LSAT Practice Test

How does the Denial Test function in formal logic?

1. A. Confirms conclusions

2. B. Validates sufficiency

3. C. Denies answer choices to check if they affect the conclusion

4. D. Establishes necessity

The correct answer is: C. Denies answer choices to check if they affect the conclusion

The Denial Test, in formal logic, functions by denying answer choices to check if they have an effect on the conclusion. By systematically denying each answer choice and observing if it undermines the conclusion, one can determine the validity and strength of the argument. This process helps in evaluating the significance and relevance of each answer choice in relation to the conclusion being drawn. In the context of the options provided: - Option A, confirming conclusions, does not align with the purpose of the Denial Test, which is to challenge the impact of answer choices on the conclusion. - Option B, validating sufficiency, is not the primary function of the Denial Test, which focuses on testing the effect of denying answer choices. - Option D, establishing necessity, is not the main goal of the Denial Test, as it is more concerned with evaluating the impact of negating answer choices on the conclusion. Therefore, option C, denying answer choices to check if they affect the conclusion, correctly articulates the function of the Denial Test in formal logic.
