Hi,
I have been using the Manhattan GMAT SC book.The book suggests to use the "Splits and Re-splits" method. Through this system, you have to scan the answer choices vertically - without read them - looking for differences that split the answer choices. After that, you have to eliminate the splits which are wrong.

Ok, probably that method is Ok when you have a question in which the answer choices only are different in certain words, but what to do when you face a question like this? How effective is that approach when the choices are totally different?

His campaign for sanitary conditions in operating rooms finally successful, Sir Joseph Lister lent his name to the company that developed Listerine, the first antibacterial liquid.

(A) His campaign for sanitary conditions in operating rooms finally successful
(B) Since his campaign for sanitary conditions in operating rooms had been eventually successful
(C) Because of the eventual success of his campaigning for sanitary conditions in operating rooms
(D) His campaign for sanitary conditions in operating rooms being eventually successful
(E) Campaigning, eventually successfully, for conditions to be sanitary in operating rooms

When you see such large differences and so much underlined material, it is usually indicative of a modifiers issue. See what modifiers are being used and double check to see if they are being used correctly..
