Answer:
It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions.
Step-by-step explanation:
John Walker was a druggist, who in 1827 invented a friction match. He experimented by tipping a mixture of sulphur, chlorate of potash, and sulphid of antimony, and frictioned it against a sandpaper that ignited a fire.
After several years of experimenting, Walker subsituted chemicals with phosphorus. The phosphorus match is considered to be the match because before the chemical friction was hard rubbing and sputtered and would ablaze in all directions.
Thus the statement that describes the problem that how phosphorus match solved is in the last statment. Therefore, the correct answer is option D.
