But he became inspired when he thought about   62   (help) ordinary people exposed to cholera. This was the   63   (die) disease of its day.  64   its cause nor its cure was understood. So thousands of   65   (terrify) people died every time there was   66   outbreak. John Snow wanted to face the challenge and solve this problem. He knew that cholera would never be controlled until its cause   67   (find).

He was interested in two   68   (theory) that possibly explained how cholera killed people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease   69   their bodies with their meals. From the stomach the disease   70   (quick) attacked the body and soon the affected person died.
