An athlete wonders whether she has what it takes to win
The answer is "Detached."
To be detached literally means to be separated or isolated from something. So this word can help to indicate the dead-end and dull aspect of the street.
You didn't underline anything, so we cannot know for sure what the correct answer is. However, I'll just write down the entire infinitive phrases in these sentences, and you can see the answer based on that:
1. to see a great play
2. to cheer good plays
3. to practice until you know all the plays
