1. Select the best of the answer choices given.
The interview is an essential part of a successful hiring program because, with it job applicants who have personalities that are unsuited to the requirements of the job will be eliminated from consideration.
The argument above logically depends on which of the following assumptions?
2. This question presents a sentence, part of which is underlined. Beneath the sentence you will find five ways of phrasing the underlined part. The first of these repeats the original; the other four are different. If you think the original is best, choose the first answer; otherwise choose one of the others.

1、The Correct Answer was:
(C) Interviewers can accurately identify applicants whose personalities are unsuited to the requirements of the job.
Explanation:
(A) The interview is an essential part, but not the only part of a successful hiring program.
(B) The argument does not address the importance of developing a job description.
(C) Correct. The interview can only eliminate those unsuited to the job if the personalities can be accurately identified.
(D) The argument states one thing that can be done with the interview, but does not imply that is its only purpose.
(E) The argument identifies a way to find people who are not a fit, but does not imply who will be the best fit. Furthermore, there is no information about past data on hiring decisions.
2、The Correct Answer was:
(B) significantly compounding the effects of drug and alcohol abuse, which already cost business
Explanation:
(A) are a cost to business is passive and not preferred.
(B) Correct.
(C) already with business costs of is awkward and wordy.
(D) significant in compounding should modify effects of drug and alcohol abuse so is awkward and wordy; use of and suggests it refers to the use of crack and cocaine when it should refer to the effects.
(E) significant in compounding should modify effects of drug and alcohol abuse so is awkward and wordy; use of and suggests it refers to the use of crack and cocaine when it should refer to the effects.
3、The Correct Answer was:
(C) Transnational cooperation has in the past been both more common and less common than it is now among United States firms.
Explanation:
(A) The passage does not provide information about the size of the projects or the reasons they choose to work collaboratively.
(B) The passage does not provide information about the reasons the projects are offered as transnational.
(C) Correct. That they are experiencing a modest renaissance implies that they are returning to favor after being out of style for a while.
(D) The passage states that they are less profitable than single projects, but does not imply that they are not profitable.
(E) The passage states that the joint projects benefit the United States firms, since they are awarded new contracts.
4、The Correct Answer was:
(C) Like Auden’s, James Merrill’s language
Explanation:
(A) Like Auden modifies language rather than the intended Merrill.
(B) Like Auden modifies language rather than the intended Merrill.
(C) Correct. With Like Auden’s the language is implied. It correctly modifies Merrill’s language.
(D) Auden needs to be in the possessive form to match with Merrill’s.
(E) Lack of parallel structure; Auden’s does not match of James Merrill.
5、The Correct Answer was:
(B) $175
Explanation:
Determine the food costs per person per day by dividing the total food cost of $60 by 4 adults and 3 days, (60/4)/3=(15)/3=$5. Then multiply by the food costs by the number of adults and days of the new trip, $5*7*5=$175.
6、(E) 280
Explanation:
6. If g is the number of rooms at Hotel G and h is the number of rooms at Hotel H, then the first part of the problem can be represented by the equation g = 2h-10 and the second part can be represented by g + h = 425.
Solve the system of equations by substituting for g in the second equation:
g = 2h – 10,g + h = 425,(2h-10) + h = 425,3h – 10 = 425,3h = 435,h = 145
Then find g:
g = 2h – 10, g = 2(145) – 10, g = 290 – 10, g = 280
The correct answer is E.
7、The Correct Answer was:
(A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Explanation:
7. The arithmetic mean of x and y can be represented as the sum divided by 2. Then the problem can be written as
Is (x + y)/2 > 20 which can also be expressed as x + y > 40
(1) Express the average as an equation and simplify:
(2x + 2y)/2 = 48, 2x/2 + 2y/2 = 48, x + y = 48, 48 > 40; SUFFICIENT
(2) Substituting for x in the inequality yields:
x + y > 40, 3y + y > 40, 4y > 40,y > 10
If y > 10, then the answer to the question is yes; if y < 10, then the answer to the question is no. Without additional information, the question cannot be answered. NOT sufficient.
Alternatively, you can substitute values of x and y that satisfy the condition x = 3y, and see if you find solutions that give you conflicting results:
If y = 5 and x = 15, then (x + y)/2 = 10, which is NOT greater than 20.
If y = 20 and x = 60, then (x + y)/2 = 40, which IS greater than 20.
The correct answer is A; Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
8、The Correct Answer was:
(A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Explanation:
8. For this problem, it is not necessary to determine the value of p, but merely whether p is prime (answer to the question is no) or not prime (answer to the question is yes).
(1) Possible values of p are 32, 33, 34, 35, and 36, all of which are not prime. SUFFICIENT.
(2) There are several possible values of p that are prime and others that are not prime. NOT sufficient.
The correct answer is A; Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
