299 Top #14 (A) explanation This choice states that the high quality … how vulnerable the public is to such disease. This choice strengthens the argument by making it clear that the “high quality of American hospitals” actually does have some (positive) relationship to the public's vulnerability to infectious disease. Mitigates means “to make less severe.”
305 Bottom #25 answer and explanation 25. (D). The letter writer…[entire explanation, which refers to a different question]

25. (B). This question is an Analyze the Argument Structure question; the best approach is to identify the conclusion, and then check each boldface portion of the question for how it relates to the conclusion, and eliminate incorrect answer choices on that basis. Here, the second boldface is the conclusion of the argument, as highlighted by the use of the signal word “Therefore.”

(A) The first boldface is not an assumption, as assumptions are, by definition, unstated. Also, the second boldface does not just describe the argument’s recommended position, it is itself the conclusion of the argument.

(B) CORRECT. The first boldface is a consideration that helps explain why companies charge as much as possible for new designs. The second boldface presents a different strategy endorsed by the argument, of charging less than the greatest possible price to maximize profit.

(C) The first boldface is not an assumption, as assumptions are, by definition, unstated. The second boldface is not the strategy referenced in the first boldface, as this answer choice suggests.

(D) The first boldface does not demonstrate that the strategy of selling for the greatest price will not apply, but instead supports it. Also, the second boldface is the argument’s conclusion itself, not a factor in support of it.

(E) The description of the first boldface is accurate; however, the second boldface is not a factor against the strategy of maximizing profits by charging the greatest possible price, but an alternative strategy altogether.

The uppermost portion of the fraction, 1/1, is just equal to 1. 557 Middle #11 explanation {Fraction bars do not match those in the question itself.} {cut the first fraction} 557 Bottom #11 explanation Dividing by 1/5-2 is the same…{erroneous fraction}…the answer is simply 52, or 25. Putting these together, the original fraction can be simplified. {Fraction from the question} = 1/52 = 1/25, which is the final answer. 586 Middle #38, end of explanation Since x + y = 11, y = 9 and Quantity B is greater.

To calculate first find the squared differences between the average and the terms. For example, the difference between the average, 4, and the first term, -1, is 5. 52 = 25. Do this for all four terms. 47. 18.2. To calculate, first find the squared differences between the average and each of the terms. For example, there is a difference of 4 between the average, which is 3, and the first term, which is -1. The square of this difference is 42 = 16. Repeat for the other three terms. 1044 Bottom #47 explanation –1: (4 – (–1))2 = 52 = 25 –1: (3 – (–1))2 = 42 = 16 1044 Bottom #47 explanation 4: (4 – (0))2 = 42 = 16 4: (3 – (4))2 = (–1)2 = 1 1044 Bottom #47 explanation 30: (4 – (30))2 = (–26)2 = 676 30: (3 – (30))2 = (–27)2 = 729 1044 Bottom #47 explanation –21: (4 – (–21))2 = (25)2 = 625 –21: (3 – (–21))2 = (24)2 = 576 1044 Bottom #47 explanation Add all of these terms together: 25 + 16 + 625 + 676 = 1,342. Add all of these terms together: 16 + 1+ 729 + 576 = 1,322. 1045 Top #47 explanation Take the square root (use the calculator!): Square root of 1342 = 36.633. Using the calculator, divide by the number of terms to get the variance: 1,322/4 = 330.5. Then take the square root to get the standard deviation of the set: square root of 330.5 ≈ 18.1797. 1045 Top #47 answer …round to the nearest tenth, so the answer is 36.6. …round to the nearest tenth, so the answer is 18.2. 1156 Top #13 …scould be the value of m? …could be the value of m? ## 1.1 Page Location Description Erroneous Text Correction 57 Middle #55 …try to cross the Rockies too late… …try to cross the Sierra Nevada too late… 229 Middle Passage, 2nd line …self-promotion is was evident in his choices… …self-promotion was evident in his choices… 269 Top #14 (A) …is not a factor affecting the public's vulnerability to infectious disease. …mitigates the public's vulnerability to infectious disease. 303 Top #14 (A) explanation This choice states that the high quality … how vulnerable the public is to such disease.
