When Nixon refused to withdraw support of Israel, OPEC responded by:

O

A. refusing to sell oil to the United States.

Explanation:

Although OPEC had traded with US primarily for oil during that time the diplomatic pressure and the differences due to the support for Israel became too great for them

This resulted in the fact that they with drew from the trade deals with US and the nation was left to fend for itself for its massive oil needs.

It served as a catalyst for more open realizations for trade with neighbor nations and reliance on other sources.

The war had forced US to look for different trade partners.

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.
