It is proposed to allow the sale, without prescription, of a medication that physicians currently prescribe to treat the common ear inflammation called “swimmer’s ear.” The principal objection is that most people lack the expertise for proper self-diagnosis and might not seek medical help for more serious conditions in the mistaken belief that they have swimmer’s ear. Yet in a recent study, of 1,000 people who suspected that they had swimmer’s ear, 84 percent had made a correct diagnosisa slightly better accuracy rate than physicians have in diagnosing swimmer’s ear. Thus, clearly, most people can diagnose swimmer’s ear in themselves without ever having to consult a physician.

Summarize Argument
The author concludes that most people can diagnose swimmer’s ear in themselves without ever needing to consult a physician. As support for this conclusion, the author cites a recent study where 84% of a sample of 1,000 people who believed that they had swimmer’s ear made an accurate diagnosis. The author also notes that this 84% accurate diagnosis rate is slightly higher than doctors’ accuracy.

Notable Assumptions
The author assumes that a high rate of successful self diagnosis supports the idea that people never have to see a doctor for swimmer’s ear; we don’t know that the people in the study had never seen a doctor for swimmer’s ear.

A
Cases in which swimmer’s ear progresses to more serious infections are very rare.
The argument is concerned with whether or not doctors are required for accurate diagnosis of swimmer’s ear. The argument is not concerned with severity of infections, so this information does not weaken the argument.
B
Most of those who suspected incorrectly that they had swimmer’s ear also believed that they had other ailments that in fact they did not have.
(B) provides information about the 16% who made an incorrect self-diagnosis of swimmer’s ear. The argument is about the high rate of accurate self-diagnosis, so this information does not weaken the argument.
C
Most of the people who diagnosed themselves correctly had been treated by a physician for a prior occurrence of swimmer’s ear.
This information attacks the argument’s key assumption that, because of the high rate of accurate self-diagnosis, most people can diagnose themselves without ever seeing a doctor. (C) says that previous visits to a doctor may have informed these accurate self-diagnoses.
D
Physicians who specialize in ear diseases are generally able to provide more accurate diagnoses than those provided by general practitioners.
This does not change the fact that self-diagnoses are more accurate than doctors’ diagnoses in general. The key support for the argument is that self-diagnoses are highly accurate. (D) does not weaken the argument that most people can self diagnose without ever seeing a doctor.
E
For many people who develop swimmer’s ear, the condition disappears without medical or pharmaceutical intervention.
The argument is concerned with diagnosis, not treatment, of swimmer’s ear.

Parent: I had tried without success to get my young child to brush her teeth. I had hoped that she would imitate me, or that she would be persuaded by reason to brush her teeth. Then, I made a point of brushing her teeth for her immediately before reading her a story before her naps and at night. After several weeks, when I would pick up a storybook at these times, she began automatically to retrieve her toothbrush and brush her teeth herself.

Summary

A parent has tried to get a young child to brush their teeth. The parent hoped that the child would imitate them or that the child could be persuaded to do so, but both of these attempts failed to get the child to brush their teeth. Then, the parent started brushing the child’s teeth immediately before reading the child a nighttime story. After several weeks, whenever the parent picked up a storybook the child began to automatically brush their teeth on their own.

Strongly Supported Conclusions

Young children adopt a behavior through habit and repetition.

A
Children are most effectively taught to do something by someone’s setting an example.

We don’t know whether children are most effectively taught through example. In the stimulus, the parent attempted to set an example for the child and the example was ineffective in teaching the child to brush their teeth.

B
Children more readily adopt a behavior through habit and repetition than through other means.

In the stimulus, the child learned to brush their teeth through habit and repetition as opposed to persuasion and an example set by their parent.

C
Children are too young to understand rational arguments for adopting a behavior.

We don’t know whether children do not understand arguments for rationale behavior. In the stimulus the parent states that persuasion did not work, but this could be for reasons other than the child’s lack of understanding.

D
Children often imitate the behavior of others rather than listening to reason.

We don’t know whether children often imitate the behavior of others. In the stimulus, the parent attempted to teach a child to brush their teeth by setting an example and the child failed to adopt the behavior.

E
Children ordinarily act contrary to their parents’ expectations in order to get more attention.

We don’t know whether children act a certain way in order to get more attention. In the stimulus the child did act contrary to the parent’s expectations, but this could be for reasons other than the child seeking more attention.

Raymond Burr played the role of lawyer Perry Mason on television. Burr’s death in 1993 prompted a prominent lawyer to say “Although not a lawyer, Mr. Burr strove for such authenticity that we feel as if we lost one of our own.” This comment from a prestigious attorney provides appalling evidence that, in the face of television, even some legal professionals are losing their ability to distinguish fiction from reality.

Summarize Argument

The author concludes that even some legal professionals cannot tell fiction from reality because of television. As evidence, she provides a quote from an attorney following the death of an actor who played a lawyer on TV: “Although not a lawyer, Mr. Burr strove for such authenticity that we feel as if we lost one of our own.”

Identify and Describe Flaw

The author’s reasoning is flawed because her evidence contradicts her conclusion. She concludes that some lawyers can’t tell reality from fiction, but her example shows a lawyer who can. The lawyer she quotes says that the actor felt like “one of our own,” even though the actor was not a lawyer. This shows that the lawyer could in fact tell reality from fiction.

A
takes the views of one lawyer to represent the views of all lawyers

This is the cookie-cutter flaw of “hasty generalization.” But the author concludes that some legal professionals can’t distinguish fiction from reality, not that all legal professionals can’t.

B
criticizes the lawyer rather than the lawyer’s statement

This is the cookie-cutter flaw of “attacking the source,” but the author doesn’t make this mistake. She simply draws a conclusion about the lawyer based on the lawyer’s statement. She isn’t making an unwarranted attack on the lawyer.

C
presumes that the lawyer is qualified to evaluate the performance of an actor

The author never addresses whether the lawyer is qualified to evaluate the actor’s performance. She just argues that the lawyer thinks that the actor was a real lawyer. Whether or not he was a good actor is irrelevant.

D
focuses on a famous actor’s portrayal of a lawyer rather than on the usual way in which lawyers are portrayed on television

“The usual way in which lawyers are portrayed” on TV is irrelevant to the author’s argument. She’s just claiming that one lawyer’s comment about one actor’s portrayal shows that some legal professionals can’t distinguish reality from fiction.

E
ignores the part of the lawyer’s remark that indicates an awareness of the difference between reality and fiction

In his comment about the actor, the lawyer explicitly says, “Although not a lawyer...,” showing that the lawyer can distinguish reality from fiction. The author ignores this when she concludes that, based on this quote, some lawyers cannot distinguish reality from fiction.

Formal performance evaluations in the professional world are conducted using realistic situations. Physicians are allowed to consult medical texts freely, attorneys may refer to law books and case records, and physicists and engineers have their manuals at hand for ready reference. Students, then, should likewise have access to their textbooks whenever they take examinations.

A
cites examples that are insufficient to support the generalization that performance evaluations in the professional world are conducted in realistic situations
The strength of the author’s examples is irrelevant. We’re focusing on whether the author’s reasoning for arguing that students should have access to textbooks during exams is sound.
B
fails to consider the possibility that adopting its recommendation will not significantly increase most students’ test scores
The effect the author’s recommendation would have on test scores is irrelevant to whether the reasoning in the author’s argument is sound.
C
neglects to take into account the fact that professionals were once students who also did not have access to textbooks during examinations
We don’t know if the author took this into account, but regardless, the fact that professionals were once students has no bearing on the strength of the author’s argument that students should have access to textbooks during exams.
D
neglects to take into account the fact that, unlike students, professionals have devoted many years of study to one subject
We don’t know if the author took this into account, but regardless, the fact that professionals have devoted years to studying one subject has no bearing on the soundness of the author’s reasoning.
E
fails to consider the possibility that the purposes of evaluation in the professional world and in school situations are quite dissimilar
This describes a possibility that the author ignores. If the purposes of evaluation in the professional world differ from those in school, it may be well-reasoned that students aren’t allowed access to textbooks even though professionals have access to reference materials.
