Student asked: Given the sentence "A group of climbers in silhouette stare towards the sun over the mountaintops." can we conclude that "A group of climbers have just reached the summit of a mountain just in time to see the sunset."?
Options:
- yes
- it is not possible to tell
- no

Student asked: Given the sentence "A woman carrying a bag over her shoulder holds hands with a person wearing loose jeans while walking along side a row of trees towards a red sign." can we conclude that "The woman and ther person holding hands were going to do laundry."?
Options:
- yes
- it is not possible to tell
- no
Teacher's response:
Let's think. People walking along side a row of trees towards a red sign aren't going to do laundry at that instant. It is unlikely that someone with a bag over her shoulder is going to do laundry. The answer is no.
