Explanation:

Sometimes the simplest arguments prove to be the toughest questions. The conclusion is that the new bill will almost surely fail to pass. The evidence is that the leaders of all major parties have stated that they oppose it. In order to strengthen this argument, you need to find a statement that most accurately describes the situation in which this bill finds itself. In other words, you need to stay within the scope. At Kaplan, we'll teach you one of the most classic wrong answer traps on the LSAT is the “out of scope” answer choice. Let's take a look at our options:

(A) says that most bills that have not been supported by even one leader (that's the same as our bill, which is opposed by leaders of all major parties) have not been passed into law (which is what our conclusion predicts—that the bill will fail to pass). Therefore (A) is correct.

(B) is tricky. But it doesn't strengthen the argument because it describes the characteristics of bills that have not been passed into law; we're trying to predict what will happen to a bill that is not supported by leaders of any major party. (B) supports the notion that failing bills are unsupported, but we're looking for a choice that says that unsupported bills will fail.

(C) provides evidence about a bill that has the endorsement of the leaders of all major parties; that doesn't help us to support the predicted fate of a bill without any endorsement.

(D), if anything, weakens the argument by suggesting that a law can be passed without extensive support.

(E) The fact that most bills that have been passed into law were supported by at least one leader doesn't really tell us anything about what will happen to a bill not supported by any leader.

Inference questions—particularly those that involve elements of formal logic—are among the most complicated, yet most frequently tested, question types on the Logical Reasoning section of the LSAT. But not to worry. At Kaplan, we'll teach you how to deconstruct all argument structures in Logical Reasoning and the rest of the LSAT, and delve deep into answer choice construction, so you'll know exactly why right answer are right and wrong answers are wrong. You'll leave confident in your approach to LR on Test Day.
