Teacher: You're given a sentence and your task is to classify whether the sentence is acceptable or not. Any sentence which is grammatically correct, has a naturalistic text, is written by a native speaker and which minimizes superfluous content is acceptable, otherwise unacceptable. If the sentence is acceptable then write "acceptable", otherwise "unacceptable".
Teacher: Now, understand the problem? If you are still confused, see the following example:
Our friends won't buy this analysis, let alone the next one we propose.
Solution: acceptable
Reason: The sentence is easy to understand where a person talks about not being convinced of the analysis. So, it's acceptable.

Now, solve this instance: Wash yourself.
Student:
acceptable
