My nephew , Matthew called today . He was at his grandma 's house and wanted to know if any of his cousins wanted to come swim in the pool with him . Jake was the only one not otherwise occupied , and since it was a sunny and hot day today , was more than happy to go cool off with Matthew .
Why did Matthew call his cousins to go to the pool ?

- None of the above choices .
 - Matthew 's grandmother wanted Matthew to have a friend to play with
 - Matthew wanted something else to do besides knit with his grandmother
