<li><p>The wording should be “emphasis on” rather than “emphasizing on.” Although “emphasizing” is a gerund (a verb-form ending in “ing” that is used grammatically as a noun), “emphasizing” takes a direct object [stating what is emphasized]. It does not use “on.” The noun “emphasis,” on the other hand, is often followed by “on” and then a statement of what is being emphasized.</p></li>
<li><p>The main predicate in this sentence is “reduces CO2 production.” It needs a subject. The phrase “when you are not using it” modifies the subject of the sentence, so you can drop it when you are trying to determine the correct choice for the subject. “By unplugging” is a prepositional phrase, and therefore it is not the subject. In contrast, “unplugging” is a gerund (verb form used as a noun), so it can be the subject, and C is the correct choice.</p></li>

<p>thanks! I have some other questions:
1.Once American films looked slick and commercial compared to European imports;( now, almost the reverse is true).
A. now, almost the reverse is true
B. now they are almost the reverse
C. instead, there is almost a reverse now
D. now it is almost the reverse that is true
E. it has now been almost reversed</p>
<p>the correct answer is A, but I chose B. I think each choice is really confusing. I learned that sometimes, ponouns are wrong if they are kind of misleading to the readers, so why is A correct?</p>
<p>2.The refusal of the management (to revise) (their) (policy on) family love (caused) an uproar among employees.( No error).
The correct answer is B, but I chose E. there is no word or phrase in this sentence that indicate what tense should it be, right? Then how can I know which to use? And why is B correct?</p>
<p>3.(From 1566 until) 1576 Santa Elena, now an (excavation site) in South Carolina, was the capital of Spanish Florida; (however), it (has become) an English settlement by 1735.(No error)
The correct answer is D. I chose it, but I don’t know why choose D. is it like when I see the word “by”, I should use past perfect tense?</p>
<p>(With billions of tons) yet to be mined, some argue that coal conservation measures are unnecessary.</p>
<p>a) With billions of tons
b) Because billions of tons of coal are</p>
<p>Why a) is wrong and b) is right?</p>
<p>What’s the difference between “your” and “you’re”?</p>
<p>:-)</p>
<p>lolipoppy,
- “they” is wrong because it refers to American films. When you put it to the sentence “now American films are almost the reverse”, it makes no sense.
- “The refusal of the management to revise ITS (the management’s) policy”.
- I don’t know this one.</p>
<p>lolipoppy:
For 3, the last year given is 1735, indicating past. The correct answer is D because it would be “it had become an English settlement by 1735”</p>
<p>AimingAt750:
I always think of “because” as “since”. Although its not technically correct, it has helped me out a lot on the SAT’s. Now read the sentence again. “Since billions of tons of coal are yet to be mined, some argue that coal conversion measures are unnecessary.” This choice makes more sense than choice A because it has the “Since _____ has happened, _______ is not the correct choice”, which seems to be a better fit. Just how I would tackle the problem, hope it helped a bit! </p>
<p>Keeyano:
Lol not sure if serious or not…but “your” indicates possession. You would say, “Your average SAT scores are…” not “You’re average SAT scores are…”.
You’re is simply you are. You would say, “You’re going to do great on the SAT’s!” not “Your going to do great on the SAT’s!” which is where a lot of people make a mistake.</p>
<p>How do you know that “they” doesn’t refer to “European imports”? thanks for the other answers.</p>
<p>Really quick question:
The Boston Red Sox has/have finally won a world series.</p>
<p>This is a question from Barron’s book.</p>
<ol>
<li>Many alcoholics attempt to conceal their problems from their fellow workers, (but invariably failing to keep their secret.)</li>
</ol>
<p>I narrowed down the options to:</p>
<p>B. but they invariably fail to keep their secret.
C. but fail, invariably, to keep their secret.</p>
<p>B is correct. However, I wonder why the ‘they’ in B isn’t deemed “ambiguous pronoun reference” since it could refer both to the alcoholics and their fellow workers. Barron’s says invariably in C sounds awkward. What exactly makes it awkward?</p>
<p>I’ll be grateful if someone can take out some of his/her time to answer. :)</p>
<p>thanks for the tip, 5am6996, I just did another practice test and thinking of “because” as “since” has helped me to find the correct answers quickly.</p>
<p>lolipoppy, the subject of the sentence is “American films”: Once American films looked slick and commercial. This would be enough to make a sentence. “compared to European imports” is just an additional detail.</p>
<p>yellowcat429, you should treat The Boston Red Sox as singular. It is a team. Therefore you use “has”. Add the word “team” to see how it works: The Boston Red Sox team has finally won a world series.
I don’t know how to explain the other one. I just feel that it doesn’t work among the commas, like it is out of place. Try to replace it with “always” and see how the sentence <code>doesn’t flow</code>: but fail, always, to keep their secret.
To see how “they” isn’t ambiguous, remove the additional information and just keep the main sentence to see clearly that alcoholics are the subject of the sentence: Many alcoholics attempt to conceal their problems, but invariably fail to keep their secret. <code>from their fellow workers</code> is just an additional detail.</p>
<p>That helped!
As for your question AimingAt750, may be it would help to know that “with” isn’t normally used a subordinating conjunction. The most common SAT ones are: </p>

<p>From the BB:</p>
<ul>
<li>The exchange between the teacher and the student (promotes) learning (far different) from that which results (as) the student listens (but does not) participate. (No error).</li>
</ul>
<p>The correct answer is C : ‘as’. Why so? I thought that B was the error since it’s an adverb for the verb ‘promotes’ and should thus be ‘far differently’ instead.
Can anyone explain why B is correct while C is not?</p>
<p>From my point of view “as” is used incorrectly. It should be “when”. Edited version of the sentence to clear the meaning:
Promotes learning (that is) far different from that when the student listens but does not participate.</p>
<p>Always try to remove unimportant details from the sentence. The error is always somewhere in the main part unless the detail is used incorrectly.</p>
<p>I understand. 
Thanks!
When is using ‘as’ considered appropriate then? 'Cause I read ‘as’ should not be substituted for ‘since/because’ and as this last question proves, for ‘when’, too.</p>
<p>For the question “Same is a professor of theoretical physics, (while his brothers are architects) with outstanding reputations” why does “and” have to replace “while”? </p>
<p>Also, when is it correct to use “who” instead of “whom” even when it is an object? For example, the problem I was looking at said that it should be “A reward was offered to whoever would return the dog to its owner,” not whomever.</p>
<p>Thanks :)</p>
<p>‘While’ is most commonly used to indicate two things happening at once. e.g. “I did my homework while watching T.V.” It is a common subordinating conjunction. e.g. “While watching T.V., I did my homework.”
Over here, you’re trying to link two independent clauses using a coordinating conjunction. Common coordinating conjunctions are: and/or/nor/but/yet/so/for. So, “and” is most fitting. :)</p>
<p>Always use who/whoever when it refers to a subject. If a sentence has two verbs, look for two subjects. Here, “whoever” is correct because it is the subject of the verb “return”.</p>
<p>Surface mining is safer, quicker, and cheaper than deep mining, but (the greater is its toll in human misery).</p>
<p>B. it has a greater human misery toll
E. its toll in human misery is greater</p>
<p>Which is correct and why?</p>
<p>E ? because “in” is a preposition stating what type of toll (human misery) and human misery in front of toll in B is stated as if it were a common phrase, i.e. “human misery toll.” I’m guessing that this in turn in implying that human misery toll is one word, and it really isn’t. </p>
<p>That’s probably completely wrong though.</p>
