Q9472. Identify the incorrect statement regarding the demographic distribution of social groups in Rajasthan.
Explanation
The distribution of social groups in Rajasthan shows regional concentrations. Ganganagar has the highest percentage of Scheduled Castes, while the Scheduled Tribe population is most concentrated in southern districts like Banswara. Conversely, Bikaner and Nagaur have very low proportions of Scheduled Tribes. Stating that Bikaner has the highest proportion of Scheduled Tribes is factually incorrect according to census data.
Q9473. Given below are two statements, one labeled as
Assertion (A) and the other as Reason (R):
Assertion (A): The peaceful nuclear explosion at Pokhran in 1974 resulted in severe international technology embargoes and sanctions against India.

Assertion (A) and the other as Reason (R):
Assertion (A): The peaceful nuclear explosion at Pokhran in 1974 resulted in severe international technology embargoes and sanctions against India.
Reason (R): These sanctions completely permanently halted India’s indigenous development in the atomic energy and space sectors. In the context of the above statements, which one of the following is correct?
Explanation
After the 1974 Pokhran explosion, India faced technology embargoes, so the assertion is true. The sanctions did not permanently halt its atomic energy and space programmes, so the reason is false.
Q9474. Consider the following statements about Rajasthan’s population density factors:
I. Availability of water resources naturally increases population density in eastern Rajasthan.
II. Harsh climatic conditions and sand dunes result in very low population density in western Rajasthan.
III. The demographic divide year for Rajasthan is universally considered to be 1951.
Which of the above statement(s) is/are incorrect?
I. Availability of water resources naturally increases population density in eastern Rajasthan.
II. Harsh climatic conditions and sand dunes result in very low population density in western Rajasthan.
III. The demographic divide year for Rajasthan is universally considered to be 1951.
Which of the above statement(s) is/are incorrect?
Explanation
Population density in Rajasthan is heavily influenced by geography, with water availability favoring the east and desert conditions limiting the west. Historically, 1921 is recognized as the "Demographic Divide" because it was the only period of negative growth. Stating that 1951 is the universal demographic divide year is incorrect, as 1921 marks the significant transition in the state’s census history.

Q9476. Match the districts in List I with their child sex ratio in 2011 in List II:
Codes:
| Districts | Child Sex Ratio 2011 |
|---|---|
| A. Banswara | i. 924 |
| B. Pratapgarh | ii. 928 |
| C. Bhilwara | iii. 933 |
| D. Udaipur | iv. 934 |
Explanation
Child sex ratios in 2011 were relatively better in the southern tribal belt of Rajasthan. Banswara recorded the highest at nine hundred thirty-four, followed closely by Pratapgarh at nine hundred thirty-three. Bhilwara and Udaipur also showed higher-than-average figures of nine hundred twenty-eight and nine hundred twenty-four respectively. These statistics highlight the better survival rates for girls in these regions.
Q9477. Consider the following statements regarding the growth of the biotechnology and pharmaceutical industry in India:
I. The Department of Biotechnology (DBT) was set up under the Ministry of Science and Technology in 1986.
II. Shantha Biotechnics developed India’s first indigenous recombinant DNA Hepatitis B vaccine.
III. India is currently one of the largest providers of generic medicines globally.
IV. The Indian Patents Act of 1970 recognized product patents in pharmaceuticals, which led to the immediate dominance of generic drugs.
Which of the above statement(s) is/are incorrect?
I. The Department of Biotechnology (DBT) was set up under the Ministry of Science and Technology in 1986.
II. Shantha Biotechnics developed India’s first indigenous recombinant DNA Hepatitis B vaccine.
III. India is currently one of the largest providers of generic medicines globally.
IV. The Indian Patents Act of 1970 recognized product patents in pharmaceuticals, which led to the immediate dominance of generic drugs.
Which of the above statement(s) is/are incorrect?
Explanation
The DBT was set up in 1986 and Shantha Biotechnics made India’s first indigenous Hepatitis B vaccine, and India is a large generic supplier. The Patents Act of 1970 recognised process patents, not product patents, so IV is incorrect.
Q9478. Which district of Rajasthan recorded the lowest decadal population growth rate during 2001- 2011?
Explanation
During the census decade of 2001-2011, Ganganagar district recorded the lowest population growth rate in Rajasthan. The growth was significantly lower than the state average, standing at approximately ten percent. This low rate is often attributed to better awareness, higher agricultural stability, and the successful implementation of family planning measures in this northern district compared to the state’s faster-growing regions.
Q9479. Consider the following statements regarding the Population Policy of Rajasthan:
I. Rajasthan introduced its first state population policy in the year 2000.
II. It aims to stabilize the population primarily by reducing the Total Fertility Rate to replacement levels.

Which of the above statement(s) is/are incorrect?
I. Rajasthan introduced its first state population policy in the year 2000.
II. It aims to stabilize the population primarily by reducing the Total Fertility Rate to replacement levels.
III. Family planning programs in the state have completely eradicated the gender gap in literacy.
IV. The policy emphasizes improving reproductive and child health services.
Which of the above statement(s) is/are incorrect?
Explanation
Rajasthan’s population policy, first introduced in 2000, emphasizes stabilizing growth through reduced fertility and improved health services. While these programs have successfully improved various demographic indicators, they have not yet completely eradicated the gender gap in literacy. That specific goal remains a significant challenge, requiring continued social and educational reforms alongside health-focused population stabilization strategies across the state’s districts.
