Consider the following events and arrange them in correct chronological order:

1. Poona Pact
2. End of Civil Disobedience Movement
3. Gandhi-Irwin Pact
4. Second Round Table Conference

Explanation

The Gandhi-Irwin Pact was signed in 1931 to suspend the Civil Disobedience Movement and release political prisoners.

The Second Round Table Conference was held in 1931 after the Gandhi-Irwin Pact, with Mahatma Gandhi representing the Congress.

The Poona Pact was signed in 1932 between Mahatma Gandhi and B. R. Ambedkar to settle the reservation of seats for Depressed Classes in provincial legislatures.

The Civil Disobedience Movement officially ended in 1934 following partial fulfillment of Congress demands and continued negotiations.

Hence, the chronological order is: Gandhi-Irwin Pact → Second Round Table Conference → End of Civil Disobedience Movement → Poona Pact.
