Q9512. Which of the following districts recorded the lowest child sex ratio in Rajasthan according to the 2011 Census?
Explanation
Jhunjhunu district recorded the lowest child sex ratio in Rajasthan during the 2011 Census. The figure was significantly lower than the state average, reflecting deep-seated social issues and the misuse of medical technology for gender selection. This trend is particularly concerning given the district’s relatively high literacy rates, suggesting that education alone has not been sufficient to overcome traditional preferences for male children.
Q9513. Consider the following statements regarding the Pokhran-II nuclear tests:
I. The tests were conducted over three days in May 1998.
II. The operation involved the testing of a thermonuclear device.
III. Following the successful tests, India immediately signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
IV. The date of the first test, May 11, was officially declared as National Technology Day in India.
Which of the above statement(s) is/are correct?
I. The tests were conducted over three days in May 1998.
II. The operation involved the testing of a thermonuclear device.
III. Following the successful tests, India immediately signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
IV. The date of the first test, May 11, was officially declared as National Technology Day in India.
Which of the above statement(s) is/are correct?
Explanation
The Pokhran-II tests in May 1998 involved multiple detonations, including a thermonuclear device, over several days. Following these successful tests, the government declared May 11 as National Technology Day to celebrate scientific achievement. Crucially, India did not sign the Comprehensive Nuclear-Test-Ban Treaty afterward, maintaining its strategic autonomy and refusing to accept what it considered discriminatory international nuclear non-proliferation regimes.
Q9514. Based on recent decadal growth trends, Rajasthan is currently transitioning through which phase of the demographic transition model?
Explanation
Rajasthan is currently in a phase of demographic transition where both fertility and mortality rates are on a downward trend. While the population is still increasing, the rate of growth has slowed compared to the late twentieth century. This transition is typical for developing regions as they improve healthcare and education, eventually leading toward a more stable and balanced population structure over time.
Q9515. Although established before independence, the Indian Institute of Science (IISc) Bangalore saw significant expansion in its aerospace and scientific research capabilities post-independence under the directorship of which prominent space scientist?
Explanation
The Indian Institute of Science in Bangalore saw a major transformation in its aerospace and atmospheric research capabilities after independence. This expansion occurred significantly under the leadership of Satish Dhawan, who served as the Institute’s director. His dual role as the head of ISRO and IISc helped integrate academic research with the practical requirements of the burgeoning national space programmes.
Q9516. Consider the following demographic indicators comparing India and Rajasthan as per the 2011 Census:
I. Rajasthan’s decadal growth rate (21.3%) is higher than India’s (17.7%).
II. Rajasthan’s population density (200) is lower than India’s (382).
III. Rajasthan’s overall literacy (66.1%) is lower than India’s (73.0%).
IV. Rajasthan’s sex ratio (928) is lower than India’s (943).
V. Rajasthan’s child sex ratio (888) is lower than India’s (919).
Which of the combinations of the above statements is correct?
I. Rajasthan’s decadal growth rate (21.3%) is higher than India’s (17.7%).
II. Rajasthan’s population density (200) is lower than India’s (382).
III. Rajasthan’s overall literacy (66.1%) is lower than India’s (73.0%).
IV. Rajasthan’s sex ratio (928) is lower than India’s (943).
V. Rajasthan’s child sex ratio (888) is lower than India’s (919).
Which of the combinations of the above statements is correct?
Explanation
Comparing Rajasthan and India based on 2011 figures reveals distinct demographic variations. Rajasthan exhibits a higher decadal growth rate and lower population density compared to national averages. Furthermore, the state lags in overall literacy and the overall sex ratio, while the child sex ratio remains significantly lower than the nationwide figure, illustrating the diverse developmental challenges present across the state’s various districts.
Q9517. The Indian biotechnology sector has made massive strides in vaccine manufacturing. Which of the following is NOT an indigenous Indian biopharmaceutical company known for vaccine development or manufacturing?
Explanation
India’s biotechnology sector is home to several major indigenous firms specializing in vaccine production. Companies like the Serum Institute of India and Bharat Biotech have achieved global recognition for their manufacturing capacity and development of domestic vaccines. While Pfizer has a significant presence in India, it is a multinational corporation headquartered in the United States, not an indigenous Indian pharmaceutical company.
Q9518. What is the approximate percentage of the Scheduled Tribe (ST) population in Rajasthan as per the 2011 Census?
Explanation
According to the 2011 Census, the Scheduled Tribe population makes up approximately thirteen point five percent of Rajasthan’s total population. These communities are primarily concentrated in the southern districts of the state, such as Banswara and Dungarpur. This demographic data is vital for ensuring proper representation and the effective delivery of developmental programs aimed at the socio-economic upliftment of tribal groups.
Q9519. Match the series of indigenous supercomputers in List I with the respective Indian organizations that developed them in List II.
| Supercomputer Series | Developing Organization |
|---|---|
| A. PARAM series | i. Bhabha Atomic Research Centre (BARC) |
| B. Anupam series | ii. National Aerospace Laboratories (NAL) |
| C. PACE series | iii. Defence Research and Development Organisation (DRDO) |
| D. Flosolver | iv. Centre for Development of Advanced Computing (C-DAC) |
Explanation
Different Indian organizations developed supercomputers to meet specialized needs. C-DAC produced the PARAM series for general-purpose high-performance computing. The Bhabha Atomic Research Centre developed the Anupam series for nuclear research. DRDO created the PACE series for defense and aerodynamic simulations, while the National Aerospace Laboratories built the Flosolver specifically to solve complex fluid dynamics problems relevant to aviation and meteorological studies.
Q9520. Given below are two statements:
Statement I: The working-age population percentage is gradually increasing in Rajasthan.
Statement II: This shift naturally reduces the overall demographic dependency ratio.
Which of the following is correct?
Statement I: The working-age population percentage is gradually increasing in Rajasthan.
Statement II: This shift naturally reduces the overall demographic dependency ratio.
Which of the following is correct?
Explanation
Rajasthan is experiencing a shift in its age structure, with a growing percentage of people in the fifteen to sixty-four age bracket. This increase in the working-age population naturally leads to a decrease in the overall dependency ratio, as there are more potential earners relative to children and the elderly. This shift provides a unique opportunity for economic acceleration if managed with proper policies.Answer key for these questions
