Q22. Consider the following statements regarding the Himalayas:
I. The Himalayas are young fold mountains formed by the collision of the Eurasian and Indo-Australian tectonic plates.
II. They represent the highest mountain system in the world.
III. They are characterized by tectonic stability and an absence of seismic activity.
Which of the above statement(s) is/are correct?
I. The Himalayas are young fold mountains formed by the collision of the Eurasian and Indo-Australian tectonic plates.
II. They represent the highest mountain system in the world.
III. They are characterized by tectonic stability and an absence of seismic activity.
Which of the above statement(s) is/are correct?
Explanation
The Himalayas are young fold mountains created by the collision between the Eurasian and Indo- Australian tectonic plates. They comprise the world’s highest peaks, providing a massive physical barrier across Asia. Unlike stable regions, this mountain system is tectonically active, making it highly prone to frequent seismic activities and earthquakes. This geological instability proves that the mountain-building process continues today.
Q23. Consider the following statements regarding economic development:
I. It involves structural, institutional, and qualitative changes in the economy.
II. It is a narrower concept compared to economic growth.
III. It emphasizes equitable distribution of income alongside increased production.
Which of the above statement(s) is/are correct?
I. It involves structural, institutional, and qualitative changes in the economy.
II. It is a narrower concept compared to economic growth.
III. It emphasizes equitable distribution of income alongside increased production.
Which of the above statement(s) is/are correct?
Explanation
Economic development is a comprehensive process involving structural, institutional, and qualitative transformations within a society. It is a broader concept than economic growth, as it emphasizes the equitable distribution of income alongside increased production. While growth tracks output, development ensures that these resources improve human welfare. Therefore, it involves multidimensional changes that go far beyond simple numerical increases in national output.
Q24. What is the fundamental difference between a scientific theory and a scientific law?
Explanation
Scientific laws provide concise descriptions of natural phenomena, often expressed mathematically, to state what happens under specific conditions. Conversely, scientific theories offer comprehensive, evidence-based explanations of how or why these phenomena occur. While laws summarize observations, theories integrate multiple hypotheses and laws to provide a deeper understanding of the underlying mechanisms driving the natural world and its processes.
Q25. In which of the following modern districts of Rajasthan is the Lower Palaeolithic site of Didwana located?
Explanation
Didwana is a globally recognized archaeological site situated in the Nagaur district of Rajasthan. It is famous for yielding an extensive stratigraphic sequence of the Palaeolithic period. Excavations in this region have provided vital clues about environmental changes and human adaptation within the semi-arid landscape of western India, making it a cornerstone for studying the Pleistocene epoch and early hominin behavior.
Q26. The famous bronze statue of the Dancing Girl was discovered at which of the following Harappan sites?
Explanation
The iconic bronze statue known as the Dancing Girl is a masterpiece of the lost-wax casting technique. Discovered in Mohenjo-daro, it depicts a young woman adorned with bangles and a necklace, showcasing advanced metallurgical skills. This artifact provides significant insights into the artistic sensibilities, social life, and sophisticated aesthetic values of the people during the mature Harappan phase.
Q27. Which among the following British initiatives formally rejected the idea of two constituent assemblies and a separate state of Pakistan, though it proposed a scheme that largely satisfied the Muslim League?
Explanation
The Cabinet Mission Plan, sent in 1946, rejected the Muslim League’s demand for two separate Constituent Assemblies and the creation of Pakistan. However, it proposed a unique scheme for the assembly that grouped provinces into three sections. This arrangement provided a level of autonomy to Muslim-majority provinces, which initially persuaded the Muslim League to accept the plan before withdrawing.
Q28. Identify the odd one out among the following mountains based on their mode of formation.
Explanation
Mount Fuji, Mount Kilimanjaro, and Mount Vesuvius are all volcanic mountains formed by the accumulation of erupted materials like lava and ash. In contrast, the Sierra Nevada is a block mountain system created by the vertical displacement of crustal blocks along fault lines. This difference in primary geological origin makes the Sierra Nevada distinct from the others in the group.
Q29. Match List I with List II and select the correct answer using the codes given below:
| Concepts | Characteristics |
|---|---|
| A. Economic Growth | i. Focuses on expanding the richness of human life rather than simply the richness of the economy. |
| B. Economic Development | ii. Emphasizes meeting present needs without compromising future generations’ ability to meet theirs. |
| C. Human Development | iii. A multidimensional process involving major changes in social structures, popular attitudes, and national institutions. |
| D. Sustainable Development | iv. Typically measured as an annual percentage increase in real gross domestic product. |
Explanation
Economic growth refers to annual increases in Gross Domestic Product, serving as a quantitative measure. Economic development involves multidimensional social and institutional changes. Human development focuses specifically on expanding the richness of human life. Sustainable development ensures current needs are met without harming future generations. These concepts collectively illustrate the transition from purely numerical economic metrics to holistic and future-oriented societal progress.
Q30. Consider the following statements regarding the scientific method:
I. Observation often precedes the formulation of a hypothesis.
II. A valid experiment must be reproducible by other independent scientists.
III. If an experiment contradicts a hypothesis, the data must be discarded.
Which of the above statement(s) is/are correct?
I. Observation often precedes the formulation of a hypothesis.
II. A valid experiment must be reproducible by other independent scientists.
III. If an experiment contradicts a hypothesis, the data must be discarded.
Which of the above statement(s) is/are correct?
Explanation
Effective scientific methodology typically starts with careful observation, which then informs the development of a testable hypothesis. For results to gain credibility, the experimental process must be reproducible by others to confirm accuracy. If data contradicts the hypothesis, researchers must refine or replace the hypothesis rather than discard the data, as unexpected results are critical for scientific advancement.Answer key for these questions
