The species faces threats from habitat loss, hunting, and human encroachment, leading to its vulnerable status.

Q87. Which of the following statements correctly explain the impact of the Industrial Revolution on India during the first half of the nineteenth century?
Explanation
The Industrial Revolution in Britain led to the mass production of textiles and other goods in Britain, which flooded the Indian market. This caused a decline in demand for Indian handicrafts which could not compete with the cheaper, machine-made British goods. This led to the ruin of traditional handicraft industries and artisans. Machine-based production in Indian textiles became more prominent after the 1850s, with the establishment of British-owned factories like the Bombay Spinning and Weaving Mill (1854). The first railway line in India was opened in 1853 between Bombay and Thane. By the latter half of the 19th century, the railway network expanded rapidly to facilitate the movement of goods (especially raw materials for British industries). British goods were often imported into India without heavy duties. British colonial policy was designed to ensure that India served as a market for British manufactured goods.
Exam tip:
For (b), Why would colonizers industrialize India, when they wanted it as a raw material source + market? Industrialization would make India self-reliant against British interest. For (c), Railways in India began around 1853, this is second half of 19th century, is well known fact. For (d), Britain wouldn’t tax its own exports to India. In fact, they likely removed Indian tariffs to promote free entry of British goods. Hence all b, c and d are Likely false

Option 2 is incorrect: Papikonda National Park is located in the East Godavari and West Godavari districts of Andhra Pradesh. It lies in the Godavari River Basin, not the Cauvery Basin.
Option 3 is correct: Sathyamangalam Tiger Reserve (STR) is located at the confluence region of Western and Eastern Ghats, in the Erode district of the state of Tamil Nadu. In the northern part of Erode district, the Palar river flows and drains into the Cauvery river. The Bhavani River, a major tributary of the Cauvery, flows through this region.
Option 4 is correct: Kabini river, a tributary of the Cauvery river flows through the Wayanad Wildlife Sanctuary.

UPSC 2020Indian Economy · Public Finance
Q89. In the context of the Indian economy, non-financial debt includes which of the following? 1. Housing loans owed by households 2. Amounts outstanding on credit cards 3. Treasury bills Select the correct answer using the code given below:
Explanation
Non-financial debt refers to the debt owed by entities that are not part of the financial sector, such as households, businesses, and government bodies. This type of debt includes various forms of borrowing, such as housing loans, credit card balances, and government-issued instruments like Treasury bills. Housing Loans: Housing loans taken by house-holds are considered non-financial debt because they involve borrowing money for the purchase of property, which is a physical asset. These loans are typically not tied to financial assets like stocks or bonds. Credit Card Debt: The amounts owed on credit cards are also considered non-financial debt. Credit card debt is a form of borrowing, but it is not related to financial assets, rather to consumption or goods and services. Treasury Bills: Treasury bills are short-term borrowing instruments issued by the government to generate funds. Since they are issued by the government, which is outside the financial sector, they also fall under the category of non-financial debt.

Q90. Wellesley established the Fort William College at Calcutta because:
Explanation
Fort William College was established in 1800 by Lord Wellesley, the Governor-General of India in Calcutta (now Kolkata). The primary purpose of the college was to train British civil servants in Indian languages, customs, and laws to improve the efficiency of the East India Company’s administration in India. Lord Wellesley recognized that British officials often lacked knowledge of Indian languages, culture, and traditions which hindered effective governance. The college was designed to train newly recruited British civilians in Indian languages (such as Persian, Sanskrit, Arabic, and regional languages) and familiarize them with local customs and laws. He believed that a well-trained administrative cadre would help the East India Company govern India more effectively and reduce reliance on Indian intermediaries.
