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.

Let me give you an example: Question: What's the difference between the following examples: Neither of my teachers are mathematicians. None of my teachers are mathematicians.
Answer: Neither - not either - implies that there is a choice of only two. So 'neither of my teachers' is only correct if there are exactly two teachers, 'none of my teachers' can be any number.
The answer to this example can be: yes
Here is why: The answer is well in context with the question and gives a proper explanation to resolve it. Hence, the output "yes" is correct.

OK. solve this:
Question: I am developing some software where users are assigned tasks. They will see a date and time for when they were assigned to the task, but if they were later removed from the task, there will be a date and time for that also. 01/02/14 - Assigned 03/02/14 - Unassigned I'm pretty sure unassigned isn't correct. I suppose the task itself could be in a state of being unassigned, but the user wasn't "unassigned" from it. Notes: I don't want to use the word "removed", as I don't think it conveys the correct meaning and also sounds too harsh. I would like to avoid using a word your average person would never have heard of, as this isn't very user-friendly from a software point of view.
Answer: "revoked", "withdrawn", "retracted", or simply "reassigned".
Answer:
yes
