Q5482. In the context of Rajasthan’s temple architecture, the Panchayatana layout refers to which of the following arrangements?
Explanation
The Panchayatana layout is a classical temple plan where the main shrine occupies the center of a rectangular platform. Four smaller subsidiary shrines are situated at each corner, creating a quincunx arrangement. This structural design symbolizes a cosmic hierarchy and is common in Nagara architecture, providing a balanced and spiritually significant environment for the primary deity and associated divinities.
Q5483. Which of the following statements correctly defines the initial purpose behind the foundation of the Vijayanagar Empire by Harihara and Bukka in 1336 CE?
Explanation
The foundation of the Vijayanagar Empire in 1336 CE was fundamentally driven by the desire to resist the southward expansion of the Delhi Sultanate. It aimed to preserve and defend Hindu socio-cultural traditions and religious institutions from external pressures. Under the guidance of sage Vidyaranya, the empire emerged as a powerful bulwark for southern Indian political and cultural sovereignty.
Q5484. Which of the following statements regarding the independence of the Election Commission is incorrect?
Explanation
While the Constitution provides security of tenure and ensures service conditions are not varied to the disadvantage of the Chief Election Commissioner, it does not explicitly debar retiring commissioners from further government appointments. This omission is often cited as a weakness in the framework intended to safeguard the commission’s absolute independence. Other safeguards include the removal process for the Chief Election Commissioner and the requirement of his recommendation for the removal of other commissioners. However, the lack of a post-retirement bar distinguishes it from bodies like the Union Public Service Commission.
Q5485. Read the following statements regarding the role of the Himalayas in shaping India’s climate.
Statement I: The Himalayas prevent the cold winds of Central Asia from entering the Indian subcontinent.
Statement II: The Himalayas force the moisture-laden Southwest monsoon winds to shed their rainfall in India.
Statement I: The Himalayas prevent the cold winds of Central Asia from entering the Indian subcontinent.
Statement II: The Himalayas force the moisture-laden Southwest monsoon winds to shed their rainfall in India.
Explanation
The Himalayan range acts as a critical climatic barrier for India. It effectively blocks frigid, bone-dry winds from Central Asia during winter, maintaining warmer temperatures in the subcontinent. Additionally, the mountains force moisture-laden southwest monsoon winds to rise and precipitate, ensuring vital rainfall across northern India and preventing the moisture from escaping northward.
Q5486. Which of the following is the primary justification for the implementation of the reservation policy in India?
Explanation
The primary justification for India’s reservation policy is the pursuit of substantive equality and social justice. It aims to address centuries of historical disadvantages, systemic exclusion, and social discrimination faced by marginalized communities like Scheduled Castes and Scheduled Tribes. By providing quotas in education and employment, the State seeks to ensure level playing fields and equitable representation.
Q5487. The Raman Effect demonstrates which specific type of scattering when monochromatic light passes through a transparent medium?
Explanation
The Raman Effect specifically refers to the inelastic scattering of photons. When monochromatic light interacts with molecules, most photons scatter elastically, maintaining their frequency. However, a minute portion exchanges energy with molecular vibrations, resulting in shifted frequencies. This shift provides a unique spectral fingerprint, allowing researchers to identify the specific chemical bonds and structures within a substance.
Q5488. Identify the incorrect statement regarding the Dilwara Jain Temples at Mount Abu.
Explanation
The Luna Vasahi temple, dedicated to Neminath, was actually constructed in the thirteenth century, specifically in twelve hundred and thirty. It was commissioned by the ministers Vastupala and Tejapala under the patronage of the Vaghela dynasty.

Q5490. Consider the following statements regarding the appointment and removal of the Chief Election Commissioner (CEC):
Statement I: The CEC is appointed by the President of India.
Statement II: The CEC can be removed from office in the same manner and on the same grounds as a judge of the Supreme Court.
Which of the following statement(s) is/are correct?
Statement I: The CEC is appointed by the President of India.
Statement II: The CEC can be removed from office in the same manner and on the same grounds as a judge of the Supreme Court.
Which of the following statement(s) is/are correct?
Explanation
The President of India appoints the Chief Election Commissioner. To safeguard the office from executive interference, the removal process is stringent. The commissioner can only be removed from office in a manner and on grounds identical to a Supreme Court judge, which requires a special majority in both houses of Parliament. This constitutional protection ensures that the head of the election machinery can function without fear of arbitrary dismissal by the ruling party. The grounds for removal are limited to proved misbehavior or incapacity, mirroring the high standards set for the senior judiciary.Answer key for these questions
