With the help of the map he made, he got a    9     (value) clue about the cause of the disease and was able to announce that the water was    10     (blame). “King Cholera” was finally defeated.

In another part of London, he found supporting evidence from two other deaths that were    1     (link ) to the Broad Street outbreak. A woman,    2     had moved away from Broad Street, liked the water from the pump so much    3     she had it    4     (deliver) to her house every day. Both she and her daughter died    5     cholera after drinking the water. With this extra evidence John Snow was able to announce with certainty that    6     (pollute) water carried the germs.

To prevent this from     7     (happen) again, Jonn Snow suggested that the source of all the water supplies     8     be examined. The water companies were instructed not    9     (expose) people to polluted water any more.    10     (final) “King Cholera” was defeated.
