Detailed explanation-4: -Logical evidence is used proven or disprove an idea using logic. Deductive reasoning may be used to come to a conclusion to provide logical evidence. For example, “All men are mortal. Harold is a man. Therefore, Harold is mortal."

Detailed explanation-5: -A valid argument may still have a false conclusion. When we construct our arguments, we must aim to construct one that is not only valid, but sound.
