Student: Test for natural language inference.
Premise: "A worker is driving a piece of green colored machinery on a city sidewalk."
Hypothesis: "A man is driving an orange tractor through a field."
Is the hypothesis entailed by the premise?
Options:
- yes
- no
- it is not possible to tell.
Teacher: Let's think:
A worker could mean a man or woman. The machinery doesn't necessarily have to be a tractor and it can only be either green or orange. The machinery cannot be driven on a city sidewalk and field simultaneously. So the final answer is no.
