LR Question 24 Explanation

QUESTION TEXT: Explanation must be distinguished from justification…

QUESTION TYPE: Must be True

FACTS:

1. Explanation and justification aren’t the same.
2. An explanation is why we do something and a justification is whether there is a good reason to do something.
3. We may do something for silly reasons even if there was a justification.
4. An action is rational only if the justification is part of the explanation.

ANALYSIS: We can conclude that a rational action needs to have a justifiable explanation.

___________

1. The argument says that all actions have explanations.
2. The reasons have to be justified. And even then, a justifiable explanation is only a necessary condition for rational action.
3. We only know that many psychologists think that sometimes a justification isn’t part of the explanation.
4. We don’t know. We’re not told if there is anything we can’t understand.
5. CORRECT. Explanations are the causes. Reasons are justification. For an action to be rational, justifications must be part of the explanations.

Recap: The question begins with “Explanation must be distinguished from justification”. It is a Must be True question. Learn more about LSAT MBT questions in our guide to LSAT Logical Reasoning question types.
