Explanation
The Western Ghats biodiversity hotspot runs along the western coast of India, spanning across Gujarat, Maharashtra, Goa, Karnataka, Tamil Nadu, and Kerala. This mountain range is famous for its unique flora and fauna. Odisha is located on the eastern coast of the Indian peninsula and is not part of the Western Ghats mountain system or its designated ecological hotspot.Assertion (A) and the other as Reason (R):
Assertion (A): The late 18th century witnessed a significant economic decline in Rajputana.
Reason (R): Continuous demands for Chauth and Khandani by Maratha commanders ruined merchants and peasants alike.
Explanation
Economic decline in Rajputana during the late eighteenth century was a direct consequence of relentless Maratha demands. Systematic extractions of Chauth and Khandani drained the financial resources of the states. These financial burdens trickled down, ruining merchants and impoverishing the peasantry. Consequently, the regional economy suffered significantly from the constant transfer of wealth to the Maratha commanders and their armies.I. Varahamihira authored the Brihat Samhita, an encyclopedic work on various subjects including astronomy.
II. The Panchasiddhantika of Varahamihira summarizes five earlier astronomical treatises.
III. The Romaka Siddhanta shows clear evidence of Greek astronomical influence.
IV. Aryabhata provided a scientific explanation for solar and lunar eclipses, rejecting mythological beliefs.
V. Aryabhata stated that the apparent rotation of the heavens is due to the axial rotation of the Earth.
Which of the above statement(s) is/are correct?
Explanation
Ancient Indian astronomy reached a high level of sophistication through the works of scholars like Varahamihira and Aryabhata. These thinkers documented Greek influences, summarized traditional astronomical knowledge, and provided scientific explanations for natural phenomena like eclipses. Aryabhata specifically proposed the rotation of the Earth on its axis, reflecting a transition toward rational and observation-based celestial science.Explanation
The Concurrent List serves as a bridge between central and state legislative powers. It includes subjects where a common national approach is desirable, such as criminal law or education, but allows states to make specific modifications to suit local conditions. This dual authority prevents rigid centralization while ensuring that the legal framework across the country remains relatively consistent for all citizens.I. It aims to hold the increase in the global average temperature to well below 2.0 degrees Celsius above pre-industrial levels.
II. It requires all signatory countries to pursue efforts to limit the temperature increase to 1.5 degrees Celsius.
III. It enforces top-down, legally binding emission reduction targets imposed by the UN on all member states.
IV. It relies on Nationally Determined Contributions (NDCs) submitted by individual countries.
Which of the above statement(s) is/are correct?
Explanation
The Paris Agreement focuses on limiting global temperature increases to well below 2.0 degrees Celsius. It encourages efforts to reach a 1.5-degree limit to minimize severe impacts. Countries submit Nationally Determined Contributions, which are self-defined climate action plans. Unlike earlier treaties, it uses a flexible bottom-up approach rather than imposing top-down, legally binding emission targets on states.Assertion (A): The Western Ghats are classified as a biodiversity hotspot.
Reason (R): They host a high degree of endemism and are subjected to significant threat from human activities.
Explanation
The Western Ghats are a globally recognized biodiversity hotspot because they contain a vast number of species found nowhere else on Earth. This high degree of endemism, coupled with significant environmental threats from human activities, fulfills the essential criteria for hotspot designation. Thus, the reasoning provided accurately explains why this region is classified under this specific international conservation category.| Battle | Year |
|---|---|
| A. Battle of Rajmahal | i. 1761 |
| B. Battle of Bhatwara | ii. 1747 |
| C. Battle of Tunga | iii. 1790 |
| D. Battle of Patan | iv. 1787 |
Explanation
The timeline of Maratha-Rajput conflicts includes the Battle of Rajmahal in 1747 and the Battle of Bhatwara in 1761. Later engagements were the Battle of Tunga in 1787 and the Battle of Patan in 1790. These specific dates mark the phases of Maratha military dominance and the varying attempts by Rajput states to resist their relentless financial and political demands.Explanation
The Sulba Sutras represent the earliest records of Indian geometry and mathematical principles. Their development was driven by the strict ritualistic requirements of the Vedic period, which demanded precise measurements and specific geometric shapes for the construction of sacrificial fire altars. This necessity for accuracy in religious architecture led to the formulation of fundamental mathematical and geometric rules.I. Public Health and Sanitation
II. Trade Unions
III. Banking
IV. Agriculture
V. Forests
Which of the above subject(s) is/are placed strictly in the State List according to the Seventh Schedule?
Explanation
Public health and agriculture are subjects strictly placed within the State List of the Seventh Schedule. While banking is a Union subject, trade unions and forests are included in the Concurrent List. Legislative authority over public health and sanitation allows states to manage local medical services and hygiene, whereas control over agriculture enables states to address regional farming needs and land reforms.Answer key for these questions
