UPSC 2011 Prelims Questions with Answers

Explanation

A VPN is a technology that creates a secure, encrypted connection(computer network) over a public internet network (such as the internet) to allow remote users to access their organization’s private network securely. It ensures that data transmitted between the user and the organization’s network is protected from interception or unauthorized access. A VPN encrypts the data transmitted between the user’s device and the VPN server. This ensures that even if the data is intercepted it cannot be read by unauthorized parties. They allow users to bypass geo-restrictions and access content that may be blocked in their region (e.g., streaming services, websites, or social media platforms).

Explanation

Statement 1 is correct: One of the key goals of the Look East Policy was to strengthen India’s presence and influence in East and Southeast Asia, aligning with major economies like ASEAN, Japan, and South Korea. It aimed at enhancing trade, investment, defense cooperation, and connectivity in the region.

Statement 2 is incorrect: The end of the Cold War led to a shift in global power dynamics, but the Look East Policy was not specifically aimed at filling a power vacuum. Instead, it was driven by India’s need for economic liberalization, regional integration, and diversification of foreign policy.

Statement 3 is correct: India has deep-rooted cultural and historical links with Southeast and East Asian countries, particularly through Buddhism, Hinduism, and trade routes. The policy is aimed at reviving these traditional ties to strengthen diplomatic and economic partnerships.

Explanation

Statement 1 is incorrect: The Australia Group (AG) is indeed an informal arrangement that aims to prevent the proliferation of chemical and biological weapons. However, the Wassenaar Arrangement (WA) is also an informal group, not a formal OECD body. The Wassenaar Arrangement focuses on the control of conventional arms and dual-use goods and technologies, not chemical or biological weapons.

Statement 2 is incorrect: The Australia Group consists of 42 members (including the USA, European countries, Australia, and Japan). It does not primarily comprise Asian, African, or North American nations. The Wassenaar Arrangement consists of 42 members, mainly from Europe, North America, and some Asian countries (including India, Japan, and South Korea). However, it is not exclusive to European and American continents.

Explanation

Statement 1 is incorrect: The Strait of Malacca is already a deep and navigable waterway between Malaysia and Indonesia and is one of the busiest maritime routes in the world. Deepening the Malacca Strait would not significantly reduce navigation time because ships already use this route effectively. The real challenge is congestion and piracy, not depth.

Statement 2 is correct: The Kra Canal (proposed) would create a shortcut through Thailand’s Kra Isthmus, connecting the Gulf of Thailand (Siam) with the Andaman Sea. This would allow ships to bypass the long detour through the Malacca Strait, reducing both travel time and distance between India and East Asia. However, the canal has not yet been constructed, though discussions and feasibility studies have taken place.

Explanation

Article 51A of part IV-A of the Indian Constitution deals with the Fundamental Duties. These duties are the moral and civic obligations that all citizens of a nation have. To vote in public elections is not a fundamental duty as it is not included in article 51A. List of Fundamental Duties:

Explanation

A rapid rise in the population of algae in an aquatic system is known as an algal bloom, marine bloom, or water bloom. Algal blooms can appear in both marine and freshwater habitats. "Harmful algal blooms (HAB)" are blooms that can affect wildlife or the environment. Harmful Algal Bloom can lead to fish die-offs, cities cutting off water to residents, or states having to close fisheries.

Statement 1 is correct: Estuaries receive nutrient-rich water from rivers which can include agricultural runoff, sewage, and industrial effluents. These nutrients, particularly nitrogen and phosphorus promote the growth of algae causing algal blooms.

Statement 2 is correct: Heavy rainfall during the monsoon season can cause significant runoff from agricultural fields, urban areas, and other land surfaces. This runoff can carry fertilizers, pesticides, and other nutrients into the sea, providing the necessary conditions for algal blooms

Statement 3 is correct: Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients, which again leads to algal blooms.

Explanation

Article 266 further says, No money out of this fund can be issued except in accordance with a parliamentary law. Thus, the authorization for the withdrawal of funds from the Consolidated Fund of India must come from the Parliament of India.

Explanation

For slowing down global warming, carbon sequestration involves the capture and storage of CO. It is captured from the air, industries or power stations and stored permanently underground. This promotes Long-term reserve of CO or forms of carbon to control temperatures. Carbon sequestration aids in lowering the amount of GHGs (due to combustion of fossil fuels) present in the air.

Statement 2 is correct: The photosynthesis by phytoplankton in the oceans is natural carbon sequestration and it is responsible for much of CO2 being moved from lower atmosphere to oceans:

Statements 1 is incorrect: CO is a heavy gas that primarily accumulates in the troposphere and lower stratosphere but does not escape into the outer stratosphere or space. The primary removal mechanisms of CO involve absorption by oceans, photosynthesis by plants, and geological sequestration rather than atmospheric escape. Statements 3 is incorrect: Polar ice caps and glaciers are not a major active carbon sink. Ice trapping does not remove a significant amount of CO from the atmosphere on short time scales. While some CO gets sealed in glaciers but melting due to climate change can release CO back into the atmosphere thereby making this process less effective in long-term carbon storage.

Explanation

The Consolidated Fund of India is the primary fund of the Union Government where all its revenues, including taxes, loans, and other receipts for the conduct of government business, are deposited. According to the Constitution of India, all government spending must be approved by Parliament and drawn from this fund. The accounts of Government are kept in three parts:

1. Consolidated Fund of India

2. Contingency Fund of India

3. Public Account of India
