You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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".

Our friends won't buy this analysis, let alone the next one we propose.
Solution: acceptable
Why? The sentence is easy to understand where a person talks about not being convinced of the analysis. So, it's acceptable.

New input: Brenda and Molly agreed.
Solution:
acceptable
