LSAT Practice Test

If A is in the fourth position and B is in the seventh position, how is this condition represented in formal logic?

1. A₄ --> B₇

2. B₇ --> A₄

3. A ̰₄ --> B ̰₇

4. B ̰₇ --> A ̰₄

The correct answer is: A₄ --> B₇

In formal logic, conditional statements are typically represented as "if-then" statements. Therefore, the correct way to represent the condition where A is in the fourth position and B is in the seventh position is by stating it as "If A is in the fourth position, then B is in the seventh position," which translates to A₄ --> B₇. This notation indicates that the presence of A in the fourth position implies the presence of B in the seventh position. The other options are incorrect because they do not accurately capture the relationship between A being in the fourth position and B being in the seventh position as a conditional statement.
