This is a part of modern racism.

Explanation:

Modern racism is a subtle form of racism, expressed in a more indirect way. It is still based primarily on prejudice but the individual carrying it out tends to be more indirect about it, such as avoiding going to places where he/she knows certain races will be, for example.

Explanation: Attributing bigoted opinions to sources other than prejudice and/or expressing biased attitudes in some "safe" areas but not publicly is a part of modern racism. Modern racism which rears its head at opportune moments and is defined as a form of prejudice in which racist views and stereotypes are neither expressed nor endorsed—it is a form of racism that is more oblique than confrontational, and often leads to a conflict in our own personal values. While it believes in the greater integration between people, however, it also believes that racial equality has been achieved and that there is no usefulness of further policies that promote equality. Simply put, if racism has been stamped out, then it is reasonable to maintain things the way they are.

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
