She has a very ethical answer to my question.
When Travis sees Arlis playing in the drinking water (C) He feels happy because it reminds him of good memories of Old Yeller.
This scene shows us that Travis has matured and has a new perspective on life. He is not as stringent as he was before and takes time to enjoy the little things in life.
The correct answer is C. eliminate redundancies.
A wordy sentence contains a lot of words and is very long. If you want to shorten that sentence, you will have to read it carefully and look for words that are repeated, or have similar/same meanings, or are just unnecessary because they don't contribute to the sentence. When you eliminate those redundancies, you will fix your lengthy sentences.
