thats precisely what i thought. There is no flaw as such because : "...My recent reevaluation of Westinghouse, facilitated by materials found in railroad archives..." there is a discovery of a new fact which encourages a fresh perspective. E it is.

"What pushes most biographers on in this endeavor is not necessarily affection for the subject but the feeling that they are writing a good book." should be a consideration in choosing D

I think D is the right choice. If we leave apart the OA for a while we can very well see that the choice D is the right choice. there is a difference between will be and would.

I think again the concept modifier will apply over here. B modifies the subject properly.

It is a typical modifier question. what modifies and what is modified is to be seen. D is the right choice.

I think it should be A. OA please !!!!!!!!!

well well its an OG question..... the portion after the comma modifies the Architects and stonemasons....

its an idiom "credited ...with..."

A referent is not required in the present case. The usage of "..they.." makes D redundant E is the best choice.

Can anyone please explain this one ??? Thanks

I guess a case of subject-verb agreement the choice is C.

Well mehrak there is a big difference between D & E. In E the subject is the Persons unlike D where the subject is the hemolytic anemia.

E is the correct choice as it correctly includes "while........ "

I agree with star 321. the answer should be C. OA please !!

My answers are the same as DMoney:- B C D A. Question no.1 has to be answered by reading the whole passage. "therefore, one explanation is that cub-carrying is necessitated by myrmecophagy," "An alternative explanation........." these helped me in reaching my answer. Question 2. ".......and are often confronted and chased by rhinoceroses and elephants, which can topple trees. Collectively these factors probably selected against tree-climbing as a defensive strategy for sloth bear cubs." this was my base for answering this question. Question 3. "... Furthermore, the daily movements of sloth bears and American black bears which are similar in size to sloth bears and have similar-sized home ranges reveal similar travel rates and distances, suggesting that if black bear cubs are able to keep up with their mother, so too should sloth bear cubs.." this is the author's argument and we have to weaken it. As per me choice D does the job. Question 4. "....Like brown bears and polar bears (and unlike other myrmecophagous mammals, which are noted for their passivity), sloth bears are easily provoked to aggression...." Easily suggest the choice of A.
