Q582. Why are dewdrops not formed on a cloudy night?
Explanation
Dew formation occurs when the Earth’s surface cools down sufficiently at night, causing moisture in the air to con-dense into water droplets on cool surfaces. On clear nights, the Earth’s surface loses heat rapidly through a process called radia-tive cooling. This cooling lowers the temperature of surfaces like grass or leaves, leading to the formation of dew as the air reaches its dew point.
Option (b) is correct: On cloudy nights, the situation changes. Clouds act like a blanket, reflecting back the infrared radiation (heat) emitted by the Earth’s surface. This process is known as the greenhouse effect at a smaller scale. Because the heat is trapped, the Earth’s surface doesn’t cool enough for dew to form.
UPSC 2019Polity · Preamble
Q583. In the context of polity, which one of the following would you accept as the most appropriate definition of liberty?
Explanation
Liberty is generally understood not as the absence of restraint or mere freedom to do whatever one likes, but as the freedom to develop one’s full potential within the framework of laws and rights that ensure the same freedom for others. This idea aligns with the concept of positive liberty, which is the ability to act in ways that allow personal and collective growth, while also respecting the freedoms of others.
Exam tip:
Break down the options using two filters: Is it positive or negative in tone? Is it balanced or extreme?
Option A, Sounds reactive and negative — liberty as shield, not as freedom. Also narrow — only about political rulers.
Option B, Feels absolute, like no rules at all(negative tone). That’s not liberty — that’s anarchy. Similarly Option C, disguised as liberty but actually promoting lawlessness(negative tone).
Option D, Balanced + Empowering = Hence, Most appropriate

Q584. Consider the following statements: 1. The United Nations Convention against Corruption (UNCAC) has a ‘Protocol against the Smuggling of Migrants by Land, Sea and Air’. 2. The UNCAC is the ever-first legally binding global anti-corrup-tion instrument. 3. A highlight of the United Nations Convention against Transnational Organized Crime (UNTOC) is the inclusion of a specific chapter aimed at returning assets to their rightful owners from whom they had been taken illicitly. 4. The United Nations Office on Drugs and Crime (UNODC) is mandated by its member States to assist in the implementation of both UNCAC and UNTOC. Which of the statements given above are correct?
Explanation
Statement 1 is incorrect: The Protocol against the Smuggling of Migrants by Land, Sea and Air is not part of the United Nations Convention against Corruption (UNCAC). It is a supplementary protocol to the United Nations Convention against Transnational Organized Crime (UNTOC) adopted in 2000. The UNCAC was adopted in 2003 and focuses specifically on combating corruption and does not include provisions related to migrant smuggling.
Statement 2 is correct: The UNCAC adopted in 2003 is the first legally binding global instrument to combat corruption. It provides a comprehensive framework for preventing and criminalizing corruption, promoting international cooperation, and recovering illicitly acquired assets. It has been ratified by nearly all UN member states.
Statement 3 is incorrect: The UNTOC primarily focuses on combating transnational organized crime, including human trafficking, migrant smuggling, and illicit arms trafficking. It includes provisions for international cooperation and asset recovery but it does not have a specific chapter dedicated to returning assets to their rightful owners. This is a key feature of the UNCAC, which has a detailed chapter (Chapter V) on asset recovery.
Statement 4 is correct: The United Nations Office on Drugs and Crime (UNODC) is responsible for helping countries implement both UNCAC and UNTOC. UNODC provides technical assistance, legal advice, and training to strengthen anti-corruption and anti-crime efforts.

Q590. With reference to land reforms in independent India, which one of the following statements is correct?
Explanation
Land reforms in independent India were primarily aimed at redistributing land to achieve social equity and increase agricultural productivity.
Option (a) is incorrect: Ceiling laws often target individual holdings to prevent landowners from circumventing the laws by splitting land among family members. While some states applied ceilings to family holdings, this was not consistent across India. Example: In Uttar Pradesh, ceiling laws were implemented based on individual holdings, allowing families to distribute land titles among relatives to bypass ceilings. In contrast, states like Kerala applied ceilings based on family holdings.
Option (b) is correct: The primary goal of land reforms in independent India was to redistribute land to landless farmers and promote social justice. This aimed to reduce inequalities in land ownership and improve agricultural productivity.
Option (c) is incorrect: Land reforms primarily focused on redistribution and tenancy reforms, with the aim of promoting food security and subsistence farming rather than the cultivation of cash crops. Example: In West Bengal and Kerala, land reforms led to increased production of rice and staple crops, not cash crops like cotton or sugarcane.
Option (d) is incorrect: Many states provided exemptions to ceiling limits for specific purposes, such as plantations, religious institutions, and educational establishments. Example: Religious and charitable institutions were also exempt in states like Tamil Nadu and Karnataka.
