Final answer:
Gandhi's 'Quit India' speech differed from previous efforts of Indian nationalists as it demanded an immediate end to British rule.
Step-by-step explanation:
Gandhi's 'Quit India' speech differed from the previous efforts of Indian nationalists in that it demanded an immediate end to British rule.

This speech marked a turning point in the Indian independence movement, as Gandhi called for decisive action and a complete break from British colonial rule.
