The right to vote in an election

Explanation:

African Americans didn't get the right to vote until 1965 when the Twenty-fourth Amendment was made. It was then that the related laws, voting rights have been legally considered an issue related to election systems. While on the other hand, the right of women to vote in elections begins in the mid-19th century.

District of Columbia residents have no representation in the Senate. The Twenty-third Amendment, adopted in 1961, entitles the District to the same number of electoral votes as that of the least populous state in the election of the President and Vice President.

Lastly, 18 years old rights to vote was considered after the Twenty-sixth amendment. This amendment was important to the Student Movement because they declared that if they were old enough to be drafted into a war they were against, then they should be old enough to vote against and have a voice in their government. It was proposed by Congress on March 23, 1971, and ratified on July 1, 1971, the quickest ratification of an amendment in history.

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.
