Doctor: It is wrong for medical researchers to keep their research confidential, even if the companies for which they work would rather that they do so. If research results are not shared, the development of effective medical treatments may be delayed, and thus humans may suffer unnecessarily.
Which of the following principles, if valid, most helps to justify the doctor's argument?
(A) Medical researchers should never engage in any behavior that they know will cause humans to suffer.
(B) If the most important moral principle is to prevent human suffering, then it is wrong for medical researchers to keep their research confidential.
(C) Medical researchers should not keep information confidential if it is possible that sharing that information would prevent some unnecessary human suffering.
(D) Medical researchers should always attempt to develop effective medical treatments as rapidly as they can while fulfilling their other moral obligations.
(E) It is wrong for any company to ask its medical researchers to keep their research confidential, if failure to share the research might delay development of effective medical treatments.
The conclusion says that:
Sufficient -----> Necessary
If research results are not shared ---> the development of effective medical treatments may be delayed, and thus humans may suffer unnecessarily.
Contrapositive:
If the development of effective medical treatments is not to be delayed, and thus humans may not suffer unnecessarily --> Results should be shared (not kept confidential)
Now what answer choice C states is the contrapositive:
Just tweaked the arrangement a bit:
If it is possible that sharing that information would prevent some unnecessary human suffering, then Medical researchers should not keep information confidential. Matches with the contrapositive of the statement.
Other answer choices:
(A) Medical researchers should never engage in any behavior that they know will cause humans to suffer.
Humans suffer ---> Medical researchers should not engage in that. The choice is no where close to the conclusion or contrapositive of it. Discard.
(B) If the most important moral principle is to prevent human suffering, then it is wrong for medical researchers to keep their research confidential.
Prevent human suffering ---> information to be shared. This answer choice covers the contrapositive but the words used in this answer choice such as most important, wrong are too strong. It's kinda shell game answer.
C) Discussed above.
D and E can be easily eliminated.
