What is one of journalist carroll kilpatrick's purposes for writing the article "nixon resigns"? to explain how the white house staff is preparing for a new president to indicate how the white house staff is unaffected by the change in presidents to convey how the white house staff is changing in the wake of nixon's resignation to share how the white house staff feels about nixon's resignation

The correct answer is the last one. Kilpatrick's article shares how White House staff feels about Nixon's resignation.

In the article, numerous aides and officials are quoted. Each gives his thoughts and/or opinions on Nixon's resignation. Many are sorry to see him go. Therefore the second option -- that the staff is unaffected -- is not correct.

The article does not say much about who will become president after Nixon. Furthermore, the staff itself is not changing; only Nixon is leaving. Therefore, the final answer is the correct one.
