Denny asked: Premise: "A guitarist leads a congregation in worship."
Hypothesis: "A man teaches a congregation the new worship song he wrote."
Do we know that the hypothesis entailed by the premise?.
Le: OK, so how can I answer with some explanation?
A guitarist is not assumed to be a man. Leads does not imply that the guitarist is teaching. Leading a congregation in worship does not imply that he is teaching a new worship song he wrote.
The answer: it is not possible to tell.
