LSAT Practice Test

What is the primary role of "Guarantees" in formal logic terminology?

1. Inference

2. Certainty

3. Probability

4. Necessity

The correct answer is: Necessity

In formal logic terminology, the primary role of "Guarantees" is to signify necessity. When a guarantee is present in a logical argument, it indicates that a certain conclusion must necessarily follow from the premises. This is different from inference, which involves drawing conclusions based on the premises, certainty, which implies absolute assurance, and probability, which relates to the likelihood of something occurring. Therefore, the correct answer is D: Necessity.
