Which of the following is most similar in its reasoning to the argument above?

1. Whenever it rains outside, the lawn grass becomes wet. The grass is now wet, so it must surely have rained recently in the area.
2. If the engine is running, then the dashboard warning light stays off. The light is currently off, so the engine must be running now.
3. If you study hard for the test, then you will surely pass the exam. You passed the exam, so you must have studied very hard for it beforehand.
4. If the cake were fully baked, a toothpick would come out clean. The toothpick is covered in batter; therefore, the cake is not fully baked.
5. All cats have whiskers as a defining physical feature of their own. This particular animal has whiskers, so it must therefore be a cat of some kind.
