Europeans ignored cultural divisions when settling colonial boundaries because

Europeans had no interest in or concern for African cultural divisions.

Explanation:

With the possible exception of the Americas, there is no other continent ton which European influence has been so profound. In the city of Berlin in 1885, major European powers carved up a blank map of Africa by the strokes of a pen. They created more than 40 entirely new countries overnight without regard to existing political entities, ethnic boundaries, historical relationships, alliances, and geographic and demographic variables. Africans had to live within the new boundaries in completely alien political systems with contrived citizenry.

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
