Clark must have known that his sister Janet and not the governess pulled the trigger, but he silently stood by while the jury convicted the governess. Any person of clear conscience would have felt terrible for not having come forward with the information about his sister, and Clark lived with that information until his death 30 years later. Since he was an extremely happy man, however, I conclude that he must have helped Janet commit the crime. Which of the following assumptions must underlie the author's conclusion in the last sentence?

  1. Loyalty to members of one's family is conducive to contentment.

  2. Servants are not to be treated with the same respect as members of the peerage.

  3. Clark never had a bad conscience over his silence because he was also guilty of the crime.

  4. It is better to be a virtuous man than a happy one.

  5. It is actually better to be content in life than to behave morally toward one's fellow humans.


Correct Option: C
Explanation:

(3) Clark was unhappy if he had a clear conscience but knew, or Clark was happy if he knew but had an unclear conscience. It is not the case that Clark was unhappy, so he must have been happy. Since he knew, however, his happiness must stem from an unclear conscience.

Politicians are primarily concerned with their own survival; artists are concerned with revealing truth. Of course, the difference in their reactions is readily predictable. For example, while the governmental leaders wrote laws to ensure the triumph of industrialization in Western Europe, artists painted, wrote about, and composed music in response to the horrible conditions created by the Industrial Revolution. Only later did political leaders come to see what the artists had immediately perceived, and then only through a dark glass. Experience teaches us that___________.

Which of the following represents the most critical continuation of the passage?

  1. artistic vision perceives in advance of political practice

  2. artists are Utopian by nature while governmental leaders are practical

  3. throughout history political leaders have not been very responsive to the needs of their people

  4. the world would be a much better place to live if only artists would become kings

  5. history is the best judge of the progress of civilization


Correct Option: A
Explanation:

(1) The point of the passage is that artists see things as they really are, whereas politicians see things as they want them to be.

There is something irrational about our system of laws. The criminal law punishes a person more severely for having successfully committed a crime than it does a person who fails in his attempt to commit the same crime even though the same evil intention is present in both cases. But under the civil law a person who attempts to defraud his victim but is unsuccessful is not required to pay damages. Which of the following, if true, would most weaken the author's argument?

  1. Most persons who are imprisoned for crimes will commit another crime if they are ever released from prison.

  2. A person is morally culpable for his evil thoughts as well as for his evil deeds.

  3. There are more criminal laws on the books than there are civil laws on the books.

  4. A criminal trial is considerably more costly to the state than a civil trial.

  5. The goal of the criminal law is to punish the criminal, but the goal of the civil law is to compensate the victim.


Correct Option: E
Explanation:

(5) The point of the passage is that there is a seeming contradiction in our body of laws. Sometimes a person pays for his attempted misdeeds, and other times he does not pay for them. If there could be found a go5od reason for this difference, then the contradiction could be explained away. This is just what (5) does. It points out that the law treats the situations differently because it has different goals: Sometimes we drive fast because we are in a hurry; other times we drive slowly because we want to enjoy the scenery.

It is a well-documented fact that for all teenage couples who marry, the marriages of those who do not have children in the first year of their marriage survive more than twice as long as the marriages of those teenage couples in which the wife does give birth within the first 12 months of marriage. Therefore, many divorces could be avoided if teenagers who marry were encouraged to seek counselling on birth control as soon as possible after marriage.

The evidence regarding teenage marriages supports the author's conclusion only if

  1. a significant number of wives in such marriages were not pregnant at the time of marriage

  2. the children born during the first year of marriage to those divorcing couples lived with the teenage couple

  3. the child born into such a marriage did not die at birth

  4. society actually has an interest determining whether or not people should be divorced if there are not children involved

  5. encouraging people to stay married when they do not plan to have any children is a good idea


Correct Option: A
Explanation:

(1) The main point of the passage is that pregnancy and a child put strain on a young marriage and so, such marriages would have a higher survival rate without the strain of children. It would seem, then, that encouraging such couples not to have children would help them stay married; but that will be possible only if they have not already committed themselves, so to speak, to having a child. If the wife is already pregnant at the time of marriage, the commitment has already been made; so the advice is too late.

A parent must be constant and even-handed to settle imposition of burdens and punishments and the distribution of liberties and reward. In good times, a parent who too quickly bestows rewards creates an expectation of future rewards that he may be unable to fulfill during bad times. In bad times, a parent who waits too long to impose the punishment gives the impression that his response was forced, and the child may interpret this as ___________. Which of the following represents the most critical continuation of the passage?

  1. a signal from his parent that the parent is no longer interested in the child's welfare

  2. a sign of weakness in the parent that he can exploit

  3. indicating a willingness on the part of the parent to bargain away liberties in exchange for the child's assuming some new responsibilities

  4. an open invitation to retaliate

  5. a symbol of his becoming an adult


Correct Option: B
Explanation:

(2) The argument for consistency is that it avoids the danger that actions will be misinterpreted. If a parent is overly generous, a child will think the parent will always be generous, even when generosity is inappropriate. By the same token, if a parent does not draw the line until he is pushed to do so, the child will believe that he forced the parent's response. A parent, so goes the argument, should play it safe and leave himself a cushion.

The blanks in the following paragraph mark deletions from the text. For each question, select the phrase that most appropriately completes the text.Libertarians argue that laws making suicide a criminal act are both foolish and an unwarranted intrusion on individual conscience. With regard to the first, they point out that there is no penalty which the law can assess which inflicts greater injury than the crime itself. As for the second, they argue that it is no business of the state to prevent suicide, for whether it is right for a person to inflict fatal injury on himself or it is a matter between him and his God, one in which the state, by the terms of the Constitution, may not interfere. Such arguments, however, seem to me to be ill-conceived. In the first place, the libertarian makes the mistaken assumption that deference is the only goal of the law. I maintain that the laws we have proscribing suicide are (6). By making it a crime to take any life even one's own we make a public announcement of our shared conviction that each person is unique and valuable. In the second place, while it must be conceded that the doctrine of the separation of church and state is a useful one, it need not be admitted that suicide is a crime (7). And here we need not have recourse to the possibility that a potential suicide might, if given the opportunity, repent of his decision. Suicide inflicts a cost upon us all: the emotional cost on those close to the suicide; an economic cost in the form of a loss of production of a mature and trained member of the society which falls on us all; and a cost to humanity at large for the loss of a member of our community.

  1. drafted to make it more difficult to commit suicide

  2. passed by legislators in response to pressures by religious lobbying groups

  3. written in an effort to protect our democratic liberties, not undermine them

  4. important because they educate all about the value of human life

  5. outdated because they belong to a time when church and state were not separated


Correct Option: D
Explanation:

The author is attempting to argue that laws against suicide are legitimate. He argues against a simplistic libertarian position that says suicide hurts only the victim. The goal of the law, he argues, is not just to protect the victim from himself. A society passes such a law because it wants to underscore the importance of human life. Reading beyond the blank in the second paragraph makes clear the author's views on the value of human life.

The single greatest weakness of American parties is their inability to achieve cohesion in the legislature. Although there is some measure of party unity, it is not uncommon for the majority party to be unable to implement important legislation. The unity is strongest during election campaigns; after the primary elections, the losing candidates all promise their support to the party nominee. By the time the Congress convenes, the unity has dissipated. This phenomenon is attributable to the fragmented nature of party politics. The national committees are no more than feudal lords who receive nominal fealty from their vassals. A Congressman builds his own power on a local base. Consequently, a Congressman is likely to be responsive to local special interest groups. Evidence of this is seen in the differences in voting patterns between the upper and lower houses. In the Senate where terms are longer, there is more party unity. Which of the following, if true, would most strengthen the author's argument?

  1. On 30 key issues, 18 of the 67 majority party members in the Senate voted against the party leaders.

  2. On 30 key issues, 70 of the 305 majority party members in the House voted against the party leaders.

  3. On 30 key issues, over half of the members of the minority party in both houses voted with the majority party against the leaders of the minority party.

  4. Of 30 key legislative proposals introduced by the president, only eight passed both houses.

  5. Of 30 key legislative proposals introduced by a president whose party controlled a majority in both houses, only four passed both houses.


Correct Option: E
Explanation:

(5) The author is arguing that political parties in America are weak because there is no party unity. Because of this lack of unity, the party is unable to pass legislation. (5) would strengthen this contention. (5) provides an example of a government dominated by a single party (control of the presidency and both houses), yet the party is unable to pass its own legislation.

For each question, select the phrase that most appropriately completes the text.Libertarians argue that laws making suicide a criminal act are both foolish and an unwarranted intrusion on individual conscience.

  1. which does not necessarily lead to more serious crimes

  2. without victim

  3. as well as a sin

  4. which cannot be prevented

  5. without motive


Correct Option: B
Explanation:

(2) The author wants to make the point that suicide is not a victimless crime; it affects a great many people - even, he claims, some who were never personally acquainted with the suicide.

The main ingredient in this bottle of Dr. John's Milk of Magnesia is used by nine out of ten hospitals across the country as an antacid and laxative. If this advertising claim is true, which of the following statements must also be true? I. Nine out of ten hospitals across the country use Dr. John's Milk of Magnesia for some ailment. II. Only one out of ten hospitals in the country do not treat acid indigestion and constipation. III. Only one out of ten hospitals across the country do not recommend Dr. John's Milk of Magnesia for patients who need a milk of magnesia.

  1. I only

  2. II only

  3. I and III only

  4. I, II, and III

  5. None of the statements is necessarily true


Correct Option: E
Explanation:

The ad is a little deceptive. It tries to create the impression that if hospitals are using Dr. John's Milk of Magnesia, people will believe it is a good product. But what the ad actually says is that Dr. John uses the same ingredient that hospitals use (milk of magnesia is a simple suspension of magnesium hydroxide in water). The ad is something like an ad for John's Vinegar which claims it has acetic acid, which is vinegar. I falls into the trap of the ad and is therefore wrong. II is not inferable since there may be treatments other than milk of magnesia for these disorders. Finally, since I is incorrect, III must certainly also be incorrect. Even if I had been true, III might still be questionable since use and recommendation are not identical.

I recently read a book by an author who insists that everything man does is economically motivated. Leaders launch wars of conquest in order to capture the wealth of other nations. Scientists do research in order to receive grants or find marketable processes. Students go to college to get better jobs. He even maintains that people go to museums to become better informed on the off-chance that some day they will be able to turn that knowledge to their advantage. So persuaded was I by the author's evidence that, applying his theory on my own, I was able to conclude that he had written the book __________. Which of the following provides the most critical completion of the above paragraph?

  1. as a labor of love

  2. in order to make money

  3. as a means of reforming the world by calling man's attention to his greed

  4. as an exercise in scientific research in response to a creative urge to be a novelist

  5. in response to a creative urge to be a novelist


Correct Option: C
Explanation:

(3) The paragraph started with the fact that everything done is economically motivated. Option (2) seems to be close , as it conforms to the fact stated in the opening lines of the passage. But when we see (3) and (2) and carefully read the paragraph we will see that the reader was able to conclude that the book was aimed to draw attention to man's avarice. So we conclude that (3) is a better fit than (2).

I. Everyone who has not read the report either has no opinion in the matter or holds a wrong opinion about it. II. Everyone who holds no opinion in the matter has not read the report.Which of the following best describes the relationship between the two above propositions?

  1. If II is true, I may be either false or true.

  2. If II is true, I must also be true.

  3. If II is true, I is likely to be true.

  4. If I is true, II must also be true.

  5. If I is false, II must also be false.


Correct Option: A
Explanation:

(1) The form of the argument can be represented using letters as:

I.          All R are either O or W (All non-Readers are non-Opinion holders or Wrong.)
II.         All O are R. If II is true, I might be either false or true, since it is possible that there are some who have not read the report who hold right opinions. That is, even if II is true and all O are R, that does not tell us anything about all the R's, only about all the O's. The rest of the R's might be W's (wrong-opinion holders) or something else altogether (right-opinion holders).

If the batteries in my electric razor are dead, the razor will not function. My razor is not functioning. Therefore, the batteries must be dead. Which of the following arguments is most similar to that presented above?

  1. If Elroy attends the meeting, Ms. Barker will be elected club president. Ms. Barker was not elected club president; therefore, Elroy did not attend the meeting.

  2. All evidence is admissible unless it is tainted. This evidence is inadmissible. Therefore, it is tainted.

  3. If John committed the crime, his fingerprints will be found at the scene. John's fingerprints were found at the scene; therefore, John committed the crime.

  4. Grant is my uncle. Sophie is Grant's niece. Therefore, Sophie is my sister.


Correct Option: C
Explanation:

(3) The stem argument has the form: “lf P, then Q. Q, therefore, P.” The argument is invalid. There may be other reasons that the razor is not functioning, e.g., the switch is not on, it is broken, etc. (3) has this form also. John's fingerprints might have been found at the scene, yet he may not have committed the crime.

The single greatest weakness of American parties is their inability to achieve cohesion in the legislature. Although there is some measure of party unity, it is not uncommon for the majority party to be unable to implement important legislation. The unity is strongest during election campaigns; after the primary elections, the losing candidates all promise their support to the party nominee. By the time the Congress convenes, the unity has dissipated. This phenomenon is attributable to the fragmented nature of party politics. The national committees are no more than feudal lords who receive nominal fealty from their vassals. A Congressman builds his own power on a local base. Consequently, a Congressman is likely to be responsive to local special interest groups. Evidence of this is seen in the differences in voting patterns between the upper and lower houses. In the Senate where terms are longer, there is more party unity. Which of the following, if true, would most weaken the author's argument?

  1. Congressmen receive funds from the national party committee.

  2. Senators vote against the party leaders only two-thirds as often as members of the House.

  3. The primary duty of an officeholder is to be responsive to his local constituency rather than party leaders.

  4. There is more unity among minority party members than among majority party members.

  5. Much legislation is passed each session despite party disunity.


Correct Option: C
Explanation:

(3) Here we are looking for the argument that will undermine the position taken by the paragraph. Remember that the ultimate conclusion of the paragraph is that this disunity is a weakness arid that this prevents legislation from being passed. One very good way of attacking this argument is to attack the value judgment on which the conclusion is based: Is it good to pass the legislation? The author assumes that it would be better to pass the legislation. We could argue, as in (3), that members of the Congress should not pass legislation simply because it is proposed by the party leadership. Rather, the members should represent the views of their constituents. Then, if the legislation fails, it must be the people who did not want it. In that case, it is better not to pass the legislation.

The existence of our state's inefficient and wasteful automobile accident liability system can be easily explained. As long as most of our legislators are lawyers, the system will never be reformed, because litigation creates more work for lawyers. The argument above rests on the assumption that

  1. given the opportunity, most lawyers would want to be members of the state legislature

  2. legislation to reform the state's automobile accident liability system could be introduced by a legislator who is not a lawyer

  3. state laws set minimum fees that attorneys are permitted to charge in cases arising from automobile accidents

  4. the state's automobile accident liability system encourages litigation

  5. state laws governing the ownership and operation of motor vehicles encourage unsafe driving practices


Correct Option: D
Explanation:

(4) The argument above has the structure: Litigation creates work for lawyers; therefore, these laws will not be reformed. The speaker apparently believes, though he does not say so explicitly, that the existing system of laws encourages litigation. Thus, (4) highlights a suppressed premise of the argument.

The existence of our state's inefficient and wasteful automobile accident liability system can be easily explained. As long as most of our legislators are lawyers, the system will never be reformed, because litigation creates more work for lawyers. Which of the following, if true, would most weaken the argument above?

  1. Most judges in the state are members of the legal profession as well.

  2. Few of the state's legislators are among the relatively small percentage of lawyers who handle automobile accident cases.

  3. Under the customary fee arrangement, a lawyer receives one-third of any monetary award made to a client.

  4. The state legislature allocates funds to pay for defense attorneys who represent indigent clients.

  5. Any reform legislation could be vetoed by the governor of the state, who is also an attorney.


Correct Option: B
Explanation:

(2) The initial argument tries to provide an explanation for a certain situation: The lawyers in the legislatures refuse to reform the law because reform would reduce the income of lawyers. In other words, the initial argument suggests that the lawyers in the legislature act out of self-interest. The argument implicitly assumes that the lawyers in the legislature derive financial benefit from the existing laws. (2) attacks this hidden assumption of the argument.
