Question 3

The 'Green Revolution' in India primarily aimed to address which critical challenge of post-independence agriculture, and what was its unintended consequence?

Accepted Answer

A. To increase food grain production by introducing high-yielding varieties and modern farming techniques, but it led to increased regional disparities in agricultural development. — The Green Revolution successfully boosted food grain production using high-yielding varieties and modern techniques, but it exacerbated regional disparities as benefits were concentrated in Punjab, Haryana, and UP. Option B is incorrect because while irrigation did increase, water depletion is a separate issue linked to policies like free electricity for farmers. Option C is unrelated to the Green Revolution's primary focus. Option D misrepresents the goal, as mechanization was not the core strategy.

Question 8

A patient's arterial blood gas (ABG) results show a pH of 7.25 (normal 7.35-7.45) and a bicarbonate (HCO3-) level of 18 mEq/L (normal 22-28 mEq/L). This pattern is most consistent with:

Accepted Answer

C. Metabolic acidosis — A pH of 7.25 indicates acidosis (below the normal range). A bicarbonate (HCO3-) level of 18 mEq/L, which is also below the normal range, signifies that the primary cause of this acidosis is metabolic. This pattern is therefore consistent with metabolic acidosis, where there is an excess of acid or a loss of bicarbonate in the body fluids.
