Medical ethicist: Medical schools should not allow their students to accept even minor gifts from pharmaceutical companies. When psychological resesarchers gave medical students small promotional gifts with a drug brand logo, those students' favourable attitude toward the brand increased. This shows that such gifts can bias students toward certain brands. In their future careers as doctors, this could lead them to make prescription choices that are not in patients' best interests.
Which of the following could most accurately express the main conclusion of the medical ethicist's argument?
In an argument, the main conclusion is the final conclusion that is supported by everything else in the argument. So, to find the correct answer to this question, we have to analyze the argument to see what conclusion is supported by everything else.
A. No medical school should allow its students to accept even minor gifts from pharmaceutical companies.
This choice says in a slightly different way the same thing the first sentence of the passage says. So, lets see whether the first sentence states the main conclusion by analyzing the structure of the argument.
Medical schools should not allow their students to accept even minor gifts from pharmaceutical companies.
This first statement of the argument could be the main conclusion if it's supported by all the other statements.
When psychological resesarchers gave medical students small promotional gifts with a drug brand logo, those students' favourable attitude toward the brand increased.
This is simply stated as fact and is not supported by any other statement in the passage. So, it can't be the main conclusion.
This shows that such gifts can bias students toward certain brands.
"This shows that" means "this supports the conclusion that." So, "such gifts can bias students toward certain brands," is a conclusion supported by the previous statement.
However, it's not the main conclusion since, as we'll see, it helps to support the first statement in the passage. So, it's not the final conclusion.
In their future careers as doctors, this could lead them to make prescription choices that are not in patients' best interests.
Notice that, while this statement is related to the previous statement, it's not supported by the previous statement. Rather, this statement expresses an opinion of the medical ethicist's for which no support is provided. So, this statement cannot be the main conclusion.
Meanwhile, this statement supports the first statement of the passage. After all, the fact that gifts biasing students toward certain brands could lead them to make prescription choices that are not in patients' best interests logically supports the conclusion that "Medical schools should not allow their students to accept even minor gifts from pharmaceutical companies."
So, we see that the first sentence of the passage states the main conclusion. Thus, since this choice says the same thing the first sentence of the passage says, this choice accurately expresses the main conclusion of the medical ethicist's argument.
Keep.
B. Even minor gifts from pharmaceutical companies bias medical students toward certain pharmaceutical brands.
"Minor gifts" in this choice means the same thing as "small promotional gifts" in the argument. So, since "such gifts" in the argument refers to "small promotional gifts, "this choice means basically the same thing as "such gifts can bias students toward certain brands," in the argument.
As we saw in our analysis of the argument for choice (A), "such gifts can bias students toward certain brands," is a conclusion supported by another statement in the passage.
At the same time, we also saw that ""such gifts can bias students toward certain brands," is not the main conclusion since it in turn helps to support the first statement in the passage.
So, this choice does not express the main conclusion.
Eliminate.
C. A bias toward certain pharmaceutical brands could lead doctors to make prescription choices that are not in patients' best interests.
As we saw in our analysis of choice (A), the final statement of the argument, which expresses basically what this choice expresses, is not a supported conclusion. Rather, it's an unsupported opinion of the medical ethicist's that supports the first statement of the passage.
Eliminate.
D. Gifts from pharmaceutical companies to medical students inappropriately influence those students in their future careers as doctors.
Notice that the argument is about what experimental results indicate. They indicate that "gifts can bias students" and that "this could lead them to make prescription choices that are not in patients' best interests."
So, the argument is about what "can" and "could" occur. It's not about what actually occurs presently, as in, the argument does not indicate that, as this choice says, gifts from pharmaceutical companies do in fact influence students.
So, this choice is not the main conclusion of the argument since this choice is not supported by the statements in the argument.
Eliminate.
E. Research found that small promotional gifts with a drug brand logo increased medical students' favourable attitude toward that brand.
As we saw in our analysis of the argument for choice (A), the fact that "When psychological resesarchers gave medical students small promotional gifts with a drug brand logo, those students' favourable attitude toward the brand increased," is not a conclusion of the argument. Rather, it provides support for a conclusion that in turn supports the main conclusion.
Eliminate.
