C. a greater number of high-level management positions
D. the creation of new job opportunities

D.

Explanation:

The creation of new job opportunities brought about the most changes for minorities and women. This is because when men went to war, women were needed to work in factories where men usually worked. Those women were able to manufacture weapons and machinery. In World War II, women even helped engineer the atomic bomb in New Mexico. Although women were not needed to work anymore once the wars were over- it still helped them on their journey for equal rights.

the emancipation proclamation was the aim of the war change to include the freeing of slaves in addition to preserving the union. the 13th amendment, which abolished slavery in the u.s. was passed on december 6th 1865.

as promised, lincoln waited to unveil the proclamation until he could do so with success from the union military advance. on september 22nd 1862, after a victory at antietam, he publicly announced a preliminary emancipation proclamation, declaring all slaves free in the rebellious states as of january 1st 1863.
