Question

select the quotation from the story that most strongly suggests that the theme is if you want to achieve something, you have to take risks. as she walked out of the auditorium, marjorie thought, whatever happens, im glad i did it. only one thing kept her from dropping out: she couldnt get a part in the musical if she didnt try out. after last period, she took a deep breath, walked down the hallway, and added her name to the list.

Explanation:

The third quote shows the character taking action (adding her name to the list) which is a risk - related behavior as she doesn't know the outcome. The first quote is about being glad after the action, and the second is about the motivation for not dropping out.

Answer:

After last period, she took a deep breath, walked down the hallway, and added her name to the list.
