Explanation:

The Brown v. Board of Education of Topeka was a landmark litigation or court case between Oliver Brown and the Board of Education in which the justices of the Supreme Court unanimously ruled (9-0) in 1954 that racially segregating children in public schools was unconstitutional because it violates the Equal Protection Clause of the Fourteenth Amendment (14th) of the Constitution of the United States of America.

Meanwhile, on the 4th of September, 1957, the first day of resumption of class activities at Central High School, the Governor of Arkansas, Orval Eugene Faubus invited the Arkansas National Guard to block all African-Americans (black) students from entering into the school.

Hence, the states with segregated school systems responded to the Supreme Court ruling in Brown v. Board of Education by attempting to keep their schools segregated.

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
