g When Rebecca and Julie worked together on a project last year, both did more than their share and earned a nice bonus from their boss. Julie was then sent to another state to help set up a new office over the summer, and from her messages on social media, Rebecca could tell that she was working harder than ever. In the fall, when Julie returned to her home office, Rebecca suggested that they work together on a new project. This time, however, things did not go well: Julie seemed to lose interest quickly, and Rebecca began to feel resentful when she realized that she was doing most of the work. What most likely happened

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
