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: What is the difference between "Did you find?" and "Have you found?" When should I use the first sentence, and when the second one?
Answer: Did you find is the simple past and indicates that you are no longer looking for it. Have you found is the present perfect and indicates a link with the present, specifically, that you could still be looking for it.
Output:
yes
