Question 2

In a period of high inflation, the Reserve Bank of India (RBI) aims to stabilize prices by reducing the money supply in the economy. Which of the following actions would be most effective for the RBI to achieve this objective?

Accepted Answer

C. Increasing the Cash Reserve Ratio (CRR) for commercial banks. — Increasing the CRR mandates commercial banks to hold a larger fraction of their deposits with the RBI, thereby reducing the funds available for lending and contracting the money supply, which helps to curb inflation. Lowering the Repo Rate or purchasing government securities would inject liquidity, while decreasing SLR would free up funds for banks, all of which would exacerbate inflation.

Answer

A. Lowering the Repo Rate to stimulate credit growth.

Answer

B. Conducting Open Market Operations to purchase government securities.

Answer

D. Decreasing the Statutory Liquidity Ratio (SLR) requirements for banks.

Question 3

Steroid hormones, such as cortisol and estrogen, typically exert their effects by binding to which type of receptor?

Accepted Answer

B. Intracellular receptors — Steroid hormones are lipid-soluble and can readily cross cell membranes. They bind to specific intracellular receptors in the cytoplasm or nucleus, which then act as transcription factors to regulate gene expression. Other receptor types are typically for water-soluble hormones or neurotransmitters.

Answer

A. G-protein coupled receptors (GPCRs)

Answer

C. Ligand-gated ion channels

Answer

D. Receptor tyrosine kinases

Question 5

Kerala's west-flowing rivers are crucial for the state's ecology and economy. However, their characteristics make them particularly vulnerable to certain environmental challenges. Which of the following is the most significant environmental challenge faced by these rivers due to their inherent nature?

Accepted Answer

B. High susceptibility to pollution from industrial and urban waste coupled with low dilution capacity during lean seasons. — Kerala's west-flowing rivers are relatively short, have steep gradients, and are predominantly monsoon-fed, leading to significant fluctuations in water volume. During the lean seasons, their reduced flow significantly lowers their dilution capacity, making them highly susceptible to pollution from the dense urban and industrial settlements along their banks. While hydroelectric potential exists due to steep gradients and salinization occurs in lower reaches, pollution due to low dilution is the most pervasive and significant challenge.

Answer

A. Limited potential for hydroelectric power generation due to their short length and steep gradient.

Answer

C. Excessive siltation and delta formation at their mouths, causing navigation difficulties for large vessels.

Answer

D. Rapid salinization of their upper reaches due to tidal ingress from the Arabian Sea throughout the year.
