I have a similar question. This is how I rendered the logic going through the lesson.

1) Every great professional golfer has won a major. Rickie Fowler has not won a major. Thus, Rickie Fowler is not a great professional golfer.

2) Every key card holder can enter the hotel. To receive a key card, you must either be a member of the hotel club or have an active reservation at the hotel. Timothy has a key card, yet is not a member of the hotel club. Thus, he must have an active reservation at the hotel.

3) John saw his wife entering her ex-boyfriend's house one evening. When she returned home, her hair was disheveled and she arrived much later than she said she would initially. John broke up with because she had sex with her ex-boyfriend.
