3-1 Problem-Solving Strategy:
Eliminate Possibilities
Example
Gene is going to his friend Jan’s family reunion. He wants to learn
the names of Jan’s aunt, uncle, cousin, sister, and grandfather. Use
the following clues to help Jan match the names to the correctrelative.
Sue played racquetball Tuesday
Marla is an only child.
Jan’s sister does not like racquet sports.
John’s son is Jan’s father. Tom and Marla are married.
Explore You must match each relative with his or her name by
examining the given clues
