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.

A) One environmental factor that is typically present and required for the spread of infectious disease on an epidemic or pandemic scale is human migration, as it helps spread diseases that may have been isolated in a particular area to many other areas. The author mentions this in the last paragraph, “When Europeans colonized the Americas, smallpox followed. When soldiers fought in the first global war, influenza hitched a ride, and found new opportunities in the unprecedented scale of the conflict.” This shows that when people moved from place to place, diseases were more easily spread. When you look at previous epidemics and pandemics, and even the pandemic currently going on, one thing is always present: the disease was originally isolated in a single area, and then was later spread through migration.
B) One specific example of a 20th-century health epidemic that encouraged technological advancement was the cholera outbreak in the Romanian Army in 1913. This encouraged technological advancement, as it was within the army during the Second Balkan War, and having an outbreak in the middle of that was very dangerous. As a result, vaccines were quickly produced, systems were put in place that would prevent the spread, the infected were isolated, as well as several other procedures. That is just one of many examples of technological advancements made to stop epidemics.
C) One specific example of why the optimism of Sir Frank Macfarlane Burnet and George Marshall may have been misplaced is because in the end, vaccines only HELP manage the danger to a person, but there’s not a 100% chance of it eradicating it. Also, vaccines can evolve into new strains, ones that vaccines and the human immune system are not prepared for, so simply saying that infectious diseases are something of the past is ignoring that fact. Infectious diseases can come out of seemingly nowhere, so just because the current pandemic is taken care of, that does not mean that it is gone for good.
