Q9522. Identify the correct pair of districts that have a population density exceeding 500 persons per square kilometer in Rajasthan.
Explanation
In the 2011 Census, only two districts in Rajasthan were found to have a population density exceeding five hundred persons per square kilometer. Jaipur recorded the highest density in the state, followed by Bharatpur. These high figures are due to the fertile nature of the land, better water availability, and significant urban and industrial development in the eastern plains compared to the rest.
Q9523. Identify the correct pair regarding the premier scientific research institutes and their locations in India.
Explanation
India has numerous specialized research institutes under the CSIR. The Centre for Cellular and Molecular Biology is based in Hyderabad, and the Central Drug Research Institute is located in Lucknow. Similarly, the National Brain Research Centre is situated in Manesar. However, the National Botanical Research Institute is actually located in Lucknow, rather than Pune, making that specific geographic pair incorrect in the list.
Q9524. The Shanti Swarup Bhatnagar Prize, one of the highest multidisciplinary science awards in India, is awarded annually by the CSIR. Which of the following is the most appropriate eligibility criterion for this award?
Explanation
The Shanti Swarup Bhatnagar Prize is a prestigious award honoring excellence in various scientific disciplines in India. It is specifically designed to recognize and encourage young scientists who have made outstanding contributions to their respective fields. To be eligible for this award, a researcher must be an Indian citizen or an Overseas Citizen of India under the age of forty-five years.
Q9525. Which of the following options represents the correct chronological order of the first successful flight tests of India’s indigenous missile systems?
Explanation
The development of India’s missile systems followed a distinct timeline. Prithvi-I, a short-range ballistic missile, was first tested in 1988. This was followed by the Agni-I technology demonstrator in 1989. Much later, the BrahMos supersonic cruise missile was successfully tested in 2001. Finally, the Agni-V, an intercontinental-range ballistic missile, conducted its first successful flight test in 2012, marking advanced strategic capability.
Q9526. Four of the following terms belong to the category of Indian space launch vehicles. Identify the odd one out.
Explanation
India’s space programme utilizes various launch vehicles to place payloads into different orbits. ASLV, PSLV, and GSLV are all categories of rockets designed to carry satellites into space. In contrast, INSAT refers to the Indian National Satellite System, which is a series of multi-purpose geostationary satellites used for telecommunications and meteorology. Thus, INSAT is a satellite series, not a launch vehicle.
Q9527. Which of the following statements correctly describes the capability of the Agni-V missile developed by DRDO?
Explanation
The Agni-V is a critical component of India’s strategic nuclear deterrence. It is a three-stage, solid-fueled intercontinental ballistic missile developed indigenously by DRDO. With a designated strike range exceeding 5,000 kilometers, it allows the country to reach targets across vast distances. This capability places India among an elite group of nations possessing advanced long-range missile technology for national defense.
Q9528. Consider the following statements regarding the PARAM 8000 supercomputer:
Statement I: It was designed using a distributed memory parallel architecture.
Statement II: It relied entirely on imported microprocessors designed by the Soviet Union to bypass American sanctions.
Identify the correct statement from the options below.
Statement I: It was designed using a distributed memory parallel architecture.
Statement II: It relied entirely on imported microprocessors designed by the Soviet Union to bypass American sanctions.
Identify the correct statement from the options below.
Explanation
The PARAM 8000 supercomputer utilized a distributed memory parallel architecture, which allowed it to process multiple tasks simultaneously for high efficiency. Contrary to relying on Soviet technology, the project aimed to overcome Western sanctions through indigenous innovation. It used commercially available microprocessors integrated with custom-designed hardware and software, rather than specific Soviet-designed chips, to build a powerful domestic computing system.
Q9529. What was the primary institutional cause for the establishment of Antrix Corporation Limited in 1992?
Explanation
Antrix Corporation Limited was established in 1992 as a wholly government-owned company. Its primary role is to function as the commercial and marketing arm of the Indian Space Research Organisation. By offering satellite launch services, providing satellite data, and marketing space-related technical consultancy, Antrix enables India to compete in the global space market and generate revenue from its indigenous capabilities.
