Question

which of these newspaper headlines would you be most likely to see during the height of mccarthys influence?
\senate hearings uncover alleged communist networks\
\supreme court limits government investigation into communist suspects\
\u.s. government formally apologizes to accused communists, offers compensation\
\international peace conference paves way for cold war resolution\

Explanation:

During the height of McCarthy's influence, there were widespread investigations into alleged communist activities. Senate hearings were a common part of McCarthy's tactics to root out supposed communist networks. The other options either go against the trend of McCarthyism (like the Supreme Court limiting investigations or the government apologizing) or are about Cold War resolution (which was not the focus during the peak of McCarthy's actions).

Answer:

"Senate Hearings Uncover Alleged Communist Networks"
