How did the events described in Source 2 influence world powers’ stance on foreign intervention in the late 1990s and early 2000s? A:The use of military force to prevent humanitarian crises increased.
B:The international community further limited peacekeepers' roles.
C:World powers contributed more troops to United Nations peacekeeping forces.
D:Less-developed countries could no longer rely on outside forces to protect innocent lives.

The correct answer is B) The international community further limited peacekeepers' roles.

Unfortunately, you forgot to attach "source 2." Without it, we do not know what is its content.

However, trying to help you we did some deep research and can comment on the following.

You are probably referring to the speech delivered by Rwandan professor Joseph Nsengimana, speaking to the United Nations on the anniversary of the Rwandan genocide, 2009.

The events he described influenced world powers’ stance on foreign intervention in the late 1990s and early 2000s in that B) The international community further limited peacekeepers' roles.

During his speech, professor Joseph Nsengimana said "In April 1994 about five thousand men, women, and children had sought refuge with the Belgian contingent of the United Nations peacekeeping force, based at the E.T.O (a technical school), near Nyanza-Kicukiro. Even though they were surrounded by their killers, the UN forces withdrew, leaving them to be slaughtered by Interahamwe militias and the then Rwandan Armed Forces. This site symbolizes the international community’s failure in Rwanda..."

This makes us remind that a major difference between the international responses to genocide in Bosnia and in Rwanda, is that ethnic cleansing in Bosnia led to a military response from international forces but ethnic cleansing in Rwanda did not.
