input: Text: The Last Monster By GARDNER F. FOX Irgi was the last of his monster race, guardian of a dead planet, master of the secret of immortality.

  Question: How is communication between the Terrans and Irgi conducted?

   (B) Irgi restrains and sedates the crewmen, then hooks them up to an instrument that converts brain wave activity to images, and he is able to see what they are thinking. This is one-way only, from the Terrans to Irgi.
   (C) At first, Irgi realizes that he is transmitting at a frequency below the threshold of human hearing. After he raises the frequency above twelve per second, the crewmen are able to hear him, and he can hear them.
   (D) Irgi provides the crewmen with a brain wave recorder, and hooks it up to himself and lets the crew see the images. When they understand, they hook themselves up so that Irgi can also see the images of their thoughts.
  Answer:
