Answer:
B) He had to restore confidence and unite the nation
Step-by-step explanation:
In the late 60s, the US had gone through a few turning points that changed society and politics. Things like the assassination of Martin Luther King Jr. and Robert Kennedy sparked riots and protests around the nation. Many Americans were tired of the disruption caused by protests and violence and started to lose faith in government.
Richard Nixon was a republican nominee elected on a basis of promises he made to the general American public. These included promising to end the Vietnam war, promising to restore law and order, and appealing to the Americans who disagreed with protest movements and the counterculture. With that in mind, options A, C, and D are dismissed. He was pressured to restore the faith of Americans and unite the nation after riots and protests all over, so the answer is B.
