TORONTO—Even with a chilly mid-May breeze blowing off Lake Ontario, this city’s western waterfront approaches idyllic. The lake laps up against the boardwalk, people sit in colorful Adirondack chairs and footfalls of pedestrians compete with the cry of gulls. But walk east, and the scene quickly changes. Cut off from gleaming downtown Toronto by the Gardiner Expressway, the city trails off into a dusty landscape of rock-strewn parking lots and heaps of construction materials. Toronto’s eastern waterfront is bleak enough that Guillermo del Toro’s gothic film The Shape of Water used it as a plausible stand-in for Baltimore circa 1962. Says Adam Vaughan, a former journalist who represents this district in Canada’s Parliament, “It’s this weird industrial land that’s just been sitting there—acres and acres of it. And no one’s really known what to do with it.”

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
