answer the questions (finish exercise 2 on page 3)
1. john snow believed idea 2 was right. how did he finally prove it?
(john snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.)
2. do you think john snow would have solved this problem without the map?
(no. the map helped john snow organize his ideas. he was able to identify those households that had had many deaths and check their water-drinking habits. he identified those houses that had had no deaths and surveyed their drinking habits. the evidence clearly pointed to the polluted water being the cause.)
3. cholera is a 19th century disease. what disease do you think is similar to cholera today?
(two diseases, which are similar today, are sars and aids because they are both serious, have an unknown cause and need public health care to solve them.)
