<p>Cola nuts are the caffeine-rich nuts of Cola auminata
and Cola nitida, evergreen forest trees that are
native to tropical West Africa and that are a member
of the same botanical family as cocas. No error </p>
<p>the answer is B, a member, because it disagrees with ‘trees’.</p>
<p>so is “…are an example” incorrect?</p>
<p>Cola nuts are the caffeine-rich nuts of Cola auminata
and Cola nitida, evergreen forest trees that are native to tropical West Africa and that are an example the same botanical family as cocas. No error </p>
<p>Do you think the sentence makes sense?</p>
<p>instead of “a member of,” it should be “members of.”</p>
<p>I’m sorry if I gave it away jamesford.</p>
<p>The answer B is correct because it does have an error.</p>
<p>The original sentence states: Cola nuts are the caffeine-rich nuts of Cola auminata
and Cola nitida, evergreen forest trees that are native to tropical West Africa and that are a member of the same botanical family as cocas. No error </p>
<p>After the comma, you have a phrase which serves to give more detail. You can tell that this phrase modifies both Cola auminata and Cola nitida because you see “evergreen forest trees” immediately after the comma. Consequently, the plural form must be used THROUGHOUT the phrase appearing after the comma. This explains why B has an error. “A member of” simply cannot be used for a plural subject (the Cola auminata and Cola nitida).</p>
<p>@jamesford
you are creating a new error in the sentence. “That are an example” cannot be correct because “are” is used for a plural subject and “an example” is singular.</p>
<p>The OP knew the answer. His question was</p>
<p>
</p>
<p>I typed out the sentence with the phrase “are an example” present to demonstrate that the sentence would not be correct with the new phrase.</p>
<p>i dont mean “…are an example” in place of the original sentence. i mean “…are an example” as a phrase (as in “Humans are an example of a civilized species”). how would you say it then, if there is a noun-noun disagreement?</p>
<p>If you have a plural subject:
you would have to say “are examples of…”</p>
<p>If you have a singular subject:
you can have to say “is an example of…”</p>
<p>^</p>
<p>It makes sense to say “Chimpanzees are a type of primate”</p>
<p>^so then why is “evergreen forest trees…are a member” wrong because of noun-noun disagreement (according to CB)? especially since both this and the chimpanzee example have to do with biological groups…</p>
<p>“Cola nuts are the caffeine-rich nuts of Cola auminata
and Cola nitida, evergreen forest trees that are
native to tropical West Africa and that are members
of the same botanical family as cocas.”</p>
<p>That’s the correction of the sentence I believe.</p>
<p>@jamesford
Even though it makes sense, it does not necessary mean its correct standard English.
@jamesford and crazybandit
Collegeboard believes that everything in the sentence should match, plural with plural, and singular with singular</p>
<p>the “evergreen forest trees” refer back to both “Cola auminata
and Cola nitida”. That is a plural verb. </p>
<p>However, I’m not sure. Can someone tell me the rule for this sentence:
X and Y, blah blah blah. </p>
<p>does the “blah blah blah” refer to “y”, or “X and Y”?</p>

<p>I remember a CB question is “children(plural) develop an independence(singular) that their parents can’t accept.” This sentence is correct.</p>
