Denny asked: Premise: "A middle-aged man relaxing on a couch reading a book."
Hypothesis: "A young girl is sitted at a desk staring straight into the computer while typing on the keyboard."
Do we know that the hypothesis entailed by the premise?.
Le: OK, so how can I answer with some explanation?
Middle-aged is not young. A girl is not a man. On a couch is not at a desk. One cannot be staring into computer while reading a book.
The answer: no.
