GMAT Reading Comprehension Practice Test Answers

1. C
The third paragraph states that the Department of Homeland Security ‘argued that the new laws might actually limit protections for freedom of thought by . . . hampering the efforts of citizens to restrict their thought-processes to wholly legal topics.’ In other words, the laws would pose a legal problem for ordinary citizens by making it harder for them to precisely understand and obey the law.

2. A
The ‘review of thoughts’ refers to the provision in the law that sets up a Civilian Thought Review Council with the power to legalize new thoughts. If that council ‘does not have the knowledge required to judge whether a thought is dangerous or not’ as in choice A, a dangerous thought could be made legal, compromising national security.

None of the other choices has the potential to threaten security. Keeping threatening illegal thoughts that are no longer threatening, choice B, won’t endanger security, since all threatening thoughts would still be illegal. Similarly, the amount of resources the civilian board needs, choice C, doesn’t have any bearing on the impact of its decision. The government pressuring civilians not to legalize a thought, choice D, will not lead to dangerous risks, but rather to more conservative decisions. The veto power of the High Tribal Council, choice E, could actually be used to curtail anything dangerous the Civilian Thought Review Council does.

3. C
The fourth paragraph says ‘the president himself objected strongly to this, saying that the amendment would potentially expose huge numbers of government contacts and connections to public view unless the bureaucrats were able to show that each individual secret was exempt from the law.’ Clearly, he feels that having to show that ‘each individual secret’ is exempt is impractical.

GMAT Critical Reasoning Practice Test Answers

1. C
The question asks us to reinforce the conclusion that deceptive television commercials could cause consumers to be tricked into making a poorer health choice. For this to be true, we need to know that consumers actually believe what the ad says.

2. D
The correct answer will contradict the senator’s argument that legalization will reduce crime. Choices A and C address the rate of drug use, not the crime rate. Choice B talks about the budget. Choice E talks about legal alternatives to illegal drugs. Only choice D argues that more crime might be committed as a result of legalization.

3. D
The robot was thinking about crushing humans but in a passive recharging state. When the chip was removed, the robot began crushing humans without leaving the recharging state. This obviously implies that it was acting out a dream in the recharging state. If the chip removed were stopping commands from getting to the robot’s body, then without it the robot will act out its evil robot dreams.

4. C
The modern theory states that the Lothars, the Hill People, and other cultures influenced each other, and that modern Mucky Muck shows the influence of more than one society. Therefore, we are looking for evidence of cultural cross-pollination. Choice A doesn’t say that the cultures influenced each other, only that they both came from Central Europe. Choice B shows that the two peoples looked similar, but that doesn’t mean that they had similar cultures or even a lot of contact’”they may have evolved similar physical traits because they occupied the same environment. Choice D shows the two cultures diverging, not influencing each other. Choice E shows a difference between the two cultures but does not show them influencing each other. Only choice C shows cultural cross-influence. If a Mucky Muck myth incorporates a Hill People hero and a Lothar god, presumably the two cultures influenced each other to create the myth.

5. E
There are two possible causes for the increase in mutations: radiation and a higher population of thrill-seekers. The original statement argues that thrill-seekers are more prone to mutations, and therefore the rise in their population is the cause of the rise in mutations. If the factor that causes thrill-seekers to be prone to mutation is the radiation, it undermines the argument.

GMAT Data Sufficiency Practice Test Answers

1. C
We are trying to find y + z. (1) tells us that y = z + 16. Substituting, we get (z + 16) + z = 2z
+ 16. This expression can vary in value, so (1) is not sufficient.

(2) tells us that y + 10 = 2(z + 10) or y + 10 = 2z + 20. Thus, y = 2z + 10.

This expression can also vary in value, so (2) is not sufficient.

Given (1) and (2): y = z + 16 and y = 2z + 10, we can solve the equations simultaneously to obtain values of y and z.

Therefore, the correct answer is C; BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

2. B
The volume of a rectangular solid is lwh.

(1) gives us lw = 40. Substituting that into the volume formula, we get V = 40h. This expression can vary in value, so (1) is not sufficient.

(2) gives us lwh
= 30. Multiplying both sides by 2, we get lwh = 60. The volume is therefore 60 and (2) is sufficient.

Therefore, the correct answer is B; Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

3. E
(1) does not give us the net proceeds total for the first day, so it is not sufficient.

(2) does not give us the net proceeds total for the second day, so it is not sufficient.

Without the total net proceeds for either the first or the second day, we are unable to find the net proceeds for the third day.

Therefore, the correct answer is E; Statements (1) and (2) TOGETHER are not sufficient.

4. D
(1) Transposing like terms gives the equivalent equation ‘“4 = 10x, or x = ‘“. So, (1) is sufficient.

(2) Cross-multiplying gives ‘“10x = 4 or x = ‘“. So (2) is also sufficient.

Therefore the correct answer is D; EACH statement ALONE is sufficient.

5. A
(1) Using the Pythagorean Theorem, if a2 + b2 = c2 then the triangle is a right

52 + 122 = 132 or 25 + 144 = 169 is true, so (1) is sufficient.

(2) We know that x + y + z = 180. We are told that x = 45. Substituting, we get 45 + y + z =
180, or y + z = 135. If either y or z is 90 then the triangle is a right triangle, but we are not given enough information to determine this. So (2) is not sufficient.

Therefore, the correct answer is A; Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
