After going through the post of various people, I am still confused between B and C.FIRST OF ALL JUST TO INFORM ALL
S-V error is corrected in B and C. option B uses Each in non-essential part of the sentence and option C uses all in essential part of the sentence. Can this be the make or break rule on GMAT. I request experts to comment
: THIS IS NOT AN OFFICIAL QUESTION
NOW IN OPTION B,C the difference is what is used between dashes.
we can keep 3 things between the dashes(as per RON):(CHECK THIS OUT :http://www.manhattangmat.com/forums/use-of-hyphen-t3070.html
)1) dashes can be used in the place of commas, to express some degree of surprise or irony at the content of the modifier that is being set off.
john, who is from las vegas, complained that winters in san francisco were cold.
there is no degree of surprise or iron into this modifier, so it is set off with commas as usual.
john -- who is from alaska -- complained that winters in san francisco were cold.
this modifier has a great deal of irony/surprise (for readers from other countries, alaska is much, much colder than san francisco). therefore, the modifier is set off with dashes, because its content is ironic or unexpected.
this is not the use of the dashes in the above examples.(2) dashes may also be used as a substitute for commas to set off a modifier that NAMES people or things, especially if there is a LIST of such people/things.
three of the players -- john, joe, and sammy -- and their wives were absent from the team banquet.
--> in this sentence, it's actually imperative that we use the dashes, since the sentence would be ambiguous if you just used commas:
three of the players, john, joe, and sammy, and their wives were absent from the team banquet.
there are two possible meanings for this version: (a) three unnamed players, john, joe, sammy, and all six of their wives; or (b) the above intended meaning.this is more along the lines of what they are doing in the problems cited above. unlikely example that i have just given, those sentences are not ambiguous without the dashes, but the dashes help them become much more readable.3) dashes can be used to replace colons.
a dash can be used in essentially any context in which one would normally use a colon.
i believe that this would normally be done when there is an element of irony or surprise, or perhaps emphasis (much as in example #1 above).IN OPTION B there is a wrong usage of DASHES.hence this is wrong.NOTE
: GMAC dosent tests on PUNCTUATIONS.
hope this helps.
