Question

What leads Mr. Cavor to believe that it may be possible to communicate with the Selenites? He observes that they have ears on the sides of their heads. He reasons that intelligent beings walk erect and have hands. He notices that the Selenites appear to be friendly. He remembers the hypothesis of Kepler.

Answer 1

He believes that they might be able to communicate with the Selenites because: He reasons that intelligent beings walk erect and have hands.

He says: “They are reasonable creatures—they can make things and do things. Those lights we saw. . .”

When he spoke again it was to confess, “After all, they are more human than we had a right to expect. I suppose—”

“I suppose, anyhow—on any planet where there is an intelligent animal—it will carry its brain case upward, and have hands, and walk erect.”

Answer 2

He reasons that intelligent beings walk erect and have hands.

Step-by-step explanation:

For Mr. Cavor, the Selenites have hands and can walk upright, so there is nothing to question their intelligence and their ability to develop correct and efficient communication. Anyway, Mr. Cavor believes that the Selenites are human beings enough to communicate and understand what he was talking about.

In short, Mr. Cavor believes he can communicate with the Selenites because he argues that intelligent beings walk upright and have hands.
