Here is my analysis:

Knowing the rules of FANBOYS is very important:

1) FANBOYS signals parallelism- I eat and sleep. (Notice no comma before "and")
2) FANBOYS- if there is a comma before FANBOYS, an independent clause must be present.

A) See the comma before "and"---wrong way to apply the rule (see #2)
B) For parallelism, no need comma before "and"
C) Looks good as it follows the rule (see #1)
D) Notice which is not a good use for this sentence-powered is not the right discussion in the original sentence.
E) No comma before "and"--- must be parallelism but it turns out that they blah blah is independent clause--SO in order to be true, there must be a comma before "and"

Hi experts,

In choice E, I know "they are" is unnecesarry and that of is incorrect, but does the presence of "they are" (SV) demand a comma before "and", making this issue another reason why E is wrong?

Kind regards,
Cristián



Hello Cristián CristianJuarez,


I will be glad to help you out with this one. :-)

Yes, your your analysis of the structure in Choice E mentioned in your post is absolutely correct.

Since therefore they are... is an independent clause, the connector and must be preceded by a comma to connect this clause to the preceding independent clause.


Hope this helps. :-)
Thanks.
Shraddha

Hi Experts
Is below analysis correct, look forward to your insights!
A & B: On striking off the modifier , almost all of which are gasoline powered, the sentence does make sense
Core of A: it will have no effect on sport utility vehicles,almost all of which are gasoline powered, and will not be subjected to emissions-control standards as stringent as they are for diesel-powered vehicles.
Core of B: it will have no effect on sport utility vehicles, almost all of which are gasoline powered, and therefore not subjected to emissions-control standards that are as stringent as those of
We can also say that nothing is parallel before and when modifier struuck off in A and B, so can be eliminated.

Why is D wrong? What does which refers to?

Thanks in advance!

Though the law will require emissions testing of all diesel vehicles, from tractor trailers to excursion buses, it will have no effect on sport utility vehicles, almost all of which are gasoline powered, and will not be subjected to emissions-control standards as stringent as they are for diesel-powered vehicles.

If the bold part above remains in comma pair, it becomes a modifier and thus the phrase, "and will not be subjected to emissions-control" will incorrectly modify the pronoun "it", whose antecedent is law.

Second important differentiation here in in the idiomatic use of "As stringent as those of/for". The standards are for vehicles and not of vehicles.

Hence, Of possible answer choices A,C and D(using for) , only C uses the modifier correctly and correctly phrases the overall sentence.

Hence, C

Thanks in advance!

Here's the relevant portion of (D) again:

    "...it will have no effect on sport utility vehicles, almost all of which are gasoline powered, which are not subject to emissions-control standards as stringent as they are for..."

There are two conspicuous problems here. First, the second "which" likely refers to the same noun the first which does -- in this case, "sport utility vehicles." If we're going to use two "which" modifiers this way, we'd need to link them with a conjunction: "which x AND which y."

Also, notice the "they" in blue in (D); (C), on the other hand, uses "those." Generally, we'll use "they" to invoke a previously mentioned noun, and "those" to introduce a new noun (in a sense, to "create a copy" of a noun) we'd like to compare to the earlier one. For example:

  • "Tim's twins are taller this year than they were last year, undermining whispers that he does not feed his children." -- In this instance, it's the same set of twins we're discussing, so "they" is appropriate.
  • "The twins in Tim's family are taller than those in Mike's family, leading to a new set of accusations that Mike does not feed his children." -- Now, "those" refers to a different set of twins, as opposed to the same twins mentioned earlier.

Here, it makes sense to use "those." We're comparing one set of standards (for gasoline-powered vehicles) to a different set of standards (for diesel-powered vehicles.) The use of "they" makes it sound as though the standards for gasoline-powered vehicles are also used for diesel-powered vehicles. This makes no sense. How could one set of standards be more stringent than the other if they're the same? So (D) is gone.

I hope that helps!
