Can someone help me out with these grammar questions?

Test Preparation SAT Preparation
1

<li>Neither Bradley, nor more recent critics who have written on Shakespeare’s tragedies, has been able to give a convincing explanation for the timing of events in Othello. No error.</li>
</ol>

<p>While the answer is “has been”, don’t you have to maintain parallelism in a neither… nor comparison? I had thought “more recent critics” wasn’t parallel and chose it. </p>

<p>Another:</p>

<li>The president has designated Senator Frank as one of the Congressmen who are going to attend the conference on nuclear waste disposal.</li>
</ol>

<p>This one is supposedly “no error”. But I thought it was “are going”, since it doesn’t agree teh subject, “one of/Senator Frank”. This is from the Barron’s Book, by the way.</p>

<li>Also in the program is a taped discussion with the late choreographer George Balanchine and a performance by Patricia McBride and Edward Villella of the pas de deux from “Diana and Acteon”.</li>
</ol>

<p>Barron’s said the answer is “is”, which should be are because of the conjuction “and”. I thought it was “no error”, because I remembered the rule about a pronoun agreeing with the closer subject or something.</p>

<hr>

<p>Miscellaneous questions:</p>

<p>Is “who” a singular and plural pronoun?</p>

<p>Is a sentence redundant if it uses certain prepositions twice? (i.e - what are some of the known benefits of doing blah blah)</p>

<p>Anyone know of a comprehensive grammar website that can summarize this all for me? I’m taking SAT in Dec., and I’m aiming for a 100 point increase (690 → 790 - 800), but it’s seems to be more difficult than I’ve expected.</p>

<p>12) I did this question too. "are going" refers to the congressmen who are plural!
22) When "and" is used connecting the subjects the rule u mentioned does not apply since the subject becomes plural. Actually nor/ or applies to the pronoun closer to the verb agreement.</p>

<p>13) who can be both singular or plural I think
14) Not redundant but lesser the better.</p>

<ol>
<li><p>You don't need to maintain parallelism. "has been" should be "have been" since it's referring to critics.</p></li>
<li><p>I agree with you, thesmiths</p></li>
<li><p>Subject is plural. Does "Also in the program is Ben and Jake." sound right? No.</p></li>
</ol>

<p>Who is both.</p>

<p>No.</p>

<p>Dunno.</p>

<p>Nice for aiming high ^^</p>

<ol>
<li>The president has designated Senator Frank as one of the Congressmen who are going to attend the conference on nuclear waste disposal.</li>
</ol>

<p>"who are going to attend the conference..." describes "the Congressmen", not "Senator Frank"
Or, it could be said.. Senator Frank as one of the Congressmen, who is going to... since the latter phrase acts as a descriptive clause of Frank</p>

<p>Now that I look at it a second time, E is definitely correct.</p>
