Q1872. The agrarian economy of ancient Rajasthan was heavily reliant on irrigation. Which of the following best describes the early archaeological evidence of water management in the region?
Explanation
Agriculture in ancient Rajasthan required careful water management due to the semi-arid climate. Archaeological evidence at sites like Kalibangan shows the use of wells and tanks for water storage and irrigation. Furthermore, the presence of protective walls suggests they also managed floodwaters. These techniques allowed ancient inhabitants to sustain productive farming and urban life even with limited seasonal rainfall.
Q1873. The directive to organize agriculture and animal husbandry on modern and scientific lines is enshrined in which Article of the Constitution of India?
Explanation
Article forty-eight directs the state to organize agriculture and animal husbandry using modern and scientific methods. This directive aims to improve the productivity and sustainability of the primary sector. It also includes the specific responsibility of preserving and improving livestock breeds and prohibiting the slaughter of essential animals like cows and calves, reflecting both economic and cultural priorities within the agricultural framework.
Q1874. Identify the correct statement regarding the ‘National Monetisation Pipeline’ (NMP).
Explanation
This initiative focuses on generating revenue from existing public infrastructure assets without selling them permanently. The government leases these assets, such as roads, railways, or power lines, to private operators for a specific period in exchange for upfront or periodic payments. This approach allows the state to raise funds for new infrastructure projects while retaining ultimate ownership of the national assets.
Q1875. What specific technology manages the inherently unstable design of the LCA Tejas to keep it flyable?
Explanation
Because the aircraft’s design is inherently unstable to improve its agility, it requires a constant stream of computer-managed adjustments to stay level. This technology replaces traditional mechanical cables with an electronic interface. It monitors pilot inputs and flight conditions thousands of times per second to provide a smooth and controlled experience. This system is essential for the safe operation of modern, highly maneuverable fighter jets that would otherwise be impossible for a human to control.
Q1876. In the context of economic transactions in ancient Rajasthan, which of the following is the odd one out?
Explanation
Karshapana, Pana, and Satamana are all terms for ancient Indian coins or units of currency used for various economic transactions. They were essential for trade and the payment of taxes. A Vihara, however, refers to a Buddhist monastery or a place for monks to live. It is a religious and architectural term rather than an economic one, making it unique.
Q1877. Read the following lists and select the correct answer using the codes given below:
| Clause of Article 39 | Specific Directive |
|---|---|
| A. Article 39(a) | i. Prevention of concentration of wealth |
| B. Article 39(b) | ii. Equal pay for equal work |
| C. Article 39(c) | iii. Adequate means of livelihood |
| D. Article 39(d) | iv. Equitable distribution of material resources |
Explanation
Article thirty-nine (a) concerns adequate means of livelihood, and (b) focuses on the equitable distribution of material resources. Clause (c) aims to prevent the concentration of wealth, while clause (d) mandates equal pay for equal work. These socialistic directives are fundamental to the Constitution’s goal of achieving economic justice and ensuring that the nation’s wealth serves the common good of all.
Q1878. Match the following terms related to disinvestment in List I with their meanings in
List II.
List I: (Term)
A. Initial Public Offering (IPO)
B. Offer for Sale (OFS)
C. Strategic Disinvestment
D. Asset Monetization
List II: (Meaning)
i. Leasing core infrastructure assets to private operators
ii. Unlisted PSU offering shares to the public for the first time
iii. Transfer of ownership and management control
iv. Listed PSU promoters selling shares on the exchange platform
List II.
List I: (Term)
A. Initial Public Offering (IPO)
B. Offer for Sale (OFS)
C. Strategic Disinvestment
D. Asset Monetization
List II: (Meaning)
i. Leasing core infrastructure assets to private operators
ii. Unlisted PSU offering shares to the public for the first time
iii. Transfer of ownership and management control
iv. Listed PSU promoters selling shares on the exchange platform
Explanation
An initial public offering occurs when a company sells shares to the public for the first time. An offer for sale is used by promoters of listed companies to sell their holdings. Strategic disinvestment involves a transfer of control to a private buyer. Asset monetization focuses on leasing out infrastructure to private entities to generate revenue while maintaining public ownership.
Q1879. Consider the following statements:
Statement I: A large portion of the LCA Tejas airframe is built using carbon-fibre composite materials.
Statement II: The use of composite materials increases the aircraft’s weight but reduces its radar signature.
Which of the above statement(s) is/are correct?
Statement I: A large portion of the LCA Tejas airframe is built using carbon-fibre composite materials.
Statement II: The use of composite materials increases the aircraft’s weight but reduces its radar signature.
Which of the above statement(s) is/are correct?
Explanation
A significant portion of the aircraft’s structure is made from advanced carbon-fiber materials. These composites are used because they are much lighter than traditional aluminum while maintaining high strength. This weight reduction allows for better performance and fuel efficiency. Furthermore, these materials also help in reducing the aircraft’s visibility on radar. Suggestions that the use of composites increases the weight of the aircraft are incorrect, as their primary benefit is lightness.
Q1880. Consider the following statements regarding the trade routes and economy of ancient Rajasthan:
I. The region acted as a land-bridge between the prosperous Gangetic valley and the ports of Gujarat.
II. Madhyamika (Nagari) was a prominent commercial hub on the trade route.
III. Trade was entirely controlled by foreign merchants, with no local participation.
IV. Agricultural surplus supported the growth of artisanal crafts and trade.
V. Camels and bullock carts were common modes of transport for goods.
Which of the above statement(s) is/are incorrect?

III. Trade was entirely controlled by foreign merchants, with no local participation.
IV. Agricultural surplus supported the growth of artisanal crafts and trade.
V. Camels and bullock carts were common modes of transport for goods.
Which of the above statement(s) is/are incorrect?
Explanation
Rajasthan acted as a bridge between the Gangetic valley and Gujarat, with centers like Madhyamika thriving on trade. Camels and carts were standard for transport, and agricultural surplus fueled the artisanal economy. However, it is false that trade was entirely controlled by foreign merchants. Local merchants, organized into guilds, played a primary and influential role in both regional and long-distance commerce.Answer key for these questions
