Battle back<br>Sally had been sick for many weeks. She was feeling better. Her and a friend decided to go for a walk. It was great for Sally to get some fresh air. She felt much better after getting out of the house.
Sally felt better after going for a walk because getting fresh air cures you if you're sick.
The original statement was pretty clear that Sally felt better before going for a walk, and that the fresh air made her feel better because she was tired of being cooped up. Even if you think that fresh air does cure sickness, the sentence is incorrect. I think the system did not distinguish well between the two separate instances of feeling better in the original statement.
