Official Solution:
Discontinuation of most habit forming drugs cause emotional depression. While recreational activities can help reduce the amount of emotional depression caused while discontinuing such drugs, some emotional depression is unlikely to be preventable.
The information above most strongly supports which one of the following?
A. A physician should not discontinue any habit forming drug for a patient if that patient is already emotionally depressed.
B. People who are suffering from emotional depression should not ask their doctors to discontinue a habit forming drug.
C. At least some patients who discontinued habit forming drugs were emotionally depressed as a result of the discontinuation.
D. The emotional depression experienced by patients discontinuing habit forming drugs should be attributed to lack of recreational activities.
E. All patients discontinuing habit forming drugs should engage themselves in recreational activities to prevent themselves from emotional depression.
General Approach
The general approach to Critical Reasoning questions on the GMAT involves understanding the argument, breaking down its constituent parts (premises, conclusion, etc.), and then analyzing the answer choices in the light of these. Here, the argument suggests a causal relationship between discontinuation of certain habit-forming drugs and subsequent emotional depression, albeit tempered by the possibility of reduction through recreational activities. The answer should logically and necessarily follow from the given information, without reaching or making unwarranted assumptions.
Correct Answer
C) At least some patients who discontinued habit-forming drugs were emotionally depressed as a result of the discontinuation. The argument explicitly claims that discontinuation of most habit-forming drugs can cause emotional depression, while also acknowledging that this effect can be somewhat mitigated by recreational activities. However, it additionally asserts that some degree of emotional depression is inevitably going to be unavoidable. From this, it is reasonable and valid to infer that some patients discontinuing such drugs would still experience emotional depression to some extent – just as answer choice C states.
Incorrect Answers
A) A physician should not discontinue any habit-forming drug for a patient if that patient is already emotionally depressed. This choice extrapolates too much from the argument. Nothing is mentioned about the role of a physician or about how the initial state of a patient's emotional health should impact decisions in their treatment. This statement is neither warranted nor supported by the given information.
B) People who are suffering from emotional depression should not ask their doctors to discontinue a habit-forming drug. Again, this choice overreaches. It presumes a physician-patient interaction that the argument doesn't address, and makes excessively broad suggestions that are not substantiated by the provided premises.
D) The emotional depression experienced by patients discontinuing habit-forming drugs should be attributed to lack of recreational activities. This is incorrect and, in fact, directly contradicts a portion of the argument, which clearly indicates that emotional depression is a result of discontinuing the drugs, not a lack of recreational activities.
E) All patients discontinuing habit-forming drugs should engage themselves in recreational activities to prevent themselves from emotional depression. This absolute statement does not fit the argument's more measured tone. The argument states that recreational activities can help, but it doesn't go as far as to say that all patients need to do so or that it would completely prevent emotional depression. Therefore, this statement goes beyond the scope of the argument.
