Between 1971 and 1975, the government office that monitors drug companies issued an average of 60 citations a year for serious violations of drug- promotion laws. Between 1976 and 1980, the annual average for issuance of such citations was only 5 . This decrease indicates that the government office was, on average, considerably more lax in enforcing drug-promotion laws between 1976 and 1980 than it was between 1971 and 1975. The argument assumes which one of the following? (A) The decrease in the number of citations was not caused by a decrease in drug companies' violations of drug-promotion laws. (B) A change in enforcement of drug-promotion laws did not apply to minor violations. (C) The enforcement of drug-promotion laws changed in response to political pressure. (D) The government office should not issue more than an average of 5 citations a year to drug companies for serious violations of drug-promotion laws. (E) Before 1971 the government office issued more than 60 citations a year to drug companies for serious violations of drug-promotion laws.

Short Answer

Expert verified
The argument assumes (A).

Step by step solution

01

Understand the Argument

The argument suggests that a decrease in citations indicates a more lax enforcement of drug-promotion laws from 1976 to 1980 compared with 1971 to 1975.
02

Analyze the Assumption

For the argument to hold, it must assume that the decrease in citations is not due to a reduction in the number of actual violations.
03

Evaluate Option A

Option A states that the decrease in the number of citations was not caused by a decrease in violations. If true, this supports the idea that enforcement was laxer.
04

Evaluate Option B

Option B focuses on minor violations, but the argument concerns serious violations. Therefore, it is not directly relevant.
05

Evaluate Option C

Option C suggests political pressure influenced enforcement, but the argument does not address why enforcement changed, only that it was laxer.
06

Evaluate Option D

Option D implies a normative statement about the number of citations that should be issued, which does not relate to the assumption of why fewer citations were issued.
07

Evaluate Option E

Option E discusses the number of citations before 1971, which is irrelevant to the argument comparing 1971-1975 to 1976-1980.
08

Select the Correct Assumption

Option A is the assumption underlying the argument; it indicates that fewer citations must imply laxer enforcement rather than fewer violations.

Key Concepts

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

Assumption Identification
When analyzing arguments in logical reasoning, one of the most crucial skills to develop is assumption identification. Assumptions are unstated premises that must be true for an argument to hold. These are the skeletons holding the structure of the argument in place. Understanding these hidden elements is particularly important on exams like the LSAT, where argument evaluation is a core component.

In the exercise about the decrease in citations, the argument assumes that the drop in numbers did not result from fewer violations. This means that the author believes no other explanations account for the decrease except a lax in enforcement. If this assumption is incorrect, the argument falls apart. To identify assumptions, ask yourself what must be true for the conclusion to make sense. This practice broadens your understanding and prepares you for various logical scenarios. It also hones your critical thinking abilities, enabling you to dissect arguments and pinpoint their weaknesses.
Logical Analysis
Logical analysis involves dissecting an argument into its fundamental parts to evaluate its validity and soundness. This skill helps to identify the reasoning pattern and evaluate how conclusions are drawn from premises. When an argument is presented, it is essential to look at the evidence supporting the conclusion and ask if it logically connects to the conclusion given.

For the exercise on citation statistics, the logical analysis involves examining the correlation between the number of citations and the enforcement of drug-promotion laws. What assumptions are being made about this correlation? Is it valid to say that fewer citations mean more lax enforcement without further evidence? Logical analysis aids in these evaluations, ensuring that arguments are not accepted at face value but are critically examined for logical consistency.
  • Identify the premises and conclusion.
  • Determine whether the premises logically support the conclusion.
  • Look for any logical fallacies or gaps in reasoning.
Argument Evaluation
Argument evaluation is an extension of logical analysis, focusing not just on dissecting an argument but assessing its overall strength and relevance. In this step, we scrutinize the supporting evidence, the logical flow, and the underlying assumptions to decide whether the argument is convincing.

For the exercise in question, evaluating the argument requires understanding why option A is the correct choice. Here, we ask: Does the evidence provided support the conclusion that oversight was more lax? What other factors might be at play, like improvements in pharmaceutical compliance or changes in citation criteria? Evaluating an argument involves looking beyond the surface to see if alternative explanations or evidence compromises the argument's strength. It's about being skeptical in a constructive way to ensure that the argument is watertight.
Critical Thinking
Critical thinking is the art of systematic evaluation to form a judgment. This involves stepping back and viewing an argument from multiple angles, considering not just the given information but also what is left unsaid. On exams like the LSAT, this skill is vital for navigating not just the logical reasoning section but the entire test.

In our exercise, critical thinking requires us to question the given decrease in citations. Is it fair to attribute this purely to laxness without evidence? Could there be other interpretations? Such as changes in industry standards or shifts in policy focus? Critical thinking pushes you to think deeper than surface-level analysis, encouraging you to challenge assumptions, evaluate evidence rigorously, and construct logical, well-founded conclusions.
  • Ask reflective questions rather than taking information as given.
  • Compare different viewpoints to assess their validity.
  • Look for hidden biases or assumptions that might skew interpretation.

Harry Trevalga: You and your publication have unfairly discriminated against my poems. I have submitted thirty poems in the last two years and you have not published any of them! It is all because I won the Fenner Poetry Award two years ago and your poetry editor thought she deserved it. Publisher: Ridiculous! Our editorial policy and practice is perfectly fair, since our poetry editor judges all submissions for publication without ever seeing the names of the poets, and hence cannot possibly have known who wrote your poems. The publisher makes which one of the following assumptions in replying to Trevalga's charges of unfair discrimination? (A) The poetry editor does not bear a grudge against Harry Trevalga for his winning the Fenner Poetry Award. (B) It is not unusual for poets to contribute many poems to the publisher's publication without ever having any accepted for publication. (C) The poetry editor cannot recognize the poems submitted by Harry Trevalga as his unless Trevalga's name is attached to them. (D) The poetry editor's decisions on which poems to publish are not based strictly on judgments of intrinsic merit. (E) Harry Trevalga submitted his poems to the publisher's publication under his pen name.

Advertisement: HomeGlo Paints, Inc., has won the prestigious Golden Paintbrush Award given to the one paint manufacturer in the country that has increased the environmental safety of its product most over the past three years-for HomeGlo Exterior Enamel. The Golden Paintbrush is awarded only on the basis of thorough tests by independent testing laboratories. So when you choose HomeGlo Exterior Enamel, you will know that you have chosen the most environmentally safe brand of paint manufactured in this country today. The flawed reasoning in the advertisement most closely parallels that in which one of the following? (A) The ZXC audio system received the overall top ranking for looks, performance, durability, and value in Listeners' Report magazine's ratings of currently produced systems. Therefore, the ZXC must have better sound quality than any other currently produced sound system. (B) Moming Sunshine breakfast cereal contains, ounce for ounce, more of the nutrients needed for a healthy diet than any other breakfast cereal on the market today. Thus, when you eat Morning Sunshine, you will know you are eating the most nutritious food now on the market. (C) The number of consumer visits increased more at Countryside Market last year than at any other market in the region. Therefore, Countryside's profits must also have increased more last year than those of any other market in the region. (D) Jerrold's teachers recognize him as the student who has shown more academic improvement than any other student in the junior class this year. Therefore, if Jerrold and his classmates are ranked according to their current academic performance, Jerrold must hold the highest ranking. (E) Margaret Durring's short story "The Power Lunch" won three separate awards for best short fiction of the year. Therefore, any of Margaret Durring's earlier stories certainly has enough literary merit to be included in an anthology of the best recent short fiction.

One sure way you can tell how quickly a new ideafor example, the idea of "privatization" - is taking hold among the population is to monitor how fast the word or words expressing that particular idea are passing into common usage. Professional opinions of whether or not words can indeed be said to have passed into common usage are available from dictionary editors, who are vitally concerned with this question. The method described above for determining how quickly a new idea is taking hold relies on which one of the following assumptions? (A) Dictionary editors are not professionally interested in words that are only rarely used. (B) Dictionary editors have exact numerical criteria for telling when a word has passed into common usage. (C) For a new idea to take hold, dictionary editors have to include the relevant word or words in their dictionaries. (D) As a word passes into common usage, its meaning does not undergo any severe distortions in the process. (E) Words denoting new ideas tend to be used before the ideas denoted are understood.

In 1990 major engine repairs were performed on 10 percent of the cars that had been built by the National Motor Company in the 1970 s and that were still registered. However, the corresponding figure for the cars that the National Motor Company had manufactured in the 1960 s was only five percent. Which one of the following, if true, most helps to explain the discrepancy? (A) Government motor vehicle regulations generally require all cars, whether old or new, to be inspected for emission levels prior to registration. (B) Owners of new cars tend to drive their cars more carefully than do owners of old cars. (C) The older a car is, the more likely it is to be discarded for scrap rather than repaired when major engine work is needed to keep the car in operation. (D) The cars that the National Motor Company built in the 1970 s incorporated simplified engine designs that made the engines less complicated than those of earlier models. (E) Many of the repairs that were performed on the cars that the National Motor Company built in the 1960 s could have been avoided if periodic routine maintenance had been performed.

It takes \(365.25\) days for the Earth to make one complete revolution around the Sun. Long-standing convention makes a year 365 days long, with an extra day added every fourth year, and the year is divided into 52 seven-day weeks. But since 52 times 7 is only 364 , anniversaries do not fall on the same day of the week each year. Many scheduling problems could be avoided if the last day of each year and an additional day every fourth year belonged to no week, so that January 1 would be a Sunday every year. The proposal above, once put into effect, would be most likely to result in continued scheduling conflicts for which one of the following groups? (A) people who have birthdays or other anniversaries on December 30 or 31 (B) employed people whose strict religious observances require that they refrain from working every seventh day (C) school systems that require students to attend classes a specific number of days each year (D) employed people who have three-day breaks from work when holidays are celebrated on Mondays or Fridays (E) people who have to plan events several years before those events occur
