1.People who have specialized knowledge about a
scientific or technical issue are systematically
excluded from juries for trials where the issue is
relevant. Thus, trial by jury is not a fair means of
settling disputes involving such issues.
Which one of the following, if true, most seriously
weakens the argument?
Weaken Question Problem Set NO.9
(A) The more complicated the issue being litigated,
the less likely it is that a juror without
specialized knowledge of the field involved
will be able to comprehend the testimony
being given.
(B) The more a juror knows about a particular
scientific or technical issue involved in a
trial, the more likely it is that the juror will be
prejudiced in favor of one of the litigating
parties before the trial begins.
(C) Appointing an impartial arbitrator is not a fair
means of settling disputes involving
scientific or technical issues, because
arbitrators tend to favor settlements in which
both parties compromise on the issues.
(D) Experts who give testimony on scientific or
technical issues tend to hedge their
conclusions by discussing the possibility of
error.
(E) Expert witnesses in specialized fields often
command fees that are so high that many
people involved in litigation cannot afford
their services.

To reduce the danger to life and property posed by major earthquakes, scientists have been investigating several techniques for giving advance warning of dangerous earthquakes. Since catfish swim erratically before earthquakes, some investigators have proposed monitoring catfish to predict dangerous earthquakes.
Which of the following, if true, most seriously undermines the usefulness of the proposal?
(A) In Japan, which is subject to frequent earthquakes, the behavior of catfish has long been associated with earthquakes.
(B) Mechanical methods for detecting earthquakes have not proved effective.
(C) Tremors lead to the release of hydrogen sulfide gas into water, thereby causing various fish and shellfish to behave erratically.
(D) Careful construction can reduce the dangers posed by earthquakes.
(E) Even very slight, fleeting tremors cause catfish to swim erratically.

30.
A city plans to attract new citizens with new housing and new facilities such as parks, recreation centers, and libraries. One component of the city's plan is to require that developers seeking permission to build this new housing provide these additional facilities at no cost to the city.
Which of the following, if true, would point to a possible flaw in the city's plan?
(A) Developers would pass along their costs to the buyer, thereby raising the cost of housing units beyond the ability of likely purchasers to afford them.
(B) Light, nonpolluting industries have located in the area, offering more jobs and better-paying jobs than do the more-established industries in the area.
(C) Other towns and cities nearby have yet to embark on any comparable plans to attract new citizens.
(D) Most developers see the extra expense of providing municipal facilities as simply one of the many costs of doing business.
(E) Studies show that purchasers of new houses, especially first-time buyers, rank recreational resources as an important factor in deciding to buy a particular house.

31.
Manufacturers issue cents-off coupons to get consumers to try their brand of product with the hope that the consumers who try their brand will switch their brand loyalty. So in the initial marketing of their new brand X, Hartman Industries should issue cents-off coupons, thereby attracting a large segment of potential consumers as loyal customers.
Which of the following, if true, casts the most serious doubt on the likelihood that the marketing strategy recommended above will have the result that is claimed?
(A) Many consumers are unlikely to try new brands of products unless offered an inducement to do so.
(B) The consumers whose purchases are strongly influenced by cents-off coupons tend not to become loyal customers of any particular brand.
(C) Many grocery stores attract customers by doubling the face value of manufacturer's coupons.
(D) Typically less than one-third of the coupons issued by a manufacturer are redeemed by consumers.
(E) A marketing campaign that uses cents-off coupons is most effective when combined with a television advertising campaign.

32.
State spokesperson: Many businesspeople who have not been to our state believe that we have an inadequate road system. Those people are mistaken, as is obvious from the fact that in each of the past six years, our state has spent more money per mile on road improvements than any other state.
Which of the following, if true, most seriously undermines the reasoning in the spokesperson's argument?
(A) In the spokesperson's state, spending on road improvements has been increasing more slowly over the past six years than it has in several other states.
(B) Adequacy of a state's road system is generally less important to a businessperson considering doing business there than is the availability of qualified employees.
(C) Over the past six years, numerous businesses have left the spokesperson's state, but about as many businesses have moved into the state.
(D) In general, the number of miles of road in a state's road system depends on both the area and the population of the state.
(E) Only states with seriously inadequate road systems need to spend large amounts of money on road improvements.

逻辑链答案： E A B E
精炼解析：
Question #3. December 2003 LSAT, Section #1, #20. The correct answer choice is (B)
The first sentence is a premise, and the second sentence is the conclusion of this argument. To attack this
conclusion, look for an answer choice that shows that the exclusion of knowledgeable individuals from
scientific or technical issue trials is a fair way of proceeding in these trials.
Answer choice (A): This is an Opposite answer that strengthens the conclusion. If specialized knowledge
of these issues makes it more likely that the juror can comprehend the testimony being given, then these
individuals should not be excluded from juries, and their exclusion makes trial by jury an unfair means of
resolving a dispute.
Answer choice (B): This is the correct answer. If the specialized knowledge is likely to produce a
prejudice in a juror, then by all means they should be excluded from the jury. Thus, instead of trial by jury
being an unfair means, it is made more fair by the exclusion of these individuals. The answer is a tricky
one because most people initially think the answer agrees with the argument. It agrees with the principle of
the premise, but not with the conclusion drawn from that premise.
Answer choice (C): This answer simply notes that arbitrators are not a fair means of settling scientific or
technical issue debates. This has no impact on the fairness of jury trials involving these same issues.
Answer choice (D): This answer is about the experts testifying at scientific or technical issue trials. This
information does not attack the claim that jury trials are unfair because of the exclusion of jurors with
knowledge of these issues.
Answer choice (E): This answer can be eliminated by reasoning similar to that used to eliminate answer
choice (D).
