges posed.Answer key for these questions
