The answer is A. The freedmen's bureau was created to help former slaves. They didn't help out the whites. They helped blacks only. As for B, if your curious as to what organization did that, it was called the Freedmen's School. :)
(This famous order was given by Colonel William Prescott at the Battle of Bunker Hill on June 17, 1775)
As the British army marched on Bunker Hill, the American militia lured them closer… and closer… and closer… by not doing a thing. It would be like playing dead while a giant black bear sniffed at you, and then stabbing it in the eye at the last second.
This maneuver took nerves of steel, nerves that trickled down from Colonel William Prescott to his men. It was Colonel Prescott who gave the order, "Don't fire until you see the whites of their eyes!"
Once they got close enough, the Americans fired, decimating the British troops.
Easier Explanation: William Prescott shouted: "Don't fire until you see the whites of their eyes" explaining to the men that they had limited ammunition, and they needed to make every shot count.
Some may close, others may prosper.
