Question

Quizplus · Accepted Answer

A subject must agree with its verb in number. The subject in this sentence is a compound subject (you and your sisters).
When a compound subject consists of two words connected by "or", "either/or", "neither/nor", or "not only/but also", you need to use a verb that agrees with the subject that is closest to the verb.
The closest word to the verb (sisters) is singular so we need a singular verb (are going to).
Either you or your sisters are going to tell me who broke the window.
