This question already has an answer here:
So, I just read an article, and was confused by the sentence:
In the study we just described, we found evidence that people’s self-discerning reflections — musings on whether parts of their identity truly define who they are or merely reflect their cultural upbringing — are a critical ingredient in the relationship between living abroad and self-concept clarity."

I always thought that plural verb can't come with the articles 'a' and 'an', as they are incompatible (plural and singular). Well, there are some exceptions like, 'They are a bunch of students'. However, the 'a' in this case is describing one group; it's not a problem.
The quoted sentence is a grammatically correct sentence too, as I've checked on Grammarly. So, can anyone explain to me why is it correct?
