Question

“After writing all night, Sandra finally had a good introduction, but –“

How do I finish it off? It's supposed to be a parallel structured ending... I don't get it.

Answer 1

Parallel structure: means using the same pattern of words to show that two or more ideas have the same level of importance in the sentence

so maybe ... " but the good introduction she had been writing all night did not meet her standards "

I'm not 100% sure on my parallel structured ending suggestion.lol
