Hmm -- I didn't see anything about South Vietnamese troops in that article. Did I miss something?

In any case, C is wrong. Read it again.

B is the right answer. Thank you guys!!

Yes, B.

To determine the reason why President Johnson significantly increased the number of U.S. troops in Vietnam in 1965, we can analyze the given options: A) air strikes had made it safe for ground forces to enter the war, B) communist forces continued to fight despite intense U.S. bombing, and C) South Vietnamese troops were no longer willing to fight.

Option A can be eliminated as a potential reason because it suggests that ground forces were only sent after air strikes had made it safe, which does not explain why there was a significant increase in troops.

Option B is a plausible reason because it suggests that despite intense U.S. bombing, communist forces continued to fight. If this were the case, the U.S. may have deemed it necessary to send more troops to counter the relentless resistance.

Option C does not provide a direct reason for increasing U.S. troops. While it is true that South Vietnamese troops' willingness to fight may have been a factor, it does not explain why President Johnson specifically decided to increase American troop presence.

Therefore, the most likely reason for President Johnson's significant increase in U.S. troops in Vietnam in 1965 is B) communist forces continued to fight despite intense U.S. bombing.
