Question

which men testified against nixon during the watergate hearings?
○ alexander butterfield and carl bernstein
○ bob woodward and john dean
○ john dean and alexander butterfield
○ john dean and archibald cox

Explanation:

Carl Bernstein and Bob Woodward were investigative reporters who broke the Watergate story, not witnesses at the hearings. Archibald Cox was the special prosecutor in the case, not a testifying witness. John Dean, Nixon's White House Counsel, testified about the cover-up, and Alexander Butterfield revealed the existence of Nixon's secret White House taping system during the hearings.

Answer:

John Dean and Alexander Butterfield
