Answer:
A) One environmental factor that’s alluded by the author was the movement and migration of different cultures. When one group of people is immune to a certain disease that doesn’t mean all are. As stated in the text “Europeans colonized the Americas, smallpox followed. . . When soldiers fought in the first global war, influenxa hitched a ride”. Different exposure as a whole when it comes to people can make certain people immune to things that others are not, this is usually the cause for many outbreaks of sickness.
B) One specific example of a technological advancement during these pandemics were vaccines. The first vaccine being the flu vaccine after influenza spread, once people found out how to make vaccines other dieseases were easier to handle, polio, smallpox and other sicknesses went from unmanageable to under control once people started to take these vaccines.
C) One reason why Sir Frank Macfarlane Burnet and George Marshall have Mose likely been misplaced is becuase of the statement referenced in the text, “To write about infectious diseases is almost to write of something that has passed into history”. I say this because as we all know, diseases that we have vaccines for are still not 100% preventable. While yes, the vaccines do help manage and greatly decreases the amount of people that suffer from said disease, that doesn’t mean they’re gone. Which makes calling it something that has passed a rather bold claim because while yes the human immune system evolves to fight off certain diseases, there’s no saying that the diseases won’t evolve as well.
