Q91. Determine the correct chronological order of the geological formations studied for Palaeolithic contexts in the Didwana region (oldest to youngest): I. Amarpura Formation II. Jayal Formation III. Didwana Formation Select the correct order:
Explanation
The geological history of the Didwana region is understood through distinct formations. The Jayal formation is the oldest, representing an ancient river system. This is followed by the Amarpura formation, which contains significant Lower Palaeolithic artifacts. The Didwana formation is the youngest, primarily consisting of aeolian sand dunes that provide a record of later climatic fluctuations and human occupation phases.

Q92. Consider the following statements regarding Harappan urban planning: I. Streets generally intersected at right angles. II. Houses were primarily constructed using baked bricks in standardized ratios. III. Doors and windows usually opened onto main streets rather than side lanes. IV. The city was typically divided into a raised citadel and a lower town. V. The drainage system featured manholes at regular intervals for cleaning. Which of the combination of statements given above is incorrect?
Explanation
Harappan urban planning was characterized by a strict grid system and emphasis on privacy. While streets intersected at right angles and baked bricks were standard, the placement of entrances was unique. Doors and windows typically opened onto side lanes rather than the main streets. This design choice, along with sophisticated drainage systems, highlights the advanced architectural planning of these ancient cities.

Q93. Match List I with List II and select the correct answer from the options given below:
Committee of Constituent Assembly
Chairman
A. Union Powers Committee
i. Dr. B. R. Ambedkar
B. Provincial Constitution Committee
ii. Dr. Rajendra Prasad
C. Drafting Committee
iii. Sardar Vallabhbhai Patel
D. Steering Committee
iv. Jawaharlal Nehru
Explanation
Jawaharlal Nehru chaired the Union Powers Committee, which handled the division of authority. Sardar Vallabhbhai Patel led the Provincial Constitution Committee, focusing on the structures of state governments. The Drafting Committee, responsible for writing the actual text of the Constitution, was headed by Dr. B. R. Ambedkar. Finally, Dr. Rajendra Prasad presided over the Steering Committee to manage assembly business.
Q94. What is the primary cause for the formation of a rift valley alongside block mountains?
Explanation
Rift valleys are formed when the Earth’s crust experiences intense tensional forces that cause it to fracture. This geological stretching leads to the downward subsidence of a central block of land between two parallel faults. The resulting sunken valley is often flanked by uplifted block mountains. The Great Rift Valley in Africa is the most prominent global example of this phenomenon.

Q95. Per capita income of a country is calculated by dividing its national income by its:
Explanation
Per capita income is determined by dividing the total national income of a country by its total population. This mathematical average provides a rough estimate of the income available to each individual citizen. While it is a standard metric for comparing economic status across nations, it serves as a mean value that does not reflect how income is distributed among the people.

Q96. Match the concepts in List I with the examples in List II.
Concepts of Motion
Examples/Applications
A. Inertia of rest
i. Swimming in water
B. Inertia of motion
ii. Dust falling from a beaten carpet
C. Third law of motion
iii. Rocket propulsion
D. Conservation of momentum
iv. Athlete running past the finish line
Explanation
Inertia of rest is seen when dust falls from a carpet being beaten. Inertia of motion explains why athletes cannot stop immediately at the finish line. Swimming demonstrates the third law of motion through action-reaction forces in water. Rocket propulsion relies on the conservation of momentum as exhaust gases are ejected. These examples illustrate fundamental physical principles governing moving objects.

Q97. The concept of the "Luni Industry," representing the Middle Palaeolithic culture in Rajasthan, was introduced by which scholar?
Explanation
V.N. Misra introduced the term "Luni Industry" to describe the Middle Palaeolithic culture identified in the Luni river basin of western Rajasthan. This industry is characterized by the use of smaller flake tools such as scrapers and points, often made from fine-grained stones like chert and jasper. His research highlighted the distinct technological and environmental adaptations of Middle Pleistocene human groups.

Q98. Identify the structure that does not belong to the prominent architectural features found at Mohenjo-daro.
Explanation
Mohenjo-daro contains several monumental structures, including the Great Bath, a large pillared hall, and a collegiate building. These suggest a complex social and administrative hierarchy. However, the famous stone signboard, featuring ten large Harappan characters, was discovered at the site of Dholavira in Gujarat. This unique archaeological find is not associated with the major excavations conducted at Mohenjo-daro.

Q99. Identify the incorrect pair regarding the Minor Committees of the Constituent Assembly and their Chairmen:
Explanation
The Functions of the Constituent Assembly Committee was actually chaired by G. V. Mavalankar, who later became the first Speaker of the Lok Sabha. H. C. Mukherjee, on the other hand, served as one of the Vice-Presidents of the Constituent Assembly and was also the Chairman of the Advisory Committee’s Minorities Sub- Committee, rather than the committee dealing with assembly functions.
Q100. A plateau that is entirely or partially enclosed by mountain ranges is geographically termed as:
Explanation
An intermontane plateau is a high-altitude, relatively flat landform that is completely or partially surrounded by mountain ranges. These plateaus are formed during the same tectonic events that uplift the surrounding mountains. The Tibetan Plateau, located between the Himalayas and the Kunlun Mountains, is the most famous example. Such regions often experience unique climatic conditions due to their high elevation.
