Student asked: If "There is a shopping cart and a person laying on the ground in a green field of grass." does that mean that "There is a shopping cart and a person laying down."?
Options:

Teacher's response: Let's think. I don't think this is a valid sentence because when you're laying on the ground you are definitely laying down. The answer is it is not possible to tell.

Student asked: Given the sentence "There is a notre dame quarterback dropping back into the pocket at a game." is it true that "A football game is in progress."?
