Explanation:

Part A's question is all about the purpose of President Obama's speech regarding the "Trayvon Martin Case." He was a 17-year-old African-American who was shot by Zimmerman, a man of mixed-race. His death stirred the public's interest and so Obama needed to make a remark on the situation.

Choice C best supports the answer to Part A because it talks about how Obama tries to reconcile the people's thoughts regarding the ruling of the case. He wanted people to know and recognize why the African-American behave in such a way and why they are prone to such situations. History plays an important role in such event. He wanted people to know about the division that is still existing in the society, especially among the African-Americans.
