Q5743. Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). Select the correct option.
Assertion (A): Sultan Zain-ul-Abidin is often referred to as the ‘Akbar of Kashmir’.
Reason (R): He abolished the Jizya tax, prohibited cow slaughter, and extended liberal patronage to both Sanskrit and Persian scholars.
Assertion (A): Sultan Zain-ul-Abidin is often referred to as the ‘Akbar of Kashmir’.
Reason (R): He abolished the Jizya tax, prohibited cow slaughter, and extended liberal patronage to both Sanskrit and Persian scholars.
Explanation
Sultan Zain-ul-Abidin is often compared to the Mughal Emperor Akbar because of his remarkably progressive and liberal policies. He was one of the first Muslim rulers to abolish the Jizya tax and prohibit the slaughter of cows out of respect for the local population. His patronage of both Persian and Sanskrit literature, and his inclusion of diverse communities in high administrative roles, mirrored the inclusive statecraft later adopted by Akbar.

| A. Jodhpur | i. Cold desert climate |
| B. Thiruvananthapuram | ii. Arid / Semi-arid climate |
| C. Delhi | iii. Extreme continental climate |
| D. Leh | iv. Equable maritime climate |
Explanation
Jodhpur features an arid or semi-arid climate typical of the Thar desert region. Thiruvananthapuram has an equable maritime climate due to its coastal location. Delhi experiences an extreme continental climate with very hot summers and cold winters. Leh, situated in the high-altitude rain shadow of the Himalayas, possesses a cold desert climate with very low annual precipitation.
Q5745. Consider the following statements about Jagadish Chandra Bose:
I. He founded the Bose Institute in Calcutta in 1917.
II. He was a pioneer of Bengali science fiction.
III. He firmly believed that there is no distinct boundary between the living and the non-living.
IV. His research in plant physiology was initially met with resistance by orthodox Western biologists.
V. He exclusively published his research in Indian journals to avoid Western scrutiny.
Which of the above statement(s) is/are correct?
I. He founded the Bose Institute in Calcutta in 1917.
II. He was a pioneer of Bengali science fiction.
III. He firmly believed that there is no distinct boundary between the living and the non-living.
IV. His research in plant physiology was initially met with resistance by orthodox Western biologists.
V. He exclusively published his research in Indian journals to avoid Western scrutiny.
Which of the above statement(s) is/are correct?

Q5746. Identify the odd one out among the following historical structures, based on their categorization as astronomical observatories built by Sawai Jai Singh II.
Explanation
Sawai Jai Singh II built observatories at Jaipur, Delhi, Ujjain, Varanasi and Mathura. There is no Jantar Mantar of his at Udaipur, so it is the odd one out.
Q5747. Which of the following statements regarding the Kashmir Sultanate under Zain-ul-Abidin is incorrect?
Explanation
The statement that Zain-ul-Abidin persecuted Kashmiri Pandits is historically incorrect; he was actually their great protector and benefactor. He ended the era of religious oppression, allowed the reconstruction of temples, and actively encouraged the return of the Pandit community. His other contributions, such as translating classical texts, introducing new crafts like paper-making, and building the island of Zaina Lanka, are well-documented and celebrated aspects of his rule.
Q5748. Identify the odd one out among the following regarding the characteristics of the Cold Weather Season in India.
Explanation
The cold weather season in India is generally characterized by high pressure over the northern plains, offshore winds blowing from land to sea, and pleasant weather with clear skies. While some regions like the northwest receive rain from Western Disturbances and the southeast from the Northeast monsoon, heavy rainfall is not a general characteristic across the central Indian plateau during winter.
Q5749. The Saha ionization equation, formulated by Meghnad Saha, is fundamentally applied in astrophysics to determine which of the following?
Explanation
The Saha ionization equation is a fundamental tool in astrophysics that relates the ionization state of an element to the temperature and pressure of a gas. By applying this equation to the observed spectral lines of stars, astronomers can determine their surface temperatures and chemical compositions. This breakthrough allowed for the quantitative physical classification of stars based on their actual properties.
Q5750. Consider the following statements regarding Zain-ul-Abidin’s contributions to Kashmir:
I. He developed a vast network of canals for irrigation.
II. He revived the shawl-making industry by inviting weavers from Central Asia.
III. He strictly enforced Islamic criminal law on all his subjects, regardless of religion.
