I wanted to see if anyone can confirm the following sentence reads correct, with proper agreement:
"Now remember, your sales and marketing teams are the life force that keeps business flowing to you."
I believe this is correct because the nearest noun to the verb "keeps" is singular, but I wanted to make sure. I also believe it is okay to say "sales and marketing teams are the life force," turning these two groups into a singular noun, but again, I wanted to be absolutely sure. Combining singular and plural always seems a little uncertain to me. Thank you all in advance!
