According to "Introduction to Cultural Rebellion: Mid-Twentieth-Century Voices," which statement best reflects one difference between postwar science fiction writers and writers of the beat generation?

Postwar science fiction authors wrote to warn society of the potential results of its values, while beat generation authors wrote to reject society's values.

Explanation:

Postwar science fiction stories and books were questioning the thought and culture during the Cold War. Set in dystopia, the authors tried to make people think about the realities of possible threats and dangers of a society.

The beat generation of the postwar era had nothing to do with preservation or quest of the societal values. They were rather interested in vices such as sexual liberation, psychedelic drugs and spiritual quest therefore the authors were rejecting values.
