Answer:
Algernon's new symptoms foreshadow:
C. Charlie will start to get worse also.
Explanation:
"Flowers for Algernon" is a story by author Daniel Keyes. The main character is Charlie, a man in his thirties whose IQ of 68 is tripled when he undergoes an experimental surgery. Before the surgery, Charlie gets to "meet" Algernon, a lab rat that has undergone the same surgery and whose IQ has also been increased. Charlie is fascinated by Algernon's intelligence, wishing to become as smart as the rat.
After Charlie's successful surgery, Algernon's intelligence begins to decline. The doctors involved int he experiment knew this was a possibility. As a matter of fact, they warned Charlie before the surgery, but he did not care. Now that he sees it happening to Algernon, Charlie realizes, as do the others, that it will most likely happen to him as well. As Algernon gets worse, Charlie suffers in anticipation for himself.
