(C) The author is not very opinioned in this passage. He or she simply tells the story of Tammany and provides related information on who was involved with it. Therefore, the tone of the passage is _object_ive. The author does not pass judgment on the corruption, and is not negative in tone, so (A) and (

are incorrect. The author also does not use language that is positive, so (D) is wrong, and (E) too. Reverent is an extreme choice. It would be hard to describe a corrupt political organization with reverence. (500)
5)
(D) The sentence explains that Tweed's regime, which includes both Tweed himself and his administration, was corrupt, and so brazen (bold) in its corruption, that his regime incited (brought about) attempts at government reform. (A) misconstrues the sentence to mean that Tweed called for the reform, when, in fact, others called for it to be made upon him. (

is partially correct, but does not go far enough. (C) is true but does not provide the correct meaning of the particular sentence in question. (E), like (A) misconstrues the sentence's wording. (600)
6)
(E) As we found in question 4, this passage is quite _object_ive. Therefore the purpose of the passage cannot relate to the author's opinion. Thus, (

and (C) are wrong. The author never argues for or against Tammany. (A) is more subtle, but still requires author opinion to be correct. In order for the author's _object_ive to be to honor Tammany's bosses, the author would have to praise them somewhere in the passage, and he or she does not do so. (D) does not contain opinion, but it is incorrect because there is no theory presented in the passage. It is simply a short historical piece, detailing Tammany's major figures and Irish involvement.
