Question

In 1554, a cholera outbreak occurred in London. Cholera is a disease that causes intense diarrhea and can be fatal. At the time, many people believed that diseases were caused by “bad air.” John Snow had another idea; he thought that cholera was caused by something in the environment where people lived. He went door to door and made a map showing households that had cholera. He found that most of the cases were near the Broad Street Water Pump. John Snow made a case that the water from the pump was making people sick and the pump was shut down.

REASONING: If water was the cause of the sickness, then …

a) people all over the city would have cholera

b) cholera would be cured with water

c) only people near the pump would have cholera

Answer 1

Definitely NOT B, A..ok, I get it. But it's C because an infected person wouldn't just stay home, he would go and meet people, touch thing...and that's normal, but cholera is spread by consuming water and food, not through air, touching etc.
