Answer:
Option D
Step-by-step explanation:
I silently counted on my fingers: twenty-eight days until the end of September, then on into October until the first frost. Frost always killed fever. Mr. Carris said it drained the poison from the air. This referenced the idea that the frost would kill the epidemic.
Most doctors had predicted the fever would end when the cold weather returned.Almost all epidemics followed the same pattern,... disappearing with the first hard frost.
Daniel Defoe, in recording the end of the Black Death that visited London in 1665, wrote that "the winter weather came ,most of those that had fallen sick recovered, and the health of the city began to return."
