Q3234. Which of the following is the most appropriate characterization of Maharana Pratap’s military strategy in the decades following Haldighati?
Explanation
Following his defeat at Haldighati, Maharana Pratap adopted a highly effective strategy of guerrilla warfare.

Statement I: The Kachwaha rulers of Amber maintained a deeply antagonistic relationship with the Mughal Empire throughout the 16th and 17th centuries.
Statement II: Raja Man Singh of Amber was a trusted general of Akbar and served as the governor of Bengal, Bihar, and Kabul.

Raja Man Singh, in particular, was one of Akbar’s most trusted and successful generals, serving as governor of major provinces like Bengal and Kabul. This relationship was generally collaborative rather than antagonistic, as Amber benefited significantly from the high ranks and territories granted by the Mughal emperors.

| Disease | Pathogen/Cause |
|---|---|
| A. Tuberculosis | i. Plasmodium species |
| B. Malaria | ii. Salmonella typhi |
| C. Covid-19 | iii. Mycobacterium |
| D. Typhoid | iv. SARS-CoV-2 |

Q3238. The concept of "Paramountcy," established by the British over the Rajput states in the early 19th century, legally meant that:
Explanation
The legal concept of "Paramountcy" gave the British East India Company, and later the British Crown, ultimate authority over the Rajput states. Under this system, the British controlled all external affairs and defense, while the Rajput rulers were recognized as sovereign in their internal administration. This ensured that the states remained loyal to the British Empire while maintaining their traditional social and political structures.

Explanation
Metastasis is the process by which cancer cells break away from the primary tumor and travel through the blood or lymphatic system to form new tumors in other parts of the body. This spread is what makes cancer a particularly dangerous and life-threatening disease. Once a cancer has metastasized, it is often more difficult to treat and requires systemic therapies like chemotherapy rather than localized surgery.
Q3240. What was the primary cause of the failure of the Hurda Conference (1734)?
Explanation
The failure of the Hurda Conference in 1734 can be attributed to the deep-seated mutual suspicions and conflicting interests among the various Rajput rulers. Although they agreed on the need to check Maratha expansion, they could not settle on a unified command or a shared military strategy. This lack of true cooperation and common purpose prevented the formation of an effective alliance, allowing the Marathas to continue their incursions.Answer key for these questions
