How did the compromise of 1877 affect the political participation of african americans? southern legislatures, which were given power in the compromise, failed to persecute the ku klux klan. the freedmen's bureau, which encouraged civic programs for freed slaves, was given more funding. the military, which had protected african american rights, was removed from the south. the president, who was a southern democrat, began to oversee a rollback of african american rights.

The military, which had protected African American rights, was removed from the South.

Explanation:

After the Compromise of 1877 the reconstruction era was formally ended, and that meant that the south had re-gain its democratic self-gobernability back, by doing this the military from the northern states was going to be removed and protection for the african american community was removed with it.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals

our brain need to reach a certain level of development   before it could interpret and understood sound with high difficulties. to proof this, we just need to pay attention in musical preference between children and adults. it is far less likely that children would enjoy things such as orchestra or rock band as much as adults due to the difference in this ability.
