LSAT Practice Test

In Formal Logic "Neither....nor" identifies:

1. Excluded Middle

2. Mutually Exclusive

3. Sufficient Condition

4. Necessary Condition

The correct answer is: Mutually Exclusive

In formal logic, the phrase "Neither...nor" is used to indicate that two conditions are mutually exclusive. This means that both conditions cannot be true at the same time. Therefore, the correct answer is B - Mutually Exclusive. Options A, C, and D are incorrect: A. Excluded Middle does not relate to the phrase "Neither...nor." The Excluded Middle principle states that a statement must be either true or false with no middle ground. C. Sufficient Condition refers to a condition that, if present, guarantees the occurrence of another condition. This is different from the concept of two conditions being mutually exclusive. D. Necessary Condition is a condition that must be present for another condition to occur, which is also distinct from the idea of conditions being mutually exclusive.
