LR Question 15 Explanation, by LSATHacks

QUESTION TEXT: If all works of art evoke intense feelings, and this sculpture…

QUESTION TYPE: Parallel Reasoning

CONCLUSION: Either the sculpture is not art or the premise about art (it always causes intense feelings) is incorrect.

REASONING: If all art evokes intense feelings (A) and this sculpture is art (B), then it will evoke intense feelings. But it doesn’t evoke them. So either A or B is incorrect.

ANALYSIS: The correct answer will have two conditions which lead to a conclusion, if they are true. But the conclusion does not occur. So one of the conditions must be false.

___________

1. This is almost right, but it says biology class is not a class. It should say it’s not cancelled. If it isn’t a class, then it still could be true that it is cancelled or that all classes are cancelled.
2. This is also almost right, but the conclusion should be “or,” not “and.” Both conditions aren’t proven wrong just because the research is not significant.
3. CORRECT. This is exactly right. The fact that beta-carotene is not safe in large doses means that one of our two initial premises must be incorrect.
4. This forgets to mention that it could also be true that clinical psychology is a science, but not all sciences rely on math.
5. The structure is different. Here one condition leads to two conclusions. It is true that some classes are not cancelled, and the library may or may not be open. But simply being a good argument is not enough for this to be the right answer.
