2. Sudan War between the country's regular and paramilitary forces
3. Turkey Rescinded its membership of NATO

Show answer

Answer: (B) Only two pairs

Correct Answer: (b) Only two pairs are correct (Pairs 1 and 2).

Pair 1 — Argentina + worst economic crisis: ✓ CORRECT.

Argentina has been suffering severe inflation and economic turmoil.

Pair 2 — Sudan + war between regular army and paramilitary: ✓ CORRECT.

Fighting between the Sudanese Army (Gen. al-Burhan) and the Rapid Support Forces (RSF, led by Dagalo) has caused one of the worst humanitarian crises.

Pair 3 — Turkey + left NATO: ✗ WRONG.

Turkey has NOT left NATO.

While Turkey has been a difficult member and has clashed with other NATO countries, it remains a member.

There's no mechanism within NATO to expel a member.

Quick elimination: If you know Turkey is still in NATO (which is basic current affairs), you can immediately eliminate options that include Pair 3.

Why this was asked

Argentina's inflation reached over 200% in 2023-2024, making it one of the world's worst economic crises currently.

Sudan's civil war between the army and RSF paramilitary started in April 2023, creating a major humanitarian crisis that dominated international news in 2023-24.

Turkey remains a NATO member despite tensions - there is no mechanism in NATO's charter to expel a member country.
