Slaves were traded, like other goods, throughout the region under muslim society.

The statement is true. In the Muslim societies, or rather Caliphates and empires, the slaves were traded just like the other goods. The slaves varied in ethnicity, race, culture, religion. The Muslim kept and sold as slaves the people that were captured in war. The ones that refused to accept their religion were also often enslaved and sold as slaves throughout their territory. There were slaves from Western Asian origin, from European origin, African origin, and they were all treated as not worthy of leaving, and that the only thing that they were partially good at was to serve and work for the Muslims.

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
