Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no".

Example Input: Question: As per title of the question, I see this a lot. "We will release the product when issue 51 has been finalized." "We are waiting for it to be finalized." Is this just a case of people trying to sound professional with corporate jargon , or is there a real difference between 'finish' and 'finalize'? 
Answer: "finishing" means reaching the end of some process, "finalizing" means declaring the end of some process. After finishing, nothing needs to be done any more, after finalizing, nothing is to be done any more. Finishing a specification means ending the process of drafting it, finalizing a specification means ending the process of refining it into a state fit for formal adoption.
Example Output: no

Example Input: Question: Exact Duplicate: Can anyone tell me what the suffix "-fu" stands for in the following sentence? I was reading an article on MSDN where I found a mention to google-fu. It says, "To search for C++ delimeters and code snippets is going to take a little Google-fu on the reader's part." what does google-fu mean? 
Answer: Google-fu is defined as "skill in using search engines (especially Google) to quickly find useful information on the Internet." It is a somewhat tongue-in-cheek reference to kung-fu, which is generally perceived as requiring a high degree of skill to master in the western hemisphere. In the example sentence you provided, the author is suggesting that the expected results are somewhat difficult to attain and you will need to use diligence when searching. I used a bit of Google-fu to research this answer.
Example Output: yes
