Options (a), (b) and (d) are incorrect:
Indian handicrafts suffered during British rule due to the influx of cheap machine-made British goods, which displaced local handicrafts in domestic and international markets. The number of Indian-owned factories was very limited during the 19th century. Most of the industries, including textile mills, were controlled by the British. The urban population did not see a rapid increase during British rule. While some cities grew due to British administrative and military needs, the overall urbanization rate was low compared to European countries. Moreover, much of India’s population remained rural, engaged in agriculture.
Exam tip:
British rule harm India, not positively impacted it. Options A, B and D indicates positive outcomes while C the odd one out is negative impact, turning food crops into cash crops, making peasants vulnerable to market fluctuations and famine. Hence

Q77. Consider the following statements: 1. The Barren Island volcano is an active volcano located in Indian territory. 2. Barren Island lies about 140 km east of Great Nicobar. 3. The last time the Barren Island volcano erupted was in 1991 and it has remained inactive since then. Which of the statements given above is/are correct?
Explanation
Statement 1 is correct: Barren Island is India’s only active volcano and is located in the Andaman Sea, within the Andaman and Nicobar Islands. It belongs to the volcanic arc of the Sunda Trench and is part of the Andaman Subduction Zone which makes it seismically active.
Statement 2 is incorrect: Barren Island is located about 140 km northeast of Port Blair (the capital of the Andaman and Nicobar Islands), not Great Nicobar. Great Nicobar is located far south of the Andaman Islands, whereas Barren Island is in the northern Andaman Sea.
Statement 3 is incorrect: The Barren Island volcano has erupted multiple times after 1991. Significant eruptions were recorded in 1994-1995, 2005, 2009, and most recently in 2017-2018. Thus, it has not remained inactive since 1991.
Exam tip:
When S1 says its active volcano and S3 says its inactive since approx 27 years, that means both statements clearly contradicts. Its a active volcano is a well known fact as being the "only" active one in India, thus S3 is more likely false, giving
option A as correct.

Q78. With reference to India’s decision to levy an equalization tax of 6% on online advertisement services offered by non-resident entities, which of the following statements is/are correct? 1. It is introduced as a part of the Income Tax Act. 2. Non-resident entities that offer advertisement services in India can claim a tax credit in their home country under the "Double Taxation Avoidance Agreements". Select the correct answer using the code given below:
Explanation
In 2016, India introduced a 6% Equalization Levy targeting income from online advertisement services provided by non-resident entities to Indian businesses. This measure aimed to tax digital transactions and level the playing field between domestic and foreign service providers. In 2020 it was expanded to include a 2% levy on e-commerce transactions by non-resident operators.
Statement 1 is incorrect: The Equalization Levy was introduced through the Finance Act, 2016 as a separate chapter and is not part of the Income Tax Act. This distinction ensures that the levy operates independently of the existing income tax framework.
Statement 2 is incorrect: Non-resident entities cannot claim a tax credit for this levy in their home countries which can potentially lead to double taxation. It doesn’t fall within the scope of Double Taxation Avoidance Agreements (DTAAs). Its exclusion from the Income Tax Act raises challenges regarding international tax credits and potential double taxation for foreign entities.

Q79. Regarding Wood’s Dispatch, which of the following statements are true? 1. Grants-in-Aid system was introduced. 2. Establishment of universities was recommended. 3. English as a medium of instruction at all levels of education was recommended. Select the correct answer using the code given below:
Explanation
Wood’s Dispatch (1854) is known as the Magna Carta of English Education in India. Under this government was to take up the responsibility for the Education of masses. It provided for hierarchy of Educational Institutions i.e. three tier education system. It also emphasised on Female, Vocational Education and teachers’ training. The Dispatch proposed secular education in Government Institutions.
Statement 1 is correct: The Despatch advocated for the introduction of a Grants-in-Aid system to encourage private and missionary enterprises in education. Under this scheme, financial assistance was provided to educational institutions that met certain standards thereby promoting the expansion and improvement of education.
Statement 2 is correct: It systematised the hierarchy from vernacular primary schools in villages at bottom, followed by Anglo-Vernacular High Schools and an affiliated college at the district level and affiliating universities in the presidency towns of Calcutta, Bombay and Madras.
Statement 3 is incorrect: The Woods Dispatch recommended English as the Medium of Instruction in higher studies and vernaculars language in at school level.
Exam tip:
S3 overreaches in its claim -- while English may have been promoted at the higher levels of education to train clerks and administrators, recommending it as the medium of instruction "at all levels" is logically flawed and pedagogically impractical. For primary and vernacular schooling, such a policy would have been both unfeasible and counterproductive, especially in rural colonial India. Hence likely false.

Q80. Which of the following led to the introduction of English Education in India? 1. Charter Act of 1813 2. General Committee of Public Instruction, 1823 3. Orientalist and Anglicist Controversy. Select the correct answer using the code given below:
Explanation
Statement 1 is correct: The idea of supporting educated Indians and promoting knowledge of contemporary sciences in the country was enshrined into the Charter Act of 1813. The Charter Act of 1813 permitted Christian missionaries to propagate English and preach their religion. It mandated the company to allocate one lakh rupees annually for the revival and improvement of literature and the promotion of science among the inhabitants of British India. The Act emphasized the need to educate Indians in Western sciences and literature which indirectly laid the foundation for English education.
Statement 2 is correct: A "General Committee of Public Instruction" was established by the Governor-General-in-Council in 1823 with the task of allocating one lakh rupees for educational purposes under the Presidentship of Lord Macaulay. Lord Macaulay’s Minute resolved the debate in favor of the Anglicists, directing the limited government resources toward the teaching of Western sciences and literature through the medium of the English language.
Statement 3 is correct: The Orientalist-Anglicist Controversy in the early 19th century centered on the medium and content of education in India. Orientalists led by scholars like H.T. Prinsep advocated for preserving traditional Indian knowledge through Sanskrit, Persian, and Arabic. Anglicists led by Thomas Babington Macaulay, pushed for English education to create a class of Indians who were culturally English but Indian by birth. The debate culminated in Macaulay’s Minute of 1835 which favored English education. Governor-General Lord William Bentinck endorsed this view thereby officially making English the medium of instruction in higher education.
