Read the argument and the instructions that follow it, and then make any notes that will help you plan your response. Write your response on a separate sheet of paper. If possible, type your essay on a word processor. Observe the 30-minute time limit.
The following letter was printed in a medical journal:
Many nonprescription drugs can cause serious side effects, particularly when taken in conjunction with other drugs or in large quantities. If these potentially harmful nonprescription drugs were sold only by prescription, then a doctor or pharmacist would be able to explain the possible side effects of the drug and would also be able to monitor the quantity of the drug purchased, thereby decreasing the chance that a person would take too much of the drug. Therefore, any drug with potentially serious side effects should be sold only by prescription.
Discuss how well reasoned you find this argument. In your discussion, be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative examples or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.
