Answer:
The correct answers are:
The literature focused on the realities of war.
It was written with a purpose to actually end the war.
Explanation: With the upset caused by the Vietnam War in the early '60s, more voices for change were heard. Major writers included such poets and thinkers as Denise Levertov, David Lance Goines, and Muriel Rukeyser. But they also included novelists who did not write against the war but who were still major literary lights, such as John Updike. Writers of the Vietnam War era tended to focus on the rage and sadness of war, violence, injustice, morality and evil, coming of age, the war itself.
