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 per cent 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.
Despite the fact that 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.

Question : Comprehension: Read the given passage and answer the questions that follow. Climate policy must now put health at the centre and promote climate change mitigation policies that bring health benefits simultaneously. Health-focused climate policy would help bring about a planet that has cleaner air, more abundant and safer freshwater and food, more effective and fairer health and social protection systems, and, as a result, healthier people. Investments in clean energy will yield health gains that repay those investments twice over. There are proven interventions able to reduce emissions of short-lived climate pollutants, for instance, applying higher standards for vehicle emissions, which have been calculated to save approximately 2.4 million lives per year, through improved air quality and reduce global warming by about 0.5°C by 2050. The cost of renewable sources of energy has decreased significantly in the last few years, and solar energy is now cheaper than coal or gas in most major economies. Question: Which of the following represents the structure of the passage?
Option 1: Chronology
Option 2: Critique
Option 3: Problem-solution
Option 4: Definition
Correct Answer: Problem-solution
Solution : The correct answer is the third option
The structure of the passage is problem-solution. It discusses the importance of integrating health into climate policy and outlines solutions or interventions to achieve that goal by adopting health-focused climate change mitigation strategies.
