It turned out that the water from the Broad Street pump 8.had been infected(infect) by waste.Moreover,Snow was later able to show a link 9.between other cases of cholera and the different water companies in London.Through Snow’s tireless efforts,water companies began to sell clean water,and the threat of cholera around the world saw a substantial decrease.10.Fortunately(fortunate),we now know how to prevent cholera,thanks to the work of John Snow.
