People who accuse the postal service of incompetence and inefficiency while complaining of the proposed five-cent increase in postal rates do not know a bargain when they see one. Few experiences are more enjoyable than reading a personal letter from a friend. Viewed in this way, postal service is so underpriced that a five-cent increase is unworthy of serious debate. The reasoning in the argument is flawed because the argument (A) suggests that the postal service is both competent and efficient, but does not establish how competence and efficiency should be measured (B) claims that the proposed increase is insignificant but does not say at what level the increase would be worthy of serious debate (C) confuses the value of the object delivered with the value of delivering that object (D) appeals to an outside authority for support of a premise that should be established by argument (E) fails to establish whether or not the critics of the postal service are employees of the postal service

Short Answer

Expert verified
(C) confuses the value of the object delivered with the value of delivering that object.

Step by step solution

01

Understanding the Argument

The argument claims that those who complain about the postal service's proposed rate increase do not appreciate a good deal, suggesting that postal service is so valuable that the increase is trivial.
02

Identifying the Argument's Flaw

To determine the flaw, assess where the argument's reasoning has gaps. The error arises when the argument equates the enjoyment of a received letter (the content) with the service itself (delivery), suggesting the value of delivery is understated solely due to the enjoyment of the letter.
03

Evaluating the Options

Review each option to find the one that best describes the argument's flawed reasoning. Option C points out the confusion between the value of the content delivered (the enjoyment from reading a letter) and the value of the delivery service itself, which the argument fails to clearly distinguish.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Argument Analysis
Argument analysis is a critical skill, especially when tackling exercises like those found in LSAT Logical Reasoning sections. The essence of argument analysis is to break down the argument into clear components, which include the premises and the conclusion. The goal is to understand the basic structure and whether the conclusion indeed follows logically from the premises.
In the original exercise, the argument suggests that a five-cent increase in postal rates is trivial because receiving personal mail is a profound experience. While analyzing this argument, it’s important to identify the claim (postal service is a bargain even with a rate increase) and the underlying assumption (the value of the service equals the pleasure of the mail). This implies a logical leap, where the enjoyment of reading a letter is confounded with the value of the delivery service itself.
To effectively analyze any argument, look for these components:
  • Identify the main conclusion – this is what the argument is trying to convince you of.
  • Pinpoint the evidence provided – these are the premises or reasons given to support the conclusion.
  • Detect any assumptions – these are unstated premises that link the evidence to the conclusion.
Recognizing these elements is crucial in discerning the logical soundness of an argument.
Logical Fallacies
Logical fallacies often hide in the gaps between evidence and conclusion, making otherwise convincing arguments flawed. A logical fallacy occurs when reasoning breaks down or is based on faulty logic. Understanding different types of logical fallacies can help you spot weaknesses in arguments.
In the exercise, the argument commits a type of logical fallacy known as equivocation. This fallacy occurs when a word or phrase is used ambiguously in the argument. Here, the argument mixes the value of the postal service with the personal enjoyment of a letter received. It confuses the qualitative feeling of receiving a letter with the monetary worth of sending it.
Here are some common logical fallacies you might encounter:
  • Ad Hominem – attacking the person instead of the argument.
  • Straw Man – misrepresenting an argument to make it easier to attack.
  • False Dilemma – presenting two options as the only possible choices.
  • Appeal to Emotion – manipulating emotions rather than using valid reasoning.
Recognizing these fallacies requires practice but ultimately strengthens critical reasoning skills.
Critical Reasoning
Critical reasoning goes beyond mere comprehension; it involves analyzing, evaluating, and constructing arguments. It is indispensable for LSAT prep as it enables you to dissect arguments, identify unstated assumptions, and evaluate the strength of evidence presented.
In the context of the exercise provided, critical reasoning allows you to question the connection between the pleasure derived from a letter and its delivery service. Is the argument really showing you why a five-cent increase is trivial? Or is it subtly relying on the emotional weight of personal communication to overshadow logical evaluation of the service cost?
To engage in critical reasoning:
  • Question the relevance of each premise – how does it specifically support the conclusion?
  • Look for gaps in logic – are there assumptions made that haven't been justified?
  • Evaluate the sufficiency of evidence – does the argument rely heavily on subjective matters rather than objective data?
These skills will not only aid in answering LSAT questions but will enhance overall decision-making and problem-solving abilities.
LSAT Prep
Preparing for the LSAT requires mastering various types of logical reasoning patterns and developing the skill to swiftly identify and evaluate elements of arguments. The LSAT Logical Reasoning section tests your ability to apply argument analysis, recognize logical fallacies, and utilize critical reasoning under time constraints.
For effective LSAT prep, it is essential to focus on a few key strategies:
  • Practice regularly with timed drills - to become efficient and accurate under test conditions.
  • Analyze past logical reasoning questions - pay attention to commonly used fallacies and argument structures.
  • Review incorrect answers - to understand mistakes and learn from them.
Remember, the goal of LSAT prep is not just immediate familiarity but also building a deep understanding of logical analysis that will serve you well in both the exam and future legal studies.
Test Preparation
General test preparation involves more than mastering content; it requires strategizing and creating a study schedule that suits your learning style and goals. For anyone tackling the LSAT, integrating logical reasoning practice with overall test preparation is essential.
Here’s how to effectively prepare for tests, with a focus on logical reasoning:
  • Create a study plan – allocate time for consistent and varied practice, including full-length practice tests.
  • Understand the test format – familiarizing yourself with the structure and timing can reduce stress on test day.
  • Relaxation techniques – such as mindfulness can help maintain focus during preparation and the actual test.
  • Seek feedback – from practice tests or study groups to uncover areas needing improvement.
Comprehensive test preparation doesn’t just aim for performance in one area; it ensures that you are mentally, strategically, and emotionally ready to tackle the test as a whole.

Crimes in which handguns are used are more likely than other crimes to result in fatalities. However, the majority of crimes in which handguns are used do not result in fatalities. Therefore, there is no need to enact laws that address crimes involving handguns as distinct from other crimes. The pattern of flawed reasoning displayed in the argument above most closely resembles that in which one of the following? (A) Overweight people are at higher risk of developing heart disease than other people. However, more than half of all overweight people never develop heart disease. Hence it is unnecessary for physicians to be more careful to emphasize the danger of heart disease to their overweight patients than to their other patients. (B) Many people swim daily in order to stay physically fit. Yet people who swim daily increase their risk of developing ear infections. Hence people who want to remain in good health are better off not following fitness programs that include swimming daily. (C) Most physicians recommend a balanced diet for those who want to remain in good health. Yet many people find that nontraditional dietary regimens such as extended fasting do their health no serious harm. Therefore, there is no need for everyone to avoid nontraditional dietary regimens. (D) Foods rich in cholesterol and fat pose a serious health threat to most people. However, many people are reluctant to give up eating foods that they greatly enjoy. Therefore, people who refuse to give up rich foods need to spend more time exercising than do other people. (E) Many serious health problems are the result of dietary disorders. Yet these disorders are often brought about by psychological factors. Hence people suffering from serious health problems should undergo psychological evaluation.

A local group had planned a parade for tomorrow, but city hall has not yet acted on its application for a permit. The group had applied for the permit well in advance, had made sure their application satisfied all the requirements, and was clearly entitled to a permit. Although the law prohibits parades without a permit, the group plans to proceed with its parade. The group's leader defended its decision by appealing to the principle that citizens need not refrain from actions that fail to comply with the law if they have made a good-faith effort to comply but are prevented from doing so by government inaction. Which one of the following actions would be justified by the principle to which the leader of the group appealed in defending the decision to proceed? (A) A chemical-processing company commissioned an environmental impact report on its plant. The report described foul odors emanating from the plant but found no hazardous wastes being produced. Consequently, the plant did not alter its processing practices. (B) A city resident applied for rezoning of her property so that she could build a bowling alley in a residential community. She based her application on the need for recreational facilities in the community. Her application was turned down by the zoning board, so she decided to forego construction. (C) The law requires that no car be operated without a certain amount of insurance coverage. But since the authorities have been unable to design an effective procedure for prosecuting owners of cars that are driven without insurance, many car owners are allowing their insurance to lapse. (D) A real-estate developer obtained a permit to demolish a historic apartment building that had not yet been declared a governmentally protected historic landmark. Despite the protests of citizens' groups, the developer then demolished the building. (E) A physician who had been trained in one country applied for a license to practice medicine in another country. Although he knew he met all the qualifications for this license, he had not yet received it one year after he applied for it. He began to practice medicine without the license in the second country despite the law's requirement for a license.

Waste management companies, which collect waste for disposal in landfills and incineration plants, report that disposable plastics make up an ever- increasing percentage of the waste they handle. It is clear that attempts to decrease the amount of plastic that people throw away in the garbage are failing. Which one of the following, if true, most seriously weakens the argument? (A) Because plastics create harmful pollutants when burned, an increasing percentage of the plastics handled by waste management companies are being disposed of in landfills. (B) Although many plastics are recyclable, most of the plastics disposed of by waste management companies are not. (C) People are more likely to save and reuse plastic containers than containers made of heavier materials like glass or metal. (D) An increasing proportion of the paper, glass, and metal cans that waste management companies used to handle is now being recycled. (E) While the percentage of products using plastic packaging is increasing, the total amount of plastic being manufactured has remained unchanged.

Politician: From the time our party took office almost four years ago the number of people unemployed city-wide increased by less than 20 percent. The opposition party controlled city government during the four preceding years, and the number of unemployed city residents rose by over 20 percent. Thus, due to our leadership, fewer people now find themselves among the ranks of the unemployed, whatever the opposition may claim. The reasoning in the politician's argument is most vulnerable to the criticism that (A) the claims made by the opposition are simply dismissed without being specified (B) no evidence has been offered to show that any decline in unemployment over the past four years was uniform throughout all areas of the city (C) the issue of how much unemployment in the city is affected by seasonal fluctuations is ignored (D) the evidence cited in support of the conclusion actually provides more support for the denial of the conclusion (E) the possibility has not been addressed that any increase in the number of people employed is due to programs supported by the opposition party

English and the Austronesian language Mbarbaram both use the word "dog" for canines. These two languages are unrelated, and since speakers of the two languages only came in contact with one another long after the word "dog" was first used in this way in either language, neither language could have borrowed the word from the other. Thus this case shows that sometimes when languages share words that are similar in sound and meaning the similarity is due neither to language relatedness nor to borrowing. The argument requires that which one of the following be assumed? (A) English and Mbarbaram share no words other than "dog." (B) Several languages besides English and Mbarbaram use "dog" as the word for canines. (C) Usually when two languages share a word, those languages are related to each other. (D) There is no third language from which both English and Mbarbaram borrowed the word "dog." (E) If two unrelated languages share a word, speakers of those two languages must have come in contact with one another at some time.
