Question

the united states was part of the conflict in bosnia during clintons presidency. as a result of international involvement,
bosnias ethnic relations grew worse.
serbia signed a peace agreement.
serbia refused to accept terms of peace.
bosnias muslim population returned.

Explanation:

During Clinton's presidency, the U.S. was involved in the Bosnian conflict. The Dayton Agreement was brokered, which led to Serbia (along with Bosnia and Croatia) signing a peace agreement. This ended the conflict. The other options are incorrect: ethnic relations did not grow worse as a result of international involvement (the aim was to improve them), Serbia did not refuse peace terms (they signed the agreement), and the return of Bosnia's Muslim population was more a result of post - peace settlement repatriation efforts rather than a direct immediate result of international involvement in the conflict - ending phase.

Answer:

Serbia signed a peace agreement.
