I am writing some sentences to tell my friends that they should drink some red wine in dinners.
Drinking wine has a lot of positive sides that [depend / depends] on which type of wine people purchase, for example, some doctors have recommended people drink red wine because they are better for health.
I have stopped writing after this sentence, because I am not sure
whether I should use a singualr verb or not.
Here is the reason why I hesitate:
Drinking wine is singular, but a lot of positive sides is plural, so I am confused.
