Read the excerpt from "Flowers for Algernon." I asked Dr. Strauss how Nemur could refute Rahajamati’s attack on his method and results if Nemur couldn’t even read them in the first place. That strange look on Dr. Strauss's face can mean only one of two things. Either he doesn't want to tell Nemur what they're saying in India, or else – and this worries me – Dr. Strauss doesn't know either. I must be careful to speak and write clearly and simply so that people won't laugh.

What does the final line of this excerpt foreshadow?
