Careful Reading 20 Snow began by marking on a map the exact places where all those who died had lived. There were multiple deaths near the water pump in Broad Street (especially house numbers 16, 37, 38, and 40). However, some households (such as 20 and 21 Broad Street, and 8 and 9 Cambridge Street) had had no deaths. These people worked in the pub at 7 Cambridge Street. They had been given free beer, and so had not drunk the water from the pump. Snow suspected that the water pump was to blame.What is more, in another part of London, a woman and her daughter had died of cholera after moving away from Broad Street.It seemed that the woman liked the water from the pump so much that she had it delivered to her house every day. As a result of this evidence, John Snow was able to announce that the pump water carried cholera germs. Accordingly, he had the handle of the pump removed so that it could not be used. Through this intervention, the disease was stopped in its tracks. think of a method collect data analyse the results find supporting evidence draw a conclusion find a solution Mission completed You got an advanced guided book. 1. 让学... text has been truncated due to evaluation version limitation. 21 Task 6.
