Student asked: Test for natural language inference.
Premise: "A man and boy are eating food outdoors while sitting down next to a shopping cart."
Hypothesis: "A father and son catch a bite to eat before heading home."
Is the hypothesis entailed by the premise?
Options:
- yes
- no
- it is not possible to tell
