UPSC 1999Indian Economy · External Sector of India
Q2863. Assertion (A): Information technology is fast becoming a very important field of activity in India. Reason (R): Software is one of the major exports of the coun-try and India has a very strong base in hardware.
Explanation
Assertion (A) is true: Information technology (IT) has become a key sector in India’s economy, contributing significantly to GDP, exports, and employment. The growth of IT services, software development, and business process outsourcing (BPO) has positioned India as a global leader in the industry. Government initiatives, a large English-speaking work-force, and cost advantages have further boosted IT expansion. Reason (R) is false: While software exports are indeed a major component of India’s IT sector, the country has not traditionally had a strong base in hardware manufacturing. Unlike software, which flourished due to outsourcing, India’s hardware sector has remained underdeveloped due to import dependency, lack of infrastructure, and high production costs. Only in recent years have initiatives like "Make in India" and the Production Linked Incentive (PLI) scheme sought to strengthen domestic hardware manufacturing.

Q2864. Assertion (A): Devaluation of a currency may promote export. Reason (R): Price of the country’s products in the international market may fall due to devaluation.
Explanation
Assertion (A) is true: Devaluation reduces the value of a country’s currency relative to foreign currencies, making its exports cheaper and more competitive in the global market. This can lead to an increase in the demand for exports. Reason (R) is true: As the local currency weakens against foreign currencies, goods from the devaluing country become cheaper for foreign buyers. This effectively reduces the inter-national price of these goods, resulting in increased demand for exports. For instance, after India’s 1991 devaluation, exports surged as Indian goods became more competitive globally. The Economic Survey (1991-92) confirmed that devaluation played a crucial role in boosting exports and improving India’s trade balance. Thus, Reason R correctly explains Assertion A.

Q2869. "India has the largest population of the Asian X. Today, there are just about 20,000 to 25,000 X in their natural habitat spreading across the evergreen forests, dry thorn forest, swamps and grasslands. Their prime habitats are the moist deciduous forests. The X population in India ranges from north-west India where they are found in the forest divisions of Dehradun, Bijnor and Nainital districts of UP to the Western Ghats in the states of Karnataka and Kerala and Tamil Nadu. In Central India, their population is distributed over Southern Bihar and Orissa. In the East, they are seen in North Bengal, Assam and a few other states. " The animal "X" referred to in this quotation is:
Explanation
The Indian elephant is the largest population of the Asian elephant species, and India is home to about 60-70% of the total population of Asian elephants. The passage refers to the distribution of the population in north-west India (Dehradun, Bijnor), western Ghats (Karnataka, Kerala, Tamil Nadu), central India (Southern Bihar, Orissa), and the eastern parts (Assam, North Bengal), all of which are areas where elephants are found in the wild. Elephants predominantly inhabit moist deciduous forests, dry thorn forests, and grasslands, which align with the habitats described. Distinctive Features:
They have smaller ears compared to their African counterparts. Their trunks are highly sensitive and versatile, used for feeding, drinking, bathing, and social interactions.

Q2870. The minimum land area recommended for forest cover to maintain proper ecological balance in India is:
Explanation
India’s National Forest Policy (1988) recommends that at least 33% of the total geographical area of the country should be under forest cover to maintain proper ecological balance. Forests play a crucial role in maintaining the environment by preventing soil erosion, conserving water, supporting biodiversity, and regulating the climate. Currently, India’s forest cover is around 24% of its total geographical area, according to the Forest Survey of India (FSI) report. While the target of 33% forest cover is still not fully achieved, ongoing afforestation and conservation programs aim to increase the forest cover to meet this goal.
