Question already asked before :)
"“On the Mode of Communication of Cholera” was a scientific text written by Dr. John Snow in 1855 about the disease cholera. The two primary purposes of this text were to persuade officials and citizens to be more conscious about sanitation, and to inform readers about new ideas about the disease using scientific evidence as support. The answer would be letters A and B."
