Answer:
rhyme ending
Explanation:
It is technically called end rhyme but I think they are supposed to be the same thing.
I think it is to take care of him
A. Wasn't.. This is because if you seperatevthe contractioninto two words it is was not, this would make the sentence be "Wally was not capable of lifting the heavy box."
If you were to do the same thing with weren't it would sound like "wally were not capable of lifting the heavy box." This does not make sense because "wally" is singular (so is "was not") and "were not" is pleural.
Hope this helps
If you want something I suggest about manatees?
