</ol>

<ul>
<li>The error is (has recorded) and I got this right, but I don’t know how to fix this!!</li>
</ul>

<p>Please help!!! And thanks for reading this!!</p>

<p>1) “:” just mean to explain for the previous phrase. in this case, being rescued by a helicopter during a fire is a reason for how the students found fieldwork dangerous than they had thought.
2) I also think B. It uses exact inversion for the singular noun a crooked line ( singular verb runs)
3) I am not sure of this: whereby is never followed by a comma.
4) The sentence feels like missing verb??? I don’t know
I think it should be like:
The method of how different viruses ARE transmitted from one patient to another depends on the particular viruses involved.
Or
The method by which different viruses are transmitted from one patient to another depends on the particular viruses involved.
About “being” problems on SAT, actually, not all sentences including being are wrong.
Ex: Being an engineer, she is also blablabla
instead of " she is an engineer, and she is also …", This being is vital in this sentence.
5) It should be “had recorded”
THe act of recording happens before the act of performing a song so we should use the tense of past perfect.</p>

<p>(1) I don’t ever recall seeing the real SAT testing for punctuation, especially a colon. That said I agree with hanngo’s explanation</p>

<p>(2) B is right. The subject is line, and line is singular. So A is wrong – i.e. subject-verb disagreement. C is wrong because it doesn’t make sense for trees to be the subject. And even if it did make sense, there is subject-verb disagreement. For D & E when you drop the there you have either an illogical subject or a subject-verb disagreement.</p>

<p>(3) At best, whereby is a redundant conjunction. At worse it doesn’t make sense. Whereby should be followed by some statement that explains something. As written it serves as another “and”. The punctuation is not the issue.</p>

<p>(4) The sentence (ignoring the clause “of how …”) has a verb – i.e. depends. The method depends on <something>. Idiomatically we don’t say “the method of how”. We would say “the method by which”, so (A) is wrong. But the participle “being” in B doesn’t belong. Have you transcribed this choice correctly?</something></p>

<p>Thank you so much!!!
Actually number 4 question’s answer is wrong it should be “by which different viruses are transmitted” instead of “by which different viruses that are being transmitted”!
And I have another question, someone told me that the difference between " ; " and " : " is that afer " ; " there should be (must be) clause, but after " : " it can be phrase, or anything can come up after " : " is it true???</p>

<p>The “;” is little more than a “weak” period. What follows the semicolon is an independent clause. Often a semicolon can be replaced by a period. The use of one or the other is sometimes subjective – i.e. the whim of the writer. The text following the colon can be a list of items. (Google <grammar colon=""> for many explanations and examples.) I don’t recommend that you start using colons in your school writing. They are quite specialized.</grammar></p>

<p>In any case I assume that you are studying for the SAT. Distinguishing the correct use of periods versus semicolons versus colons is not the best use of your study time. This is not an area that’s tested.</p>
