Question : Comprehension:

Read the given passage carefully and answer the questions that follow.
Mountains occupy about a quarter of the Earth’s land, harbour most of its biodiversity hotspots, and supply fresh water to an estimated half of humanity. Present on every continent, mountains include a multitude of ecosystems holding many unique species, such as snow leopards and mountain gorillas. They are also home to great cultural diversity among people who have adapted to the challenges of mountain life. Their special traditions and breath-taking scenery attract ever-growing numbers of tourists.
Mountain regions are particularly sensitive to degradation from both human pressures and climate change. Steep slopes mean the clearing of forest for farming, settlements, or infrastructure, which can cause serious soil erosion as well as the loss of habitat. Erosion and pollution harm the quality of the water flowing downstream. Climate change threatens the quantity and timing of water supplies to farms, cities, industry and power stations. Fast-rising temperatures are forcing mountain species, ecosystems and the people that depend on them to adapt or migrate.

Question : Comprehension:
Read the passage carefully and answer the questions that follow.
India's favourable demographic trends, which have increased the workforce's percentage of the overall population, have paved the way for a significant middle-class expansion. A big population bulge emerging from absolute poverty and set to reach the middle class would generate new dynamics. In India, over 55 percent of the population is predicted to reach the middle class. In reality, because India's demographics are significantly younger than China and the United States, the country's middle class might be the world's largest (in terms of population) by 2025.
It is no exaggeration to argue that future growth will be reliant on the increasing middle class and that the middle class's development will be reliant on growth. Growth has been fuelled by both private consumption and saving, both of which are fuelled by the middle class. India's private consumption accounts for over 60% of the country's GDP, while private consumption growth has contributed to 70% of the country's growth since 2000.
Even though China's middle class is now greater than India's, private spending in the former accounts for a lesser share of growth. In contrast to the United States, where domestic savings are dropping and the country borrows excess funds from outside to invest and expand, India's domestic savings and investments are increasing and funding investments. The emergence of the middle class is anticipated to coincide with a transition away from large-scale informality, which now characterises much of the services and industrial sectors, and toward more formal, wage-earning, and medium-scale firms. Technological advancements will spread at a faster rate. Cities will expand as job possibilities concentrate on them. If there is enough movement across states and from rural to urban regions, the population increase will be more evenly distributed.
