Cholera once was one of the most feared 1. diseases (disease) in the world. In the early 19th century, when 2. an outbreak of cholera hit Europe, millions of people died from the disease.

Snow subscribed 4. to the second theory. He began to investigate, 5. marking (mark) on a map the exact places where all those who died 6. had lived (live).
