Question

collect the quotation from the story that most strongly suggests that there is if one way of doing something keeps failing, try another way.
he threw away the hook without a second thought.
when philip got home that afternoon, he saw that the birdhouse was still hanging.
the birdhouse was finally a home.

Explanation:

The theme "If one way of doing something keeps failing, try another way" is supported by the idea that Philip initially used a hook (which presumably failed to work for the birdhouse), then abandoned that method, and the birdhouse was successfully hung. The statement that the birdhouse was finally a home shows that switching approaches led to success, matching the theme. The other options either show giving up on a method without a second thought or just observing the result without indicating a switched approach.

Answer:

The birdhouse was finally a home.
