Explanation

Indian Muslims were generally not attracted to the Extremist movement because of the movement’s emphasis on Hindu symbolism, rituals, and historical references. The extremists believed in sacrificing everything including life for the cause of the motherland. They tried to instill self respect and patriotism in the people by invoking past heroes like Ashoka, Shivaji, Maharana Pratap, and this approach alienated many Muslims who felt that their religious and cultural identity was not adequately represented or respected.

Explanation

Option (c) is correct: The correct sequence of the different layers of the atmosphere from the surface of the Earth upwards is: Troposphere Stratosphere Mesosphere Ionosphere Troposphere: This is the lowest layer of the atmosphere, extending from the Earth’s surface up to about 8-15 km. It contains most of the Earth’s weather systems and clouds. Stratosphere: Above the troposphere, this layer extends from around 15 km to 50 km. It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation. Mesosphere: Above the stratosphere, the mesosphere stretches from 50 km to 85 km. It is the layer where meteors burn up upon entry into the Earth’s atmosphere. Ionosphere: This is not a distinct layer like the others but rather a region of the atmosphere (spanning from about 60 km to 1,000 km) where ionization of gases occurs. The ionosphere overlaps with the thermosphere and exosphere.

Explanation

The climate data provided, with moderate temperatures and distinct seasonal rainfall patterns, is more in line with the China-type climate found in parts of Eastern Asia. The temperature gradually increases from 3.9°C in January to 27.8°C in July and then decreases towards December. This shows warm summers and cool winters, which is characteristic of the China-type climate, where summers are typically hot and humid and winters are cold and dry.

Explanation

Option (d) is correct: The 1997 Indonesian forest fires were primarily caused by human activities like slash-and-burn agriculture to clear land for plantations, particularly for palm oil production. These fires escalated due to a lack of effective forest management practises. Options (a), (b) and (c) are incorrect:

The greenhouse effect refers to the trapping of heat in the Earth’s atmosphere by greenhouse gases, leading to global warming. While global warming can influence climate patterns, there is no direct evidence linking the greenhouse effect as the immediate cause of the 1997 fires. The ozone layer protects the Earth from harmful ultraviolet radiation. Its depletion is primarily associated with increased UV exposure. Ozone layer depletion does not have a direct connection to forest fires, including those in Indonesia in 1997. El Niño is a climatic phenomenon characterized by the warming of sea surface temperatures in the central and eastern Pacific Ocean, leading to significant weather changes globally. But it is not directly associated with Indonesian forest fires.

Explanation

Sohgaura copper-plate inscription is among the earliest records highlighting the Mauryan state’s concern for preserving food grains during crises. Issued during the Mauryan period, it details a directive for famine relief by storing grains, showcasing a significant step in disaster preparedness by the state. This inscription reflects the Mauryan administrative foresight in dealing with natural calamities and highlights the organized approach of the empire. Options (b), (c) and (d) are incorrect:

Rummindei Pillar Edict of Ashoka is associated with Ashoka’s spread of Dhamma, focusing on moral and ethical governance rather than food grain preservation. Prayaga-prasasti is an inscription that commemorates the achievements of Emperor Samudragupta. It is a eulogy that highlights the military and political prowess of the Gupta dynasty. The Mehrauli Pillar inscription of Chandragupta II primarily commemorates victories and royal patronage rather than providing instructions for crisis management or food grain preservation.

Explanation

Pair 1 is correctly matched: Lothal, located in present-day Gujarat, was a major port city of the Indus Valley Civilization. It is renowned for its well-planned dockyard, which is considered one of the earliest known examples of a dockyard in the world, indicating the importance of maritime trade.

Pair 2 is correctly matched: Sarnath is where Gautama Buddha delivered his first sermon, marking the beginning of his teachings on the Middle Path.

Pair 3 is incorrectly matched: The Lion Capital of Ashoka is not associated with Rajgir but was found at Sarnath. The Lion Capital of Ashoka is a famous sculpture from the Mauryan period and is now the national emblem of India.

Pair 4 is correctly matched: Nalanda was a renowned center of Buddhist learning, attracting scholars from across Asia. Nalanda University (Bihar) was one of the greatest centers of Buddhist learning in ancient India, flourishing under the Gupta and Pala dynasties. It attracted scholars from across Asia, including China, Korea, and Tibet.

Explanation

The correct order of development (from oldest to newest):

Urban Culture arose with the Indus Valley Civilization (~2600 BCE), marking the emergence of planned urban centers.(4) Iron Plough usage began around the 1st millennium BCE, enhancing agricultural output.(3) Punch-marked Silver Coins started circulating by the 6th century BCE as early currency.(2) Gold Coins were introduced during the Kushan period, establishing high-value currency standards.(1)

Explanation

As direct descendants of Tamerlane, the Mughals of India considered Central Asia their true home and ancestral domain and thus desired to recover their ancestral lands. Also, the areas of Kandahar, Balkh, and Badakhshan were strategically important for the Mughal Empire due to their proximity to the borders of the Safavid Empire. Assertion (A) is correct: Dara Sikoh, the son of Shah Jahan, was sent on a military expedition to Balkh, Badakhshan, and Kandahar. These missions aimed to consolidate Mughal influence in these strategically important regions. Reason (R) is incorrect: Dara Shikoh’s expedition to the Middle east failed despite the use of a large army and advanced Mughal artillery. The campaign did not achieve its goals, and the Mughals suffered significant setbacks during Shah Jahan’s reign, including the permanent loss of Kandahar to the Safavids, weakening their influence in the region.

Explanation

The loss of Kandahar was a significant setback for the Mughal Empire due to its strategic importance. It was located in present-day Afghanistan and served as a vital buffer zone between the Mughals and the Safavid Empire, protecting the western frontier. Kandahar was also a key strategic stronghold, controlling trade and military routes with Central Asia and the Middle East. Its fortifications were crucial for projecting Mughal power into regions like Balkh, Badakhshan, and Herat. Losing Kandahar weakened the Mughal position in the northwest.

Explanation

Option (a) is correct: Red tides occur due to the excessive growth of dinoflagellates, which are single-celled organisms containing pigments that cause the water to appear reddish or brownish. These blooms can be found in estuaries, coastal areas, and even open ocean waters. Red tides can be dangerous to marine life and humans due to the toxins produced by the dinoflagellates, which can contaminate seafood and pose health risks when consumed.

Option (b), (c) and (d) are incorrect:

Sea tides refers to the regular rise and fall of sea levels due to gravitational forces exerted by the moon and the sun, not to algal blooms. Black tides are typically associated with oil spills in marine environments, leading to a dark discoloration of the water. Sea flowers is not a standard term used in marine science to describe algal blooms.
