E.

Since we are only talking about cables, we should be looking for Unlike most cables...

THis leads us to C...but this would be a very strange sentence by repeating "protection from corrosion" two times.

D looks good, but requires is incorrect, should be require.

Hence E

Re: Unlike most suspension bridges, the main cables of the [#permalink] New post   17 Mar 2007, 08:36
I say D

you need the correct comparison

only D & E have this

it should be requires

galvanized wire REQUIRES

since the which clause modifies the galvanized wire it makes sense that require should refer back to the wire, not the cables so therefore singular

only D and E uses correct comparision. Now between D and E i choose D because which is a relative pronoun which modifies unglavanizes wire, which is singular. So the verb should be requires. Hence my answer is D.

I pick D for the singular use of require. Another tip: the word "which" almost always refers to the word right before. Hence, it refers to the wire, not cables.

Note the last fragment of the sentence that has not been underlined: "protection from corrosion". What requires protection from corrosion? The main cables, because they are not galvanized. The bridge per-se does not require any protection.
"main cables" is plural, so takes a plural verb "require"

Hence "E", not "D"

I find it difficult to see what now requires protection from corrosion- logically, this would be the cables, not the ungalvanized wire. C is the only one that makes sense to me

Agree with trivikram.
In C, "they" has been used ambiguously. It is not clear whether "they' refers to "most suspension bridges" or to "main cables"

I have no idea about this. Why not " the wire requires protection from corrosion" ?

The way which is used, it can not refer to main cables in GMATland. Logically main cables require protection but in that case "which" in (E) should be replaced by an "and". my 2 cents not even worth of a cup of coffee :)

Here it is - the OA is "C" and the OE is -

The main subject is not suspension bridges but about their main cables; it is cables which require protection, hence the sentence has to be rewritten. Hence, (C).

Think you GMAThopeful for posting OE, But if you put (C) into sentence, it will be
"Unlike the main cables of most suspension bridges those of the eighty-year-old Williamsburg Bridge now require protection from corrosion as they are made of ungalvanized wire protection from corrosion. "

I think that a "," should be added before "those" and that "protection from corrosion" is rendundancy.

Anyway, I will go to visit friends this weekend and come back on Sunday. So, wish all of your guys have a good weekend. :flower

IMO E

A and B are out because of incorrect comparison.

D is out because it uses singular "requires" for plural "mail cables"

in C "they" looks ambiguous.

D, see reasons within the quote.

What's the OA Suresh?

Answer Choices :

(A) most suspension bridges, the main cables of the eighty-year-old Williamsburg Bridge are made of ungalvanized wire, which now requires
The phrase "unlike most suspension bridges" is a modifier. What does it modify? According to this answer, the phrase modifies "cables". This is incorrect.
(B) most suspension bridges, the eighty-year-old Williamsburg Bridge's main cables are made of ungalvanized wire, which now requires
At first glance, this appears to correct the problem from A, but it doesn't. Williamsburg Bridge's is possessive and so Cable is the noun being modified...again!
(C) the main cables of most suspension bridges those of the eighty-year-old Williamsburg Bridge now require protection from corrosion as they are made of ungalvanized wire
The "Unlike...bridges" is still a modifying phrase and should be set off with a comma before "those".
(D) those of most suspension bridges, the main cables of the eighty-year-old Williamsburg Bridge are made of ungalvanized wire, which now requires
This fixes the modification issues in the prior answers. Also, the word "which" refers to "ungalvanized wire". This is a singular noun so the verb needed is "requries".
(E) those of most suspension bridges, the main cables of the eighty-year-old Williamsburg Bridge are made of ungalvanized wire, which now require
This fixes the modification issues in the prior answers but in a different way. Also, "require" is only correct if "which" refers to "main cables", otherwise "which" refers to "ungalvanized wire" and this is a singluar verb that needs "requires", not "require".

Answer Choices :

(A) most suspension bridges, the main cables of the eighty-year-old Williamsburg Bridge are made of ungalvanized wire, which now requires -> mismatch

(B) most suspension bridges, the eighty-year-old Williamsburg Bridge's main cables are made of ungalvanized wire, which now requires -> incorrectly compares bridges and bridge's attributes

(C) the main cables of most suspension bridges those of the eighty-year-old Williamsburg Bridge now require protection from corrosion as they are made of ungalvanized wire -> wordy and ambiguous they

(D) those of most suspension bridges, the main cables of the eighty-year-old Williamsburg Bridge are made of ungalvanized wire, which now requires -> this is incorrect since it says protection for ungalvanised wir but actually protection is meant for main cables made of these wires

(E) those of most suspension bridges, the main cables of the eighty-year-old Williamsburg Bridge are made of ungalvanized wire, which now require -> IMO E

If what you say is true regarding "which" then it breaks the rules of grammar. The word "which", when used to introduce a modifying phrase, refers to the nearest noun preceeding it. This would be "galvanized wire", not "main cables". Therefore, D is correct.

The correct method to make the phrase beginning with "which" modify "main cables" is as follows:
"Unlike those of most suspension bridges, the main cables of the eighty-year-old Williamsburg Bridge, which now require protection from corrosion, are made of ungalvanized wire."
