Answer:
The issues of emancipation and military service were intertwined from the onset of the Civil War. News from Fort Sumter set off a rush by free black men to enlist in U.S. military units. They were turned away, however, because a Federal law dating from 1792 barred Negroes from bearing arms for the U.S. army (although they had served in the American Revolution and in the War of 1812). In Boston disappointed would-be volunteers met and passed a resolution requesting that the Government modify its laws to permit their enlistment.
The Lincoln administration wrestled with the idea of authorizing the recruitment of black troops, concerned that such a move would prompt the border states to secede. When Gen. John C. Frémont (photo citation: 111-B-3756) in Missouri and Gen. David Hunter (photo citation: 111-B-3580) in South Carolina issued proclamations that emancipated slaves in their military regions and permitted them to enlist, their superiors sternly revoked their orders. By mid-1862, however, the escalating number of former slaves (contrabands), the declining number of white volunteers, and the increasingly pressing personnel needs of the Union Army pushed the Government into reconsidering the ban.

Answer:
1. The highest temperature in microwave for reheating depends on the manufacturers, but a study shows that it can reach up to 191oC for reheating and up to 200oC for cooking [4]. Microwave-safe plastics are those being able to withstand without smelting.
2. Microwaving food in plastic can cause chemicals to leach to food. Migration is likely to be greater with fatty food such as cheese and meat.
3. The best types of plastic for kitchen are those don't contain phthalates (polyvinyle chloride) and bisphenol A (polycarbonate). By contrast, the worst contain one of the two.[1][2][3]
Explanation:
Phthalates and bisphenol A are endocrine disrupters, both are known as reproductive toxicants. So if you use plastic in microwave, choose the ones with microwave-safe label. It's because they must pass a strict safety test by FDA to come to the market.[1][2]
