premise: A man with a plaid shirt and green hat mows the lawn near the sidewalk.
hypothesis: A man doing snow angels in the grass.
explanation_1: Mowing and doing snow angels cannot be done simultaneously.
explanation_2: The man cannot mow the lawn at the same time that he is doing snow angels.
explanation_3: If there is snow on the ground, one cannot mow the lawn.  Doing snow angels is a form of recreation and mowing the lawn is a chore.
