You will be given a definition of a task first, then some input of the task.
Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.

Question: Suppose I tell something to my companion and I want to make sure he understands me. I thought I may simply ask "Do you understand me?". But recently I heard that in such cases I should ask "Does that make sense?" instead. Is this true? Which option is appropriate to use in business communication?
Answer: I generally go with a simple: Is this explanation okay..? As it sounds neutral and encourages the receiver to provide feedback. If I used pronouns while asking for feedback, like "Did you understand..", "Did I explain this..", .. it generally makes the receiver feel like you might take their feedback negatively or take offense if they were not able to understand.
Output:
no
