Would you like to give me options? As soon as you do, I will edit my answer.
There is no adverb. There would be if it was slowly grooms or another word before grooms, the verb.
Past tense of see = saw
past tense of wake = woke
past tense of eat = ate
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
