The correct answer for 1 is C. a way to make large quantities of steel in a gas furnace. This enabled things to be made out of metal which led to huge ships and huge machinery that could produce even more and be even more durable. The correct answer for the second is B. Electric lamps. TV became a thing in the 50s, not in the industrial revolution. Electric typewriters and stereos came at around the same period.
