(Answer if you have read or watched the movie Fences)
How does Rose act as a foil for troy?

These characters, known as foil characters, are Gabriel, Lyons, and Bono. I believe the most important foil character in this play is Bono. Bono, from his very first introduction, seems to be a carbon copy of Troy. The act the same, speak the same, work the same job and enjoy the same past times.

Explanation:

Troy criticizes Rose's enjoyment of playing numbers, a game like the lottery that Lyons also enjoys. Troy displays his sense of responsibility in his reaction to Rose's hobby, but simultaneously provides evidence of his selfish treatment of Rose.
