Answer to Question 1

ANS: A
John Snow demonstrated that cholera was transmissible through contaminated water. He removed the pump handle from the contaminated water so an alternate source of water had to be used. Alexander Fleming created the first antibiotic. Legislators were responsible for encouraging the new process of vaccination and passing laws related to home quarantine.

Answer to Question 2

ANS: B
The media report news; they do not create it without any basis. Researchers are not asked to confirm a preconceived conclusion but to seek what factors are active in a situation. Group think is a well-known phenomenon, but one would have to ask what led the communication leaders to believe originally that there was a hazard in the environment. Risk assessment in a questionable situation begins with identifying a possible hazard and describing the risk.
