Question

the accusation against j. robert oppenheimer was an example of
a. the strength of the anti-nuclear weapons movement.
b. guilt by association during the red scare.
c. the necessity of bomb shelters in case of nuclear war.
d. the protection of civil liberties such as freedom of speech.

Explanation:

During the Red Scare (McCarthy era), J. Robert Oppenheimer faced security clearance revocation. The accusations relied heavily on his past associations with left-leaning individuals and groups, rather than direct evidence of wrongdoing, which is a classic case of guilt by association. The other options are incorrect: there was no major anti-nuclear movement at the time of his hearings, bomb shelters are unrelated to his case, and his hearings represented a restriction of civil liberties, not protection.

Answer:

B. guilt by association during the Red Scare.
