This is excerpt from Manhattan Guides:
The first instance of the verb should usually match the helping verb in tense. If you need to change
tenses, repeat the whole verb in the new tense.
Wrong: I have never seen an aardvark, but last year my father DID.
Right: I have never seen an aardvark, but last year my father saw one
Can anyone help me explain what is it trying to convey?? I do understand by logic and usage of grammar that latter is the right answer but how does it support the text mentioned??
Any help would be appreciated!!
Thanks alot
