Statement I: Mahatma Gandhi went on a fast unto death against the Communal Award announced by the British Government.

Statement II: The Poona Pact resulted in a joint electorate with an enhanced number of seats reserved for Depressed Classes.

Statement I is true: In September 1932, Mahatma Gandhi went on a fast unto death to protest against the Communal Award, which granted separate electorates to the Depressed Classes. He feared this would permanently divide Hindu society.

Statement II is true: The protest led to the signing of the Poona Pact between B.R. Ambedkar and Gandhi's supporters. It abandoned separate electorates in favor of a joint electorate, and the number of reserved seats for the Depressed Classes was significantly increased (from 71 to 147 in provincial legislatures).

Conclusion: Both statements are factually correct. However, Statement II describes the outcome of the fast mentioned in Statement I, not its cause. Therefore, Statement II is NOT the correct explanation of Statement I.
