You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you will be given two sentences separated by "because". You should decide whether the first sentence can be the result of the second sentence. If you can see a possible cause and effect relationship, answer with "plausible", otherwise answer with "not plausible".

Solution: not plausible
