Two questions

<p>Recently I've decided to take up the sore subject of the SAT again and have worked through the Barron Grammar workbook for SAT and ACT. However there are two sentences about which I have doubts. Both are written as shown in the answers.</p>

<p>On second thought, either Brian or you is going to be the male lead in the play.</p>

<p>On the previous page it states that "When a subject contains a pronoun that differs in person from a noun or another pronoun, the verb agrees with the closer subject word", going as far as to give the example of "Either he or I am planning to work on Saturday". Thus, shouldn't it be either Brian or you ARE going to be the male lead in the play.</p>

<p>Jim couldn't tell who is more stubborn-his sister or his brother.</p>

<p>I cannot explain why this sentence feels awkward, but it just seems to be better fit as Jim couldn't tell who WAS more stubborn.</p>

<p>Thanks.</p>
