"Can he hear what I'm saying? I mean, can he understand me?"
"That's a hard question to answer. I should say that the understanding was of a very low level. Here, I'll show you what I mean." He turned and looked directly at the seated spaceman.
"Captain Gisser, how old are you?" he asked in a firm, clear voice.
There was no answer.
"Gisser, when were you born?"
Still no answer.
"Gisser, tell us when you were born."
"Twelve, Eight, Seven sixty-four," Gisser said promptly.
