NDA (II) 2025 General Ability Test · Question 3 of 147

Correct — D, World War II. The question asks which item the passage does NOT connect with ecological degradation. Population growth, the excessive use of chemicals and desertification are all standard drivers or forms of environmental degradation, whereas World War II is a historical military conflict, not a factor tied to ecological degradation — so it is the odd one out.

• (a)Global population growth — Population growth increases pressure on land and resources and is a recognised driver of ecological degradation, so it is true and cannot be the 'NOT true' answer.
• (b)Excess use of chemicals — Over-use of fertilisers and pesticides is a well-known cause of ecological degradation, so this statement is true.
• (c)Desertification — Desertification — land turning to desert — is itself a form of ecological degradation, so this statement is true.

A 'which is NOT true / odd-one-out' comprehension item — three options are causes or forms of ecological degradation; World War II is not.
