Commentator: If a political administration is both economically successful and successful at protecting individual liberties, then it is an overall success. Even an administration that fails to care for the environment may succeed overall if it protects individual liberties. So far, the present administration has not cared for the environment but has successfully protected individual liberties.

Summary

The stimulus can be diagrammed as follows:

Notable Valid Inferences

If the present administration is economically successful, then it is an overall success.

A
The present administration is economically successful.

Could be false. Based on the information in the stimulus, there’s no reason to believe that the administration is economically successful or that it is not.

B
The present administration is not an overall success.

Could be false. The stimulus tells us that the present administration satisfies half the sufficient condition for overall success, and it does not tell us whether or not it satisfies the other half. If it is economically successful, then it’s an overall success and (B) is false.

C
If the present administration is economically successful, then it is an overall success.

Must be true. We know that the present administration has protected individual liberties, and (C) tells us that it’s also been economically successful. As shown below, these two conditions combine to form the sufficient condition for overall success.

D
If the present administration had been economically successful, it would have cared for the environment.

Could be false. In this question, caring for the environment is a bit of a red herring: it is not part of the sufficient condition or the necessary condition, and we can neither use it to draw a valid conclusion nor conclude anything about it.

E
If the present administration succeeds at environmental protection, then it will be an overall success.

Could be false. In this question, caring for or protecting the environment is a bit of a red herring: it is not part of the sufficient condition or the necessary condition, and we can neither use it to draw a valid conclusion nor conclude anything about it.
