Q462. Which of the following is NOT true regarding the seals found in the Indus Valley Civilisation?
Explanation
Harappan seals were versatile objects used primarily for trade and administration. While they bear religious iconography, there is no evidence that they were used exclusively by a priestly class for worship. Instead, they were used by merchants to mark their goods and by officials for administrative purposes. Their widespread distribution across different types of buildings suggests a broad functional role.

Explanation
As part of its updated Nationally Determined Contributions under the Paris Agreement, India has committed to achieving 50% cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030. This ambitious target reflects India’s transition toward solar, wind, and other renewable sources. It is a key part of India’s strategy to decouple economic growth from greenhouse gas emissions while ensuring national energy security.
Q466. According to Joule’s law of heating, the heat produced in a resistor is proportional to the:
Explanation
Joule’s law of heating quantifies the thermal energy produced when an electric current passes through a conductor. It states that the heat generated is directly proportional to the square of the current, the resistance of the conductor, and the time for which the current flows. Because of the squared relationship, even a small increase in current leads to a much larger increase in heat.
Q467. Which of the following pottery types is an odd one out regarding the primary ceramic assemblage of Gilund?
Explanation
The ceramic assemblage at Gilund primarily includes Black and Red Ware, Plain Red Ware, and occasionally Painted Grey Ware in later levels. These reflect the site’s Chalcolithic and Iron Age transitions. In contrast, Northern Black Polished Ware is an odd one out, as it is a luxury ceramic characteristic of the much later Urban Revolution, appearing long after the site’s peak.
Q468. The Harappan site of Shortughai, primarily known as a trading post for lapis lazuli, was located in present-day:
Explanation
Shortughai is a unique Harappan site located in the Badakhshan province of northeastern Afghanistan. It was established as a distant trading colony, primarily to control the supply of lapis lazuli, a highly prized blue stone found in the nearby mountains. The presence of Harappan pottery and architecture so far north illustrates the far-reaching economic interests and organized nature of civilization.
Q469. The constitutional provisions contained in Articles 5 to 11 deal primarily with the citizenship of individuals:
Explanation
The citizenship provisions contained in Part II of the Constitution (Articles 5 to 11) were designed only to identify who became a citizen of India at the commencement of the Constitution on January 26, 1950. They do not provide a permanent or comprehensive law for citizenship. Instead, they left the task of creating laws for future acquisition and termination to the Parliament.

Explanation
Mount Blanc is the highest peak in the Alps, reaching an elevation of 4,807 meters. It is located on the border between France and Italy. As part of a major fold mountain range, it was formed by the tectonic collision of the African and Eurasian plates. The mountain is a significant center for mountaineering and provides important glacial water resources for the region.Answer key for these questions
