This question already has an answer here:

I was recently typing up a short story essay when my computer's spelling & grammar check informed me that the sentence "What kind of things are in there?" should be written as "What kind of things is in there?" I am not sure which one is grammatically correct to use. I am sure, due to subject-verb agreement that my original was correct, but I am not sure.
