Which of the following conclusions can be drawn from the passage?
Mohandas Gandhi, also known as Mahatma Gandhi, developed a policy of passive resistance in his civil rights struggle for Indian immigrants in South Africa, and later in the campaign for Indian independence from British rule. The writings of the Russian author Leo Tolstoy and the essay, "Civil Disobedience, " by nineteenth-century American Henry David Thoreau inspired Gandhi. Gandhi called acts of nonviolent resistance by the term satyagraha, Sanskrit for "truth and firmness. " The Salt Satyagraha of 1930 exemplified his policy. In protest against the British government's salt tax, he led tens of thousands of Indians on a 200-mile march to the Arabian Sea, where they made salt from evaporated sea water. Thousands, including Gandhi, were arrested. When the British con-ceded to his demands, Gandhi stopped the campaign. He was released from prison in 1931, and that same year, he traveled to London as a representative of the Indian National Congress to negotiate reform measures.
Gandhi's nonviolent protests were effective political tools.
The British did not respond to the Salt Satyagraha.
Gandhi refused to support the British government in World War II until it granted India its independence.
India could not win its independence without resorting to violent revolution.
The British concession to Gandhi's demands shows that his use of nonviolent protest was an effective political tool. choice c is a detail from the passage; choices b and e are untrue; and choice d is not supported by the passage
