<p>use “that” when the clause after it is necessary. “that” does not require a preceding comma.</p>
<p>use “which” when the clause after it is not necessary. “which” needs a preceding comma.</p>
<p>He bought a cookie from the store THAT is located on 8th ave.</p>
<p>vs</p>
<p>I recently received a package, WHICH was sent to me by my brother.</p>
<p>there is no rule that dictates if the clause after is necessary or unnecessary. That decision would be based on personal judgment.</p>
<p>^ I would add that “which” can be substituted for “that” in most cases.</p>
<p>Ah ok thanks. That makes sense.</p>
<p>Something of a phenomenon in the entertainment world, political satirists are admired by conservatives and radicals alike. No Error</p>
<p>I know the answer is either A or E. I think “something” is singular, so it can’t refer to “political satirists,” but then again it might be some sort of idiom… Anyone got an idea?</p>
<p>“something of a/an” is an idiom, but “something” here refers to “phenomemon”, which in turn refers to the second part of the sentence: political satirists are admired by conservatives and radicals alike</p>
<p>the following question is quoted from a GMAT forum.</p>
<p>"We have the comparative structure in the following sentences:
<p>Then we have a different comparative structure in the following sentences:
2. The blue dress looks more flattering on you than the red one does.
3. Sam was away on vocation longer than his friends were.”</p>
<p>Why can’t we use in the second and the third sentences the same the structure as in the first sentence, changing them as follows?
<p>Can someone tell me why is the answer E???</p>
<p>Some beaches are frequently contaminated by untreated sewage that flows into (the ocean, which can last for several days.)</p>
<p>A) ocean, which can last for several days
B) ocean that can last for several days
C) ocean, it can last for several days
D) ocean, while contamination can last several days
E) ocean; the contamination can last for several days</p>
<p>in the original sentence, “which” can only represent “ocean” since it is closest, so A distorts the meaning. B is wrong for the same reason. C is a run on sentence and “it” is vague. In D, “while” indicates an illogical relationship btw the two parts. E is correct as it uses semicolon to avoid being a run on structure, and “the contamination” is clear.</p>
<p>Thnx renlandrew. That kinda makes sense as I chose answer A without realizing that the option proves to be incorrect reference.</p>
<p>renlandrew, i have an iota of a solution for your question…</p>
<p>i think the first two cases can only be used with action verbs, whereas the last two are for helping/linking verbs. and yes, “looks” is a helping verb in that sentence because the subject is not doing any looking.</p>
<p>From the BB2, practice test 6, section 6, question 26</p>
<p>Mediators were standing by, prepared to intervene in the labor dispute even though both sides had refused earlier offers for assistance.</p>
<p>A: to intervene in
B: even though
C: had refused
D: for
E: no error</p>
<p>The answer is D, but I’m not sure what word should replace “for”. Should it be “of”? Just making sure.</p>
<p>Yes eastlaker, it should be of.</p>
<p>I just wanna say that the idea of making up this thread was a brilliant one.—Good job Silverturtle!</p>
<p>thanks Indianjatt</p>
<p>Some of the workers [who resent] the supervisor’s authority [would probably] feel uncomfortable [if] they were to acquire the independence that [they demand].</p>
<p>The answer is B, but doesn’t “will probably” make more sense?</p>
<p>Are you sure the answer is B? B looks fine to me because “would” should be used for verbs that are in the past tense (i.e. were is in the past tense in the conditional clause “Ifif] they were to acquire the independence that [they demand].” </p>
<p>I would say there is no error.
Is this from CB?</p>
<p>1) How is the word ‘whose’ used? Is it singular or plural, and when is it correct/incorrect? It always sounds awkward to me in sentences. </p>
<p>For example: The goals of the scientists, whose training had afforded them extensive experience with cutting-edge methodologies were to change the genetic components of the virus.</p>
<p>(there was an error near the end of the sentence, but it was glaringly obvious so I just omitted it.) Can anyone give me info about how ‘whose’ is used?</p>
<p>2) Had written vs. Wrote. What’s the difference, when to use which one?
Also, Had wrote and written are both incorrect, right? Just trying to confirm this one.</p>
<p>Thanks!</p>
<p>
</p>
<p>Haha my bad. I meant that there’s no error, but I THOUGHT it was B. But I still don’t understand why it isn’t “will probably”.</p>
<p>^ “were to acquire” is hypothetical. Thus, “would” should be used.</p>
<p>If the sentence were written, “Some of the workers who resent the supervisor’s authority will probably feel uncomfortable when they acquire the independence that they demand,” it would be correct.</p>
<p>Aeri, </p>
<p>“whose” is the possessive case of “who” and “which.” It can be use singularly or plurally.</p>
<p>For those who find conditional tense confusing, the following summary might be of some help:</p>
<p>Present Real Conditional
[If / When … Simple Present …, … Simple Present …]
If the weather is nice, she walks to work.</p>
<p>Present Unreal Conditional
[If … Simple Past …, … would + verb …]
If I owned a car, I would drive to work.</p>
<p>Past Real Conditional
[If / When … Simple Past …, … Simple Past …]
When I had a day off from work, I often went to the beach.</p>
<p>Past Unreal Conditional
[If … Past Perfect …, … would have + past participle … ]
If I had owned a car, I would have driven to work
Future Real Conditional
[If / When … Simple Present …, … Simple Future …]
If I find her address, I’ll send her an invitation.</p>
<p>IMPORTANT If / When
“if” suggests that you do not know if something will happen or not. “When” suggests that something will definitely happen at some point; we are simply waiting for it to occur.
When you call me, I will give you the address.
If you call me, I will give you the address.</p>
<p>Future Unreal Conditional
[If … Simple Past …, … would + verb …]
[If … were + present participle …, … would be + present participle …]</p>
<p>“Were to” in the Present and Future
[If … were to + verb …, …] “Were to” can be used in the present to emphasize that the conditional form is extremely unlikely or unthinkably horrible.</p>
<p>If she were to be rich, she would be horribly obnoxious.
IT IS VERY UNLIKELY THAT SHE WOULD BE RICH.</p>
<p>“Were to” in the Past
[If … were to have + past participle …, …]
If Sarah were to have failed the final test, she would have lost her scholarship</p>
