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.
