OA is C. This is a GMATprep qn. Does anyone know why C? I am baffled..

At present, the Hollywood restaurant has only standard height tables. However, many customers come to watch celebrities who frequent Hollywood & they prefer tall tables in stools because such seating would afford better view of the celebrities. However, dinners seated on stools typically do not stay as long as diners seated on standard height tables. Therefore, if the Hollywood restaurant replaced some of its seating with higher tables and stools, its profits would increase. The statement is vulnerable to criticism in that it gives reason to believe that it is likely that: (a) Some celebrities come to Hollywood restaurant to be seen and so might choose to sit at tall tables if they are available (b) The price of meals ordered by celebrities dining at Hollywood restaurant compensates for longer time, if any, that they spend lingering over their meals © A customer of the Hollywood restaurant who would choose to sit at a tall table would be an exception to the generatlisation about lingering (d) A restaurant's customer who spends less time at their meal typically orders less expensive meals than those who remain at their meals longer (e) With enough tall tables to accommodate all Hollywood restaurant's customers interested in such seating, there would be no view except of other tall tables

Sorry for delay. OA is C. Why is D incorrect?

Pple ought to take into account a discipline's blemished origins when assessing scientific value of discipline. Take, for example, chemistry. It must be considered that many of its landmark results were obtained by alchemists- a gp whose superstitions and appeals to magic dominated the early part of chemical theory. Reasoning above is most susceptible to criticism because author: (a) fails to establish that disciplines with unblemished origins are scientifically valuable (b) fails to consider how chemistry's current theories and practices differ from those of the alchemists mentioned © uses example to contradict principle under consideration (d) does not prove that most disciplines that are not scientifically valuable have origins that are in some way suspect (e) uses word "discipline" in two different senses. This is an LSAT qn.

OA is E

OA is D. This qn was from LSAT Jun 2004, Section 1, qn 20 of critical reasoning. Does anyone know why OA is D?

Antinuclear activist: The closing of the nuclear power plant is a victory for the antinuclear cause. It also represents a belated acknowledgment by the power industry that they cannot operate such plants safely. Nuclear power plant manager: It represents no such thing. The availability of cheap power from nonnuclear sources, together with the cost of mandated safety inspections and safety repairs, made continued operation uneconomic. Thus it was not safety considerations but economic considerations that dictated the plant’s closing. Which one of the following, if true, most strongly supports the activist’s claim of victory? (A) The plant had reached the age at which its operating license expired. (B) The mandate for inspections and repairs mentioned by the manager was recently enacted as a result of pressure from antinuclear groups. © The plant would not have closed if cheap power from nonnuclear sources had not been available. (D) Per unit of electricity produced, the plant had the highest operating costs of any nuclear power plant. (E) The plant that closed had been able to provide backup power to an electrical network when parts of the network became overloaded.

Interviewer: A certain company released a model of computer whose microprocessor design was flawed, making that computer liable to process information incorrectly. How did this happen? Industry spokesperson: Given the huge number of circuits in the microprocessor of any modern computer, not every circuit can be manually checked before a computer model that contains the microprocessor is released. Interviewer: Then what guarantee do we have that new microprocessors will not be similarly flawed? Industry spokesperson: There is no chance of further microprocessor design flaws, since all microprocessors are now entirely computer designed. The industry spokesperson’s argument is most vulnerable to criticism on the grounds that it (A) presumes, without providing justification, that the microprocessor quality-control procedures of the company mentioned are not representative of those followed throughout the industry (B) ignores the possibility that a microprocessor can have a flaw other than a design flaw © overlooks the possibility that a new computer model is liable to malfunction for reasons other than a microprocessor flaw (D) treats a single instance of a microprocessor design flaw as evidence that there will be many such flaws (E) takes for granted, despite evidence to the contrary, that some computers are not liable to error

In a highly publicized kidnapping case in Ontario, the judge barred all media and spectators from the courtroom. Her decision was based on the judgment that the public interest would not be served by allowing spectators. A local citizen argued, "They pleaded with the public to help find the victim; they pleaded with the public to provide tips; they aroused the public interest, then they claimed that allowing us to attend would not serve the public interest. These actions are inconsistent." The reasoning in the local citizen’s argument is flawed because this argument (A) generalizes from an atypical case (B) trades on an ambiguity with respect to the term "public interest" © overlooks the fact that the judge might not be the one who made the plea to the public for help (D) attempts to support its conclusion by making sensationalistic appeals (E) presumes that the public’s right to know is obviously more important than the defendant’s right to a fair trial ago.

If one of the effects of a genetic mutation makes a substantial contribution to the survival of the species, then, and only then, will that mutation be favored in natural selection. This process is subject to one proviso, namely that the traits that were not favored, yet were carried along by a trait that was favored, must not be so negative as to annul the benefits of having the new, favored trait. If the statements above are true, each of the following could be true EXCEPT: (A) A species possesses a trait whose effects are all neutral for the survival of that species. (B) All the effects of some genetic mutations contribute substantially to the survival of a species. © A species possesses a trait that reduces the species’ survival potential. (D) A genetic mutation that carries along several negative traits is favored in natural selection. (E) A genetic mutation whose effects are all neutral to a species is favored in natural selection.

Resident: Residents of this locale should not consider their loss of farming as a way of life to be a tragedy. When this area was a rural area it was economically depressed, but it is now a growing bastion of high-tech industry with high-wage jobs, and supports over 20 times the number of jobs it did then. Which one of the following, if true, does the most to justify the conclusion of the resident’s argument? (A) Farming is becoming increasingly efficient, with the result that fewer farms are required to produce the same amount of food. (B) The development of high-tech industry is more valuable to national security than is farming. © Residents of this locale do not value a rural way of life more than they value economic prosperity. (D) Many residents of this locale have annual incomes that are twice what they were when the locale was primarily agricultural. (E) The loss of a family farm is often perceived as tragic even when no financial hardship results.

Environmentalist: Many people prefer to live in regions of natural beauty. Such regions often experience an influx of new residents, and a growing population encourages businesses to relocate to those regions. Thus, governmentally mandated environmental protection in regions of natural beauty can help those regions’ economies overall, even if such protection harms some older local industries. Which one of the following is an assumption on which the environmentalist’s argument depends? (A) Regions of natural beauty typically are beautiful enough to attract new residents only until governmentally mandated environmental protection that damages local industries is imposed. (B) The economies of most regions of natural beauty are not based primarily on local industries that would be harmed by governmentally mandated environmental protection. © If governmentally mandated environmental protection helps a region’s economy, it does so primarily by encouraging people to move into that region. (D) Voluntary environmental protection usually does not help a region’s economy to the degree that governmentally mandated protection does. (E) A factor harmful to some older local industries in a region need not discourage other businesses from relocating to that region.

No small countries and no countries in the southern hemisphere have permanent seats on the United Nations Security Council. Each of the five countries with a permanent seat on the Security Council is in favor of increased international peacekeeping efforts and a greater role for the United Nations in moderating regional disputes. However, some countries that are in favor of increased international peacekeeping efforts are firmly against increased spending on refugees by the United Nations. If the statements above are true, which one of the following must also be true? (A) Some small countries do not want the United Nations to increase its spending on refugees. (B) Some countries in the southern hemisphere are not in favor of increased international peacekeeping efforts. © Some countries that have permanent seats on the United Nations Security Council are against increased spending on refugees by the United Nations. (D) Some small countries are in favor of a greater role for the United Nations in moderating regional disputes. (E) Some countries that are in favor of a greater role for the United Nations in moderating regional disputes are not located in the southern hemisphere.

Social critic: One of the most important ways in which a society socializes children is by making them feel ashamed of their immoral behavior. But in many people this shame results in deep feelings of guilt and self-loathing that can be a severe hardship. Thus, moral socialization has had a net effect of increasing the total amount of suffering. The social critic’s argument is most vulnerable to criticism on the grounds that it (A) overlooks the possibility that the purported source of a problem could be modified to avoid that problem without being eliminated altogether (B) fails to address adequately the possibility that one phenomenon may causally contribute to the occurrence of another, even though the two phenomena do not always occur together © presumes, without providing justification, that a phenomenon that supposedly increases the total amount of suffering in a society should therefore be changed or eliminated, regardless of its beneficial consequences (D) takes for granted that a behavior that sometimes leads to a certain phenomenon cannot also significantly reduce the overall occurrence of that phenomenon (E) presumes, without providing justification, that if many people have a negative psychological reaction to a phenomenon, then no one can have a positive reaction to that phenomenon
