Q9452. Match the missiles developed by DRDO in List I with their correct operational types in List II.
| Missile Name | Operational Type |
|---|---|
| A. Prithvi | i. Anti-tank guided missile |
| B. Trishul | ii. Intermediate-range ballistic missile |
| C. Nag | iii. Short-range surface-to-surface ballistic missile |
| D. Agni | iv. Short-range surface-to-air missile |
Explanation
The Integrated Guided Missile Development Programme produced several distinct systems for defense. Prithvi is a short-range surface-to-surface ballistic missile, while Trishul serves as a short-range surface-to-air defense system. Nag was designed specifically as an anti-tank guided missile with fire-and-forget capabilities. Agni represents a series of intermediate to long-range ballistic missiles, forming a critical component of India’s strategic deterrent capabilities.
Q9453. In India’s three-stage nuclear power programme, the second stage involves the use of Fast Breeder Reactors (FBR). Which of the following fuels is bred in the blanket of the FBR to be used in the third stage of the programme?
Explanation
The second stage of the Indian nuclear power programme utilizes Fast Breeder Reactors. In these reactors, a blanket of thorium-232 is placed around the core. Through the process of neutron absorption, the thorium is converted into fissile uranium-233. This bred fuel is intended for use in the third stage of the programme, which focuses on utilizing India’s abundant thorium resources.
Q9454. Which of the following statements regarding the establishment of the Indian Institutes of Technology (IITs) post-independence is incorrect?

The later Institutes of Technology Act of 1961 formally recognized these institutions nationwide.
Q9455. Consider the following key milestones in India’s post-independence scientific history:
I. Adoption of the Scientific Policy Resolution
II. Establishment of the Indian Space Research Organisation (ISRO)
III. Launch of the Aryabhata satellite
IV. First nuclear test at Pokhran
V. Establishment of the Department of Biotechnology (DBT)
Which of the above events occurred before 1980?
I. Adoption of the Scientific Policy Resolution
II. Establishment of the Indian Space Research Organisation (ISRO)
III. Launch of the Aryabhata satellite
IV. First nuclear test at Pokhran
V. Establishment of the Department of Biotechnology (DBT)
Which of the above events occurred before 1980?
Explanation
Several major scientific milestones occurred in the early decades after independence. The Scientific Policy Resolution was adopted in 1958, and ISRO was established in 1969. The first nuclear test at Pokhran took place in 1974, followed by the launch of the Aryabhata satellite in 1975. In contrast, the Department of Biotechnology was not established until 1986, after the 1980 threshold.
Q9456. The series of five nuclear bomb test explosions conducted by India at the Pokhran Test Range in May 1998 was carried out under the leadership of which Prime Minister?
Explanation
The series of five nuclear tests in May 1998, known as Operation Shakti, occurred under the political leadership of Prime Minister Atal Bihari Vajpayee. These tests confirmed India’s capability to deploy thermonuclear weapons and established the nation as a full-fledged nuclear-armed state. The event had significant geopolitical implications, leading to international sanctions while simultaneously strengthening the country’s national security posture.

Statement II: The Indian IT industry initially grew rapidly by catering exclusively to the domestic market before expanding to global outsourcing.
Identify the correct statement from the options below.
Explanation
The Software Technology Parks of India scheme was launched in 1991 to boost software exports through tax incentives and infrastructure support. Unlike many industries, the Indian IT sector did not rely on the domestic market first. Instead, it grew rapidly by focusing on global outsourcing and international service delivery, leveraging skilled labor to meet the demands of foreign clients successfully.
Q9458. Which district of Rajasthan recorded the highest total population in the 2011 Census?
Explanation
Jaipur serves as the most populous district in Rajasthan according to the 2011 Census results.

Other districts like Jodhpur and Alwar also have significant populations, but they remain lower than the total count recorded in Jaipur.
Q9459. The Council of Scientific and Industrial Research (CSIR) operates a wide network of national laboratories. Which of the following is NOT a laboratory operating under the CSIR network?
Explanation
The Council of Scientific and Industrial Research oversees numerous national laboratories like the National Chemical Laboratory and National Physical Laboratory. These institutions focus on civil scientific research and industrial development. In contrast, the Defence Research and Development Laboratory is a major facility under the Defence Research and Development Organisation. Its primary mandate involves the design and development of missile systems.
