Anthropology is a science, but it's not a hard science like chemistry or physics. Unlike molecules or subatomic particles, human beings are far too variable to make good scientific subjects. Still, science is built around identifying patterns, and humans, while not always consistent, do behave in predictable ways which can be observed and, maybe, explained. Sociologists and psychologists construct surveys and experiments as instruments to study human behavior and identify patterns. In anthropology, we consider ourselves as the instruments of analysis. We may use some statistical models, but mostly we interpret what we see through the lens of our training and experience, looking for patterns in the form of culture. Do you think this is a valid means of understanding the world? Why or why not? What problems do you see emerging from this kind of work and how can we minimize them? What value does ethnography have?

dude you should crop your image so only the question shows. but   can you explain it better

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
