2) (E) Some employees who use a Mac and have attended a security training seminar use a tablet. We know from the stimulus that some Mac users also use a tablet, and all tablet users have attended a security training seminar. Therefore, it must be true that some Mac users who have attended a security training seminar use a tablet.

3) (B) Some local bands are jazz bands. We know from the stimulus that all jazz bands are local. Therefore, it must be true that there are local bands that are jazz bands.
