UPSC 2020Ancient History · History of Mauryan Age
Q481. Who among the following rulers advised his subjects through this inscription? "Whosoever praises his religious sect or blames other sects out of excessive devotion to his own sect, with the view of glorifying his own sect, he rather injures his own sect very severely."
Explanation
Ashoka’s religious philosophy evolved from a belief in traditional Hindu practices to the adoption of Buddhism, emphasizing non-violence (ahimsa), compassion, and moral conduct. His Edicts reflect his commitment to dharma, promoting tolerance, welfare, and ethical governance. In Major Rock Edicts 7 and 12, Ashoka explicitly advocates for religious tolerance and the coexistence of all religions. He emphasized that all ascetics (spiritual teachers) should be honored, irrespective of their faith, and that people should respect each other’s beliefs. These edicts reflect Ashoka’s commitment to dhamma (righteousness), which promoted peaceful co-existence.

Q482. Indigo cultivation in India declined by the beginning of the 20th century because of
Explanation
One of the major factors in the decline of indigo cultivation was the invention of synthetic dyes in the 19th century. This breakthrough led to the development of a wide range of synthetic dyes that were cheaper, easier to produce, and more effective than natural indigo. By the 1880s, synthetic dyes became widely available, reducing the global demand for natural indigo.
Exam tip:
Think about what causes a widespread decline in a commercial cash crop. Not a local protest(A). Not just moral opposition(C). You need a market-based, structural reason that impacts the entire economic viability of the crop. Option B aligns most closely with this.
UPSC 2020Modern History · Peasant and Tribal Movements
Q483. With reference to the history of India, "Ulgulan" or the Great Tumult is the description of which of the following events?
Explanation
The Munda Rebellion (1899-1900), led by Birsa Munda, was a major tribal uprising in Chotanagpur (now Jharkhand), known as Ulgulan ("The Great Tumult"). It opposed the zamindari system (introduced in 1874), which replaced the traditional Khuntkari system(land belonged collectively to the Munda clans), creating landlords (zamindars) and tenants (ryots). This led to heavy taxation, exploitation by moneylenders, and forced labor (Beth Begari). Birsa Munda mobilized tribals against British rule and earned the title ‘Dharti Abba’ (Earth Father). The revolt was ultimately suppressed, and Birsa Munda died in prison in 1900.
UPSC 2020Geography · Climatology
Q484. Consider the following statements: 1. Jet streams occur in the Northern Hemisphere only. 2. Only some cyclones develop an eye. 3. The temperature inside the eye of a cyclone is nearly 10°C less than that of the surroundings. Which of the statements given above is/are correct?
Explanation
The Jet Stream is a geostrophic wind that generally blows from west to east across the upper layers of the troposphere at an altitude of 20,000 to 50,000 feet. Air masses with different temperatures collide to form jet streams. Thus, the location of the Jet Stream’s formation is normally characterized by surface temperatures.
Statement 1 is incorrect: Jet streams exist in both the Northern and Southern Hemispheres. They typically form near the boundaries of major air masses and are driven by temperature differences and the Earth’s rotation. The Polar Jet Stream and Subtropical Jet Stream are present in both hemispheres.
Statement 2 is correct: Not all cyclones form an eye. The eye is a distinct feature of well-developed, intense tropical cyclones. In contrast, temperate cyclones do not have an eye because there is no central area where winds and rainfall are calm or inactive.
Statement 3 is incorrect: The eye of a tropical cyclone is the calm center with the lowest surface pressure and the warmest air above it. At about 12 km high, the air in the eye can be 10°C or more warmer than the surrounding air, while at the surface, it’s only 0-2°C warmer.
Exam tip:
For S1, The use of the word "only" makes this statement absolute. Since the Earth is symmetrically divided into the Northern and Southern Hemispheres, and both have similar atmospheric circulation patterns, jet streams should exist in both hemispheres. Hence S1 likely false. For S3, Beware of antonym as they are easy to manipulate, is it "less" or "more"?

Q485. Consider the following events in the history of India: 1. Rise of Pratiharas under King Bhoja 2. Establishment of Pallava power under Mahendravarman-I 3. Establishment of Chola power by Parantaka 4. Pala dynasty founded by Gopala What is the correct chronological order of the above events, starting from the earliest time?
Explanation
Correct chronology is as follows: 2-4-1-3 The Pallavas were a powerful dynasty that ruled a large part of southern India between the 6th and 9th centuries AD, with Kanchipuram (now in Tamil Nadu) as their capital. The Pallavas achieved their pinnacle with Mahendravarman I’s rule (c. 600-630), who reigned alongside Harsha and Pulakeshin II. The Pala Empire, which started in the Bengal region and ruled throughout the post-classical period (8th and 9th century AD), was an imperial power. The empire was officially established when Gopala was chosen to rule as Gauda’s emperor in 750 AD. Nagabhatta I founded the Gurjara Pratihara Dynasty (8th to 11th Century AD) in the Malwa region around the 8th century AD. Mihir Bhoja (836-885 AD) was the greatest ruler of the Pratihara dynasty. The Cholas rose to prominence in the 9th century and formed an empire that included most of South India; Tanjore/ Tanjavur served as their capital. The reign of the Chola king Parantaka, who succeeded his father Aditya I as king, lasted from 907-953 AD.
UPSC 2020Polity · Preamble
Q486. The Preamble to the Constitution of India, is:
Explanation
The Preamble to the Constitution of India is part of the Constitution but lacks independent legal force. It outlines guiding principles like justice, liberty, and equality. The Supreme Court in Kesavananda Bharati (1973) affirmed it as integral to understanding the Constitution’s philosophy, although it doesn’t confer enforceable rights. It serves as a guiding tool for interpreting the Constitution’s objectives.
Additional insight:
In 1976, Preamble was amended by the 42nd Constitutional Amendment Act to add "Socialist, Secular, and Integrity". In the Berubari Union Case (1960), the Supreme Court had earlier held that the Preamble is not a source of power or substantive rights and has no independent legal effect. It also held that Preamble is not an operative part of the Constitution and lacks legal force.

Statement 3 is incorrect: Bangladesh, not Nepal, has been In-dia’s largest trading partner in South Asia over the past five years. In the fiscal year 2022-23 India’s exports to Bangladesh were valued at US$ 13.84 billion which makes it one of India’s top export destinations.

UPSC 2020Indian Economy · Agriculture
Q490. Which of the following factors/policies were affecting the price of rice in India in the recent past? 1. Minimum Support Price 2. Government’s trading 3. Government’s stockpiling 4. Consumer subsidies Select the correct answer using the code given below.
Explanation
Factors/Policies affecting the Price of Rice in recent past are:
Minimum Support Price: MSP is a type of market intervention that the government uses to protect farmers against a sudden drop in farm prices. Rice is included in MSP and thus the government announces MSP for rice, ensuring farmers receive a minimum price for their produce. A high MSP leads to increased procurement costs and can push up market prices. Government Trading: The government imports or exports rice through agencies like the Food Corporation of India (FCI). Restrictions or encouragement in exports/imports can affect domestic rice prices. Government’s Stockpiling: The government maintains buffer stocks under the Public Distribution System (PDS) and food security programs. Large stockpiling can reduce market supply, influencing prices. Consumer Subsidies: The government provides subsidized rice through schemes like the National Food Security Act (NFSA) and PDS. While subsidies help consumers, they can distort market demand and affect pricing trends.
