<p>TV weather forecasters sometimes overdramatize the severity of an approaching snowstorm, [causing] segments of their audience unnecessary anxiety </p>
<p>TV weather forecasters sometimes overdramatize the severity of an approaching snowstorm, [which cause] segments of their audience unnecessary anxiety</p>
<p>The first version is correct, which I got by ear. Is the second one wrong because "which cause" supposed to be "which causes"? I was unsure because I did not know what "cause" was supposed to match with</p>

<p>Ancient documents [wrote on] vellum, a for of fine parchment made of animal hides, must be stored under carefully controlled conditions</p>
<p>By ear, I knew that "wrote on" is wrong. It should be "written on." However, I know that the conjugation of the verb to write is "write" (simple present) "wrote" (simple past) and "have/had written" (past particaple). In this case why wouldn't the simple past work? Why must it be "written" ?</p>

Interest [to revive] the ancient Olympic Games as an international event grew when the ruins of the ancient city of Olympia were uncovered. </p>
<p>I knew "to revive" was wrong but why. It's a very subtle error and I want to make sure I don't accidentally miss these in teh future - what is the error and why? Are there more exampels of this?</p>
<ol>
<li><p>It needs to be “were written on” or something. That’s a misplaced modifier or something like it, the documents didn’t actually write anything.</p></li>
<li><p>Idk about the specific error here, it’s just a bad use of an infinitive and it seems unidiomatic. </p></li>
</ol>
<p>“Interest in reviving” probably is what should’ve been there.</p>
<ol>
<li><p>The over dramatizing causes the anxiety, not the forecasters. </p></li>
<li><p>“Must” implies the subjunctive tense, and so ‘written’ is needed to fulfill that.</p></li>
<li><p>“Interest in” is the proper idiom, not “interest to” saying that “I have an interest to go eat breakfast” sounds awkward, one says “I have an interest in eating breakfast.” - which is what I’m going to go do.</p></li>
</ol>
<p>For 1: it is not clear to whom or to what which refers to. Therefore, it is wrong.</p>
<ol>
<li>It is causing because first of all, you want to make your answer short as possible and second of all you should avoid using which IF POSSIBLE (don’t choose the wrong answer because of this) because which is probably the most ambiguous word on the SAT. </li>
<li>It sort of sounds like the documents itself wrote, and written on serves the purpose of the passive voice because it is the documents that are being “written on.” (Yes, the passive is sometimes okay to use.)
3.And honestly, I was stumped by this too but it seems that the proper idiom is “interest in.” Beats me.</li>
