What is the core principle of the Law of Detachment?

Given the statement "If there is lightning, then it is not safe to be outside," and the observation that "Preston sees lightning from the baseball field," what can be concluded?

• Preston should continue playing baseball.

• It is not safe for Preston to be outside.

• Preston should look for lions or aliens.

• The lightning is not dangerous.

If the statement "If there is lightning, then it is not safe to be outside" is true, and we know "It is not safe for Preston to be outside," can we conclude that there is lightning?

• Yes, because the unsafe condition must be due to lightning.

• No, because there could be other reasons why it's not safe.

• Yes, this is an application of the Law of Detachment.

• No, because the Law of Detachment only applies when the conclusion is false.
