Answer:
Failure can strengthen a person because it creates a harsh determination, it is a humbling experience, and it teaches a lesson.
Explanation:
alliteration
The line has the /w/ sound repeated three times. Alliteration is the repetition of the same sound within a group of words. A simile is a comparison using like or as. The line does not have either like or as. An echo is when the end of a line or stanza is repeated like an echo. This is not the case either. The line also does not have personification (the giving of human-like traits to a non-human thing).
