When workers do not find their assignments challenging, they become bored and so achieve less than their abilities would allow. On the other hand, when workers find their assignments too difficult, they give up and so again achieve less than what they are capable of achieving. It is, therefore, clear that no worker's full potential will ever be realized. Which one of the following is an error of reasoning contained in the argument? (A) mistakenly equating what is actual and what is merely possible (B) assuming without warrant that a situation allows only two possibilities (C) relying on subjective rather than objective evidence (D) confusing the coincidence of two events with a causal relation between the two (E) depending on the ambiguous use of a key term

Short Answer

Expert verified
The argument assumes without warrant that there are only two possibilities, making (B) the correct answer.

Step by step solution

01

Understand the Argument's Structure

The argument claims that no worker can reach their full potential because they will either get bored with easy tasks or give up on difficult ones, thus never achieving their maximum capability. We need to identify any assumptions or logical flaws in this reasoning.
02

Identify Potential Logical Flaws

Analyze if the argument makes any assumptions, fails to consider other possibilities, or misuses terms. The scenario suggests a binary condition: tasks are either too easy or too hard. Consider if there are other potential scenarios not accounted for by the argument.
03

Examine Each Answer Choice

Evaluate each option to see which best describes the argument's flaw: - **(A)** Mistakenly equates what is real with what is possible. - **(B)** Assumes only two possibilities: easy or difficult tasks. - **(C)** Uses subjective rather than objective reasoning. - **(D)** Mistakes coincidence for causation. - **(E)** Uses a term ambiguously.
04

Match Flaws with Answer Choices

The argument does not address the possibility of an optimal challenge. **(B):** assumes without warrant that there are only two possibilities, overlooks the possibility of assignments that are neither too easy nor too hard.
05

Conclusion: Choose the Correct Answer

The flaw in the argument is that it assumes only two possible states for task difficulty without considering other scenarios. Therefore, the error of reasoning in the argument is best described by answer choice (B).

Key Concepts

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

Argument Structure
In logical reasoning, understanding the structure of an argument is crucial to identifying its strengths and weaknesses. An argument is typically composed of premises and a conclusion.
The premises provide the foundational statements or reasons supporting the conclusion. When analyzing the provided exercise, we can break down the argument into these components:
  • Premise 1: If assignments are not challenging enough, workers become bored and underperform.
  • Premise 2: If assignments are too challenging, workers give up and underperform.
  • Conclusion: Therefore, no worker will ever achieve their full potential due to the nature of assignments.
Recognizing these components makes it easier to see where the argument may fall short. Here, the conclusion that no worker can achieve their full potential is drawn from two extremes without considering other potential scenarios. Identifying these parts allows us to spot logical fallacies or erroneous assumptions embedded within the argument.
Assumptions in Reasoning
Assumptions play a critical role in logical reasoning. They are unstated ideas or beliefs that the argument relies on to hold true. In the given argument about workers and task difficulty, the assumptions significantly impact the validity of the conclusion. One key assumption here is that there are only two possible conditions for task assignments: tasks that are too easy and tasks that are too difficult. This implies that the arguer believes no middle ground exists where tasks are appropriately challenging.
Identifying assumptions means you should ask yourself what the argument presupposes without evidence. If these assumptions are proven false or questionable, the argument's conclusion might not logically follow. In this case, questioning the assumption helps reveal a potential flaw: the argument does not consider the possibility of tasks being optimally challenging, which would allow workers to utilize their full potential. By spotlighting such assumptions, you can critically assess how they influence the strength and coherence of the argument.
Binary Conditions
Binary conditions are a common element in reasoning, wherein a situation is presented as having only two exclusive options or states. This all-or-nothing approach can sometimes oversimplify complex issues. In the exercise provided, the argument assumes a binary condition regarding task difficulty: tasks are either too easy, leading to boredom, or too difficult, leading to futility. This binary framework ignores any alternative possibilities, such as tasks that are just right, which could engage workers without overwhelming them.
The flaw in adopting a binary condition is that it artificially narrows down the problem's scope. It can lead to the false dilemma fallacy, where only two extreme choices are considered, ignoring any middle-ground solutions. This can be problematic as it fails to reflect the true complexity of real-life situations. By acknowledging binary conditions in arguments, you can better probe the completeness and depth of the reasoning. This understanding helps to discover if the argument indeed provides a thorough analysis of the issue or if it limits itself erroneously by overlooking other viable alternatives.

Of the following, which one would the author most likely say is the most troublesome barrier facing working parents with primary child-care responsibility? (A) the lack of full-time jobs open to women (B) the inflexibility of work schedules (C) the low wages of part-time employment (D) the limited advancement opportunities for nonprofessional employees (E) the practice of allocating responsibilities in the workplace on the basis of gender

Light utility trucks have become popular among consumers who buy them primarily for the trucks' rugged appearance. Yet although these trucks are tough-looking, they are exempt from the government's car-safety standards that dictate minimum roof strength and minimum resistance to impact. Therefore, if involved in a serious high-impact accident, a driver of one of these trucks is more likely to be injured than is a driver of a car that is subject to these government standards. The argument depends on the assumption that (A) the government has established safety standards for the construction of light utility trucks (B) people who buy automobiles solely for their appearance are more likely than other people to drive recklessly (C) light utility trucks are more likely than other kinds of vehicles to be involved in accidents that result in injuries (D) the trucks' rugged appearance is deceptive in that their engines are not especially powerful (E) light utility trucks are less likely to meet the car-safety standards than are cars that are subject to the standards

Many major scientific discoveries of the past were the product of serendipity, the chance discovery of valuable findings that investigators had not purposely sought. Now, however, scientific research tends to be so costly that investigators are heavily dependent on large grants to fund their research. Because such grants require investigators to provide the grant sponsors with clear projections of the outcome of the proposed research, investigators ignore anything that does not directly bear on the funded research. Therefore, under the prevailing circumstances, serendipity can no longer play a role in scientific discovery. Which one of the following is an assumption on which the argument depends? (A) Only findings that an investigator purposely seeks can directly bear on that investigator's research. (B) In the past few scientific investigators attempted to make clear predictions of the outcome of their research. (C) Dependence on large grants is preventing investigators from conducting the type of scientific research that those investigators would personally prefer. (D) All scientific investigators who provide grant sponsors with clear projections of the outcome of their research receive at least some of the grants for which they apply. (E) In general the most valuable scientific discoveries are the product of serendipity.

Many environmentalists have urged environmental awareness on consumers, saying that if we accept moral responsibility for our effects on the environment, then products that directly or indirectly harm the environment ought to be avoided. Unfortunately it is usually impossible for consumers to assess the environmental impact of a product, and thus impossible for them to consciously restrict their purchases to environmentally benign products. Because of this impossibility there can be no moral duty to choose products in the way these environmentalists urge, since Which one of the following principles provides the most appropriate completion for the argument? (A) a moral duty to perform an action is never based solely on the effects the action will have on other people (B) a person cannot possibly have a moral duty to do what he or she is unable to do (C) moral considerations should not be the sole determinants of what products are made available to consumers (D) the morally right action is always the one whose effects produce the least total harm (E) where a moral duty exists, it supersedes any legal duty and any other kind of duty

For the writers who first gave feudalism its name, the existence of feudalism presupposed the existence of a noble class. Yet there cannot be a noble class, properly speaking, unless both the titles that indicate superior, noble status and the inheritance of such titles are sanctioned by law. Although feudalism existed in Europe as early as the eighth century, it was not until the twelfth century, when many feudal institutions were in decline, that the hereditary transfer of legally recognized titles of nobility first appeared. The statements above, if true, most strongly support which one of the following claims? (A) To say that feudalism by definition requires the existence of a nobility is to employ a definition that distorts history. (B) Prior to the twelfth century, the institution of European feudalism functioned without the presence of a dominant class. (C) The fact that a societal group has a distinct legal status is not in itself sufficient to allow that group to be properly considered a social class. (D) The decline of feudalism in Europe was the only cause of the rise of a European nobility. (E) The prior existence of feudal institutions is a prerequisite for the emergence of a nobility, as defined in the strictest sense of the term.
