Q372. What is the main distinguishing feature of Rajasthan’s Banasian (Ahar) Chalcolithic culture compared to the contemporary Harappan civilization?
Explanation
The Banasian or Ahar culture differs significantly from the contemporary Harappan civilization in its social and architectural organization. While the Harappans built highly planned urban centers with advanced drainage, the Ahar people lived in rural settlements. Their houses were constructed using local stone foundations and mud walls, lacking the standardized town planning, grid systems, and baked brick architecture characteristic of Harappans.
Q373. In the context of the decline of the Indus Valley Civilisation, the term Late Harappan Phase refers to:
Explanation
The Late Harappan Phase represents the period following the decline of the great urban centers. During this time, the characteristic features of the civilization, such as the grid system, script, and standardized weights, gradually disappeared. The culture became more localized and rural, with people living in smaller settlements and practicing simplified forms of the earlier Harappan traditions and crafts.
Q374. Which of the following represents the correct sequence of ideals as they are enumerated in the Preamble to the Constitution of India?
Explanation
The Preamble lists the objectives of the Constitution in a specific order: Justice (social, economic, and political), followed by Liberty (of thought, expression, belief, faith, and worship), then Equality (of status and of opportunity), and finally Fraternity (assuring the dignity of the individual and the unity and integrity of the Nation). This sequence outlines the hierarchical progression of constitutional ideals.
Q375. Oases are vital features in desert environments. Which of the following processes predominantly leads to their formation?
Explanation
An oasis is a fertile area in a desert where water is available. They are primarily formed through the process of wind deflation. Constant wind erosion can hollow out a depression in the desert floor. When this depression becomes deep enough to reach the underground water table, water seeps to the surface. This allows vegetation to grow and supports human and animal life.
Q376. The System of Environmental-Economic Accounting (SEEA) is an international statistical standard used to:
Explanation
The System of Environmental-Economic Accounting is an international framework for organizing statistical data on the environment and its relationship with the economy. It allows nations to track resource use, emissions, and the stock of natural assets in a way that is consistent with national accounts. By integrating these datasets, policymakers can better understand the environmental consequences of economic activities.
Q377. Consider the following statements regarding the speed of sound:
I. It is greater in solids than in liquids.
II. It increases with an increase in the temperature of the medium.
III. It can travel through a perfect vacuum.
IV. It is greater in humid air than in dry air.
Which of the above statement(s) is/are correct?
I. It is greater in solids than in liquids.
II. It increases with an increase in the temperature of the medium.
III. It can travel through a perfect vacuum.
IV. It is greater in humid air than in dry air.
Which of the above statement(s) is/are correct?
Explanation
Sound travels fastest in solids due to the close proximity of atoms, and its speed increases with temperature because particles move more quickly. Humid air is less dense than dry air, which actually allows sound to travel faster. Crucially, sound is a mechanical wave and requires a medium to propagate; therefore, it cannot travel through a vacuum, making that statement incorrect.
Q378. The Ochre Coloured Pottery (O.C.P.) tradition in Rajasthan is most closely associated with the metallurgical exploitation of which element?
Explanation
The Ochre Coloured Pottery (O.C.P.) tradition is fundamentally linked to the exploitation of copper resources in Rajasthan. Centered in the Ganeshwar-Jodhpura region, these communities were expert metallurgists who utilized the rich Khetri copper belt. They produced a vast array of copper artifacts, including arrowheads, axes, and fish hooks, which were likely traded with other contemporary cultures, including the Indus Valley.
Q379. Which of the following is NOT an archaeological finding associated with Lothal?
Explanation
Lothal was a vibrant port city with features like a brick dockyard, a warehouse, and a bead-making factory. Fire altars have also been found there, suggesting specific ritual practices. However, the famous Priest-King statue, a small steatite sculpture representing a bearded male figure, was discovered at Mohenjo-daro. It is not associated with the archaeological finds recovered from Lothal.
Q380. Match List I with List II and select the correct answer from the options given below:
| Ideal in Preamble | Source of Inspiration |
|---|---|
| A. Social, Economic and Political Justice | i. Russian Revolution (1917) |
| B. Liberty, Equality and Fraternity | ii. French Revolution (1789-1799) |
| C. Republic | iii. French concept of elected head |
| D. Democratic Socialism | iv. Gandhian and Marxist principles |
Explanation
The ideals of social, economic, and political justice were inspired by the Russian Revolution of 1917. The concepts of liberty, equality, and fraternity originated from the French Revolution. The idea of a ‘Republic’ with an elected head also has French roots. Indian ‘Democratic Socialism’ is a unique blend of Gandhian and Marxist principles, emphasizing social welfare within a democratic framework.Answer key for these questions
