Hi Gitanjali —
Welcome to the forums — nice to have you here and I hope you are finding the Trainer useful —
The issue with that drill q is a shift in subject matter. The premises are about people in a club, and the conclusion is about members of the leadership committee. Without more information, we can’t conclude something about the leadership committee because we don’t know how the club and the leadership committee relate to one another.
Hope that helps clear things up and let me know if you have any follow-up — have a great wknd — Mike
