<p>The electric fan was an ingenious invention for keeping people cool during the (summer; it was popular only briefly, however), until the air conditioner made it old-fashioned.</p>
<p>A. As it is
E. summer, but was popular only briefly</p>
<p>Answer: A. I chose E because it was more concise and less wordy. Kaplan says E is incorrect because it "incorrectly uses a coordinating conjunction and a comma to separate an independent clause and a dependent clause.</p>
<p>I played soccer to the point where I was extremely fatigued, but felt healthy.
So, the above sentence is wrong (if coordinating conjunctions don't link independent and dependent clauses)?</p>
<p>Another question:</p>
<p>The strict training schedule allowed the marathon runner to eventually run for 20 miles (and she could scale) steep hills without stopping for rest.
B. as well as scale
E. and to scale</p>
<p>If B were “as well as TO scale”, the answer would’ve been correct, because of parallelism?</p>
<p>Another one:</p>
<p>Primarily a strategy to attract the votes of the elderly, the social security adjustment carried great weight among the entire voting public of the day.
A. As it is.
B. Primarily a strategy of attracting the votes of the elderly</p>
<p>Why is B wrong? Would it be eliminated because it slightly alters the meaning of the sentence by no longer attributing the attraction of votes to the purpose of the strategy, but attributing to the strategy itself, such that the strategy is the attraction of the votes?</p>
<p>lol Kaplan. Don’t use it for the regular SAT. The question in your first post is sort of BS and I think either A or E could be correct.</p>
<p>As for the second question, yes, I think B would be correct if it was that way.</p>
<p>B is wrong because “Primarily a strategy to attract the votes of the elderly” is a dependent clause and you need the comma because the dependent clause is coming before the independent clause, or else it cannot stand. </p>
<p>I admit I’m not familiar with all the grammatical terms but I hope it helped a little.</p>
<p>No I think that the comma wasn’t the problem. Either the underlined part didn’t include the comma or I forgot the comma in choice B.
I think the explanation that choice B alters the meaning is plausible. Don’t you agree?</p>
<p>If the comma was already there then the explanation you mentioned is probably alright.</p>
