I. He played a pivotal role in establishing the Indian Institute of Management (IIM) Ahmedabad.
II. He served as the first Chairman of the Indian Space Research Organisation (ISRO).
III. He was posthumously awarded the Padma Vibhushan.
IV. He was the chief designer of India’s first indigenous supercomputer, PARAM.
Which of the above statement(s) is/are incorrect?
Explanation
Dr. Vikram Sarabhai was a visionary who established numerous institutions, including ISRO and IIM Ahmedabad. His contributions were recognized posthumously with the Padma Vibhushan. However, he was not the designer of the PARAM supercomputer. The development of the PARAM series was led by Dr. Vijay Bhatkar and C-DAC in the late 1980s and early 1990s, long after Sarabhai’s death in 1971.
Q9543. Which of the following is NOT a demographic trend observed in Rajasthan between the 2001 and 2011 censuses?
Explanation
Between 2001 and 2011, Rajasthan experienced several demographic shifts, including a decline in growth rates and a slight rise in the overall sex ratio. However, one negative trend was the significant decline in the child sex ratio, which dropped from nine hundred nine to eight hundred eighty-eight. This indicates that gender imbalances at birth became more severe during that decade, contrary to any improvement.
Q9544. Apsara, the first nuclear research reactor in India and Asia, reached criticality in 1956. Which country provided technical assistance and the initial supply of enriched uranium fuel for Apsara?
Explanation
Apsara, the first nuclear research reactor in Asia, became critical in 1956 at the Trombay facility. This project was a major milestone for India’s atomic programme. While the reactor was designed and built indigenously by Indian scientists, the United Kingdom provided the necessary technical assistance and the initial supply of enriched uranium fuel required to operate the pool-type reactor successfully.
Q9545. Identify the incorrect statement regarding the rural and urban child sex ratio in Rajasthan (2011 Census).
Explanation
Data from the 2011 Census shows that the child sex ratio is higher in rural Rajasthan than in urban areas. Specifically, the rural child sex ratio was recorded at eight hundred ninety-two, while the urban ratio was lower at eight hundred seventy-four. This indicates that gender bias and related issues affecting the survival of girl children are currently more pronounced in the state’s urban environments.
Q9546. Identify the correct pair matching the prominent IT/Technology hub in India with its widely recognized colloquial title or specific software park establishment.
Explanation
Several Indian cities are renowned as major technology hubs. Hyderabad is famously associated with HITEC City, a major IT and business district often colloquially referred to as Cyberabad. In contrast, Bangalore is widely known as the Silicon Valley of India and Electronic City, while Pune is also a significant software hub. Matching Hyderabad with HITEC City correctly identifies a specific regional development project.
Q9547. As the current demographic dividend phase eventually passes over the next few decades, Rajasthan will predominantly face the economic and social challenge of:
Explanation
As the current demographic dividend in Rajasthan eventually ends, the age structure will shift. As birth rates continue to fall and life expectancy increases, the proportion of elderly people in the population will grow. This will eventually lead to a higher old-age dependency ratio, creating new challenges for the state’s healthcare system and social security programs aimed at supporting a larger senior population.
Q9548. Consider the following statements regarding India’s nuclear tests:
Statement I: The Pokhran-I test in 1974 was officially characterized by the Indian government as a "peaceful nuclear explosion" (PNE).
Statement II: The Pokhran-II tests in 1998 were explicitly declared as weaponized tests, establishing India as a state possessing nuclear weapons.
Identify the correct statement from the options below.
Statement I: The Pokhran-I test in 1974 was officially characterized by the Indian government as a "peaceful nuclear explosion" (PNE).
Statement II: The Pokhran-II tests in 1998 were explicitly declared as weaponized tests, establishing India as a state possessing nuclear weapons.
Identify the correct statement from the options below.
Explanation
India’s approach to nuclear testing evolved significantly over time. The 1974 test was officially described as a peaceful nuclear explosion to emphasize its non-military intent. In contrast, the 1998 tests were explicitly declared by the government as weaponized detonations. These tests were intended to establish a credible minimum nuclear deterrent, formally declaring India’s status as a state possessing nuclear weapons to the world.
Q9549. What is the absolute difference between the population density of India and Rajasthan as per the 2011 Census?
Explanation
In 2011, the population density of India was recorded at three hundred eighty-two persons per square kilometer. During the same period, Rajasthan’s population density was found to be exactly two hundred. Therefore, the absolute difference between the national and state densities is one hundred eighty-two. This gap reflects Rajasthan’s vast land area, much of which is desert, compared to its total population size.
Q9550. Given below are two statements:
Statement I: The Total Fertility Rate (TFR) of Rajasthan has been continuously declining over the last two decades.
Statement II: Enhanced female literacy, delayed marriages, and family planning awareness have contributed to this decline.
Which of the following is correct?
Statement I: The Total Fertility Rate (TFR) of Rajasthan has been continuously declining over the last two decades.
Statement II: Enhanced female literacy, delayed marriages, and family planning awareness have contributed to this decline.
Which of the following is correct?
Explanation
Rajasthan has seen a consistent decline in its Total Fertility Rate over the past two decades. This trend is driven by several factors, including better access to female education and increased awareness of family planning methods. Furthermore, as social norms change, the average age of marriage has risen, which naturally contributes to lower fertility levels and helps the state move toward population stabilization goals.Answer key for these questions
