Q5512. In the following question, a statement of
Assertion (A) is followed by a statement of
Reason (R). Choose the correct option:
Assertion (A): The Governor of a State having Scheduled Areas is required to submit a report to the President regarding the administration of such areas.
Reason (R): The executive power of the Union extends to giving directions to the State as to the administration of Scheduled Areas.
Assertion (A) is followed by a statement of
Reason (R). Choose the correct option:
Assertion (A): The Governor of a State having Scheduled Areas is required to submit a report to the President regarding the administration of such areas.
Reason (R): The executive power of the Union extends to giving directions to the State as to the administration of Scheduled Areas.
Explanation
Under the Fifth Schedule of the Constitution, the Governor of a state with Scheduled Areas must submit annual reports to the President regarding their administration. Simultaneously, the executive power of the Union extends to directing states on how these areas should be managed. This mechanism ensures central oversight and accountability, prioritizing the welfare and protection of tribal communities within those regions.
Q5513. Identify the odd one out among the practical applications of Raman spectroscopy.
Explanation
Raman spectroscopy is utilized to identify molecular fingerprints in various materials. It is highly effective for determining chemical structures in pharmaceuticals, verifying historical artworks, and detecting specific hazardous substances like narcotics or explosives. However, measuring vehicle speed relies on the Doppler effect of radio or light waves, which is a fundamentally different physical principle than inelastic molecular scattering.
Q5514. Consider the following statements regarding the political consolidation under the Sangama dynasty:
I. Bukka I ended the Madurai Sultanate and incorporated it into the Vijayanagar Empire.
II. Deva Raya II initiated the practice of recruiting Muslim cavalrymen into the Vijayanagar army.
III. The Sangama rulers patronized only Shaivism and persecuted Jain scholars.
Which of the above statement(s) is/are correct?
I. Bukka I ended the Madurai Sultanate and incorporated it into the Vijayanagar Empire.
II. Deva Raya II initiated the practice of recruiting Muslim cavalrymen into the Vijayanagar army.
III. The Sangama rulers patronized only Shaivism and persecuted Jain scholars.
Which of the above statement(s) is/are correct?
Explanation
Bukka I expanded the empire by defeating the Madurai Sultanate, an event famously chronicled in the Madura Vijayam. Deva Raya II recognized the tactical advantage of Muslim cavalry and archers, incorporating them into his forces to counter the Bahmanis. Contrary to claims of persecution, the Sangama rulers generally maintained a policy of religious tolerance, patronizing Shaivism, Vaishnavism, and Jainism.
Q5515. Under the Scheduled Castes and the Scheduled Tribes (Prevention of Atrocities) Act, 1989, which of the following is considered an offence of atrocity?
Explanation
The Scheduled Castes and the Scheduled Tribes Prevention of Atrocities Act, 1989, identifies specific acts of humiliation as criminal offences. Forcing a member of these communities to consume inedible or obnoxious substances is explicitly listed as an atrocity.
Q5516. In Raman scattering, what is the primary cause of the change in wavelength of the scattered light?
Explanation
The shift in wavelength during Raman scattering results from the interaction between incident photons and the vibrational or rotational energy levels of molecules. When a photon collides with a molecule, it may transfer energy to it or gain energy from it. This energy exchange alters the photon’s frequency, creating the distinct spectral lines used in chemical analysis.
Q5517. Which of the following regions was not a major source of territorial conflict between the Sangama rulers of Vijayanagar and the Bahmani Kingdom?
Explanation
The Raichur Doab, the Krishna-Godavari delta and the Konkan were contested between Vijayanagar and the Bahmanis. Marathwada was not a main area of conflict between them, so C is the answer.
Q5518. Consider the following statements regarding the constitutional framework for women empowerment:
Statement I: Article 39(d) of the Constitution directs the State to ensure equal pay for equal work for both men and women.
Statement II: The Maternity Benefit Act was enacted solely to fulfill the fundamental duties outlined in Article 51A.
Which of the following is correct?
Statement I: Article 39(d) of the Constitution directs the State to ensure equal pay for equal work for both men and women.
Statement II: The Maternity Benefit Act was enacted solely to fulfill the fundamental duties outlined in Article 51A.
Which of the following is correct?
Explanation
Article 39(d) of the Constitution is a Directive Principle of State Policy that mandates equal pay for equal work for both genders. The Maternity Benefit Act was enacted to fulfill the objectives of Article 42, which requires the State to ensure just and humane conditions of work and maternity relief. It is not derived from fundamental duties under Article 51A.
Q5519. Which of the following is an exception to the primary areas of research conducted by C.V. Raman during his career?
Explanation
Throughout his illustrious career, C.V. Raman investigated a wide range of physical phenomena. His research encompassed the acoustics of musical instruments, the physiology of human vision, and the magnetic properties of crystals. While he was deeply interested in the natural world, he did not conduct research in agricultural genetics, which was a field led by other specialized biological scientists.
Q5520. Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). Select the correct option.
Assertion (A): Deva Raya II enlisted a large number of Muslim archers and cavalrymen into his army.
Reason (R): He recognized that the Bahmani army’s superiority lay in their cavalry and skilled archery, which he needed to counter effectively.
Assertion (A): Deva Raya II enlisted a large number of Muslim archers and cavalrymen into his army.
Reason (R): He recognized that the Bahmani army’s superiority lay in their cavalry and skilled archery, which he needed to counter effectively.
Explanation
Deva Raya II enlisted many Muslim archers and cavalrymen because the Bahmani army’s strength lay in cavalry and archery, and he needed to match it. The reason explains the assertion.Answer key for these questions
