Hand axes, cave paintings, fire, and spears are all inventions related to which cultural stage?

The stone age, or the paleolithic age.

Explanation:

The stone age (paleolithic) is a relatively self explanatory answer in the sense that, most hand axes and spears were made of hard stones shaped and sharpened into points and sharp edges. Cave paintings are from around the upper paleolithic ages. These inventions may dip into the earliest stages of the neolithic period as well (also known as the new stone age)

Good Luck!

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
