Question

Neither the lion tamer nor the clowns _________ signing any autographs tonight. are is was None of the above

Answer 1

I believe that the best answer for this question is "are." You are referring to two parties here, both the lion tamer and the clowns. This would mean that your applicable verbs must also be plural. Since "are" is the plural version of "is," it is the most suitable word to use in this situation. Hope this helps.
