- Y. We get this from combining first two statements.
- Y. We know there is at least one unhealthy dish on special, and all dishes on special come with the customer’s choice of fries or soda.
- N. We know stuff about specials on the chalkboard, but not about other things that might be on the chalkboard.
- Y. We know that all specials on the board, and some of these specials are unhealthy.
- N. See #3.
- N. Tempting, but we don’t have enough info to infer this. The board could have a majority of healthy dishes and still satisfy the given rules.
- N. We don’t have info that allows us to make this inference about healthy dishes.
- Y. We know most dishes are offered on special, and all that is offered on special goes on the board — this is enough to infer that most dishes go on the board.
- Y. Since we know that the specials constitute the majority of total dishes, and all specials are on the board, there is no way the number of non-specials on the board can be greater.
- N. We don’t know about the exact overlap between dishes that are unhealthy and those on special, and so we can’t guarantee this inference.
