True or false: the following sentence has correct subject-verb agreement.

Question

People in central Italy enjoy eating many types of meat, but neither beef nor liver outshine the popularity of the region's top meat, pork.

Answer 1

The only error that I perceive is that it should say OUTSHINES because the subject is NEITHER (neither one) and thus it is a singular subject.

Answer 2

All correct except for "outshine" which references the singular "neither". It should have a final "s" (outshines) especially in formal usage. Consider that there are mixed opinions on use and some consider either "outshine" or "outshines" to be correct.
