1- The correct answer is D. One long-term effect of the Salt March was that the international attention forced Britain to grant Indians some rights.
The Salt March was a demonstration led by Mahatma Gandhi carried out between March 12 and April 6, 1930. This march became one of the most important events that led to the independence of India from the British Empire.
After a 300km walk, Ghandi arrived to the Indian Ocean coast on April 6, 1930. He advanced into the water and picked up some salt in his hands. By this highly symbolic gesture, Gandhi encouraged his compatriots to violate the monopoly of the state over the salt distribution. This monopoly forced all Indian consumers, including the poorest, to pay a tax on salt and forbade them to collect it themselves. On the beach, the crowd, nourished by several thousand supporters, imitated the Mahatma and collected salt water in containers. His example was followed by the whole country. From Karachi to Bombay the Indians evaporated the water and collected the salt in broad daylight in defiance of the British. The latter filled their jails with 60,000 Indian salt thieves. The Salt March is for the Hindus the equivalent of the Boston Tea Party, that led the United States to independence.
2- The correct answer is D. A long-term effect of the Long March was that Mao won support because he treated peasants fairly.
The Long March was the journey through the interior of China that was followed by the Chinese Red Army troops, the armed forces of the Communist Party of China, between 1934 and 1935, fleeing from the Republic of China's army. It meant the rise to power of Mao Zedong.
