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.

Input: Consider Input: Question: Is it more correct to say a computer program is erroring out, or it is erring out? Or are both statements grammatically incorrect? 
Answer: I would say that neither one is correct (from a programmer). You could say "... has an error and crashed ..." ("crashed" being the technical term for a program that suddenly stops or breaks down - except for airplane-related programs). But that's American usage - British programmers may differ.

Output: no


Input: Consider Input: Question: In computer programming, when you append a "string" to another, you add it to the end of the former string. E.g. String string1 = "abcd"; String string2 = "efgh"; Appending the two strings would give "abcdefgh" But what if I wanted to add string2 before string1 to have the result: "efghabcd" What would be a good name for that that reverse operation? What is the opposite of "append"? 
Answer: Prepend, insert, pre-attach. Some programming languages have additional functions that can add strings in various positions, including the start of another string. For example: slice, push, at.

Output: no


Input: Consider Input: Question: Just to clarify, I'm not talking about the Lush product of the same name. In Australia, the washing up fairy is a mythical creature. People leave their dishes unwashed overnight, and lo and behold, the next morning the dishes are clean thanks to the washing up fairy. Sadly, she (I assume it's a she) is more often noted in her absence than her presence. As in "The washing up fairy didn't come, I'll have to do the dishes now." An example of her being mentioned: Her theory is simple we must replace the behaviours we don't want with those we do. For example, leaving dirty dishes on the kitchen bench for the washing-up fairy to tidy should be replaced with loading the dirty dishes in the dishwasher. Her existence has been documented neither by Wiktionary nor Urban Dictionary. Is her distribution limited to Australia, and presumably New Zealand, plus the households of those who have moved from these countries? 
Answer: I'm in the U.S., and I've never heard of the Washing-Up Fairy. Still, using a fairy to explain an unexplained yet serendipitous discovery is not unheard of. When I Googled "a fairy came and cleaned", I found: my mother would call me the next day, "Oh! a Fairy came and cleaned the house" [in a Yahoo! answer] "Let's pretend a fairy came and cleaned up your room." [from a parenting book] Every morning, it's as if a fairy came and cleaned the house for me. [from a Roomba vacuum review on amazon.com] Miraculously, when I came downstairs I found that a fairy came and cleaned up the party mess inside (thank you Daddy!) [from a 2004 blog] So, such "pay-it-forward" cleaning acts of kindness are often attributed to fairy folk. I never realized until today, though, that the Tooth Fairy had a cousin called the Washing Up Fairy, at least by those Down Under.


Output: yes
