The reasoning in which one of the following is most similar to the reasoning in the argument above?

1. Either the sky will stay cloudy or it will turn fully sunny later today. It is presently cloudy outside, so the sky will not turn sunny.
2. The patient has either a viral or a bacterial infection. The test for the virus came back negative. Therefore, it is a bacterial infection.
3. To reach the distant offshore island you may take either a boat or a plane. You clearly took the boat, so you did not take the plane.
4. For your main meal you may have either the soup or the fresh garden salad. You deliberately chose the salad, so you cannot have the soup.
5. The delay was caused by the weather, and such weather delays are quite common in the winter months, so most winter delays are weather-related.
