Read the passage carefully and select the answer from the four alternatives:

I am a Robot. My registration number is CL-123X. My master Mr. Northrop, calls me ‘Cal’. The ‘X’ means I am a special robot for my master. He is a writer.

I am a simple Robot. I just pick up after him, run his printers, stack his discs and so on and so forth. He says, I do not talk back. I just do what I am told. That is good. Master is happy. I am happy.

I want to be a writer like my master. My master says, he writes mysteries. He tells about people who do wrong things, who hurt others. I feel very bad when I hear that. How can one think of hurting people?

My master says, ‘In my stories people who do wrong are punished’.

I think, that is bad too. It hurts people. My master has three different writers for writing stories. One is very old. He does not use it. I push its keys at night. Words are printed on paper. In the morning my master sees them and smiles. He says, ‘This is not a story, this is gibberish. But I’ll have you reprogrammed if you really want to be a writer’.

Which of the following word means ‘unintelligible talk’?
