Question

1. Tube wells are expensive.
2. They need power to operate.

Options

• (B) contradicts (A).

• (B) is the reason for (A).

• (A) is true but (B) is false.

• (A) and (B) are independent of each other.

Answer 1

(B) is the reason for (A).

Explanation:

Statement (B) provides the direct practical reason why tube wells are costly to install and maintain. Tube wells are bored far deeper into the ground than ordinary shallow open wells, where water can be pulled manually or with animals. Lifting water from these deep subterranean aquifers requires constant mechanical power, forcing farmers to invest extensively in electric, diesel, or solar-powered pumps, as well as ongoing electricity or fuel bills.
