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: How did 7 come to be an abbreviation for 'and' in Old English? is a beautiful question about the Tiroian "et", which is now the "" character 1. My question is what impact did the association of this 7-like-glyph have on the eventual placement of keyboards placing the & on Shift+7 combination? The Wikipedia article on the QUERTY keyboard shows that the ampersand was a separate key in the bottom left of the keyboard in the original patent application drawings. The patent was filed in 1878. The Das Keyboard blog shows a Full Duplex keyboard (with separate keys for upper and lower case letters) from 1897 with no ampersand key at all. I have not yet been able to find a reference to the first keyboard to place the ampersand and 7 together. The Wiki article on the ampersand only mentions that it is usually keyed via Shift+7, but occasionally on 6 or 8 instead. Dvorak layouts appear to share similar associations between 7 and &. So is it a coincidence? Or is there some association? 1 This looks really different in the EL&U site fontface. See the linked question or the Wikipedia article for more faithful renderings. 
Answer: Although the 7 was the ampersand on IBM's standard keyboard layout, that is hardly universal. The first nine printable characters in ASCII are ! " # $ % & ' ( ), which should give a good clue as to what the top row of a teletype keyboard looked like. On many early teletypes and terminals (and also, BTW, on the Apple ][), the shift key toggled bit 4 of the character being produced, thus it would turn a 1 (011 0001) into ! (010 0001), and , (010 1100) into < (011 1100). Since the digits 1-9 received consecutive code, so did the characters produced by combining them with the shift key. Shift-7 on those keyboards was apostrophe; the ampersand was shift-6. Other typewriter keyboards also varied considerably in where they put the ampersand. Its association with the number 7 is nowhere near as consistent as the association between 1 and !, 3 and #, 4 and $, or 5 and % which existed in both older computer keyboards and today's US arrangement.

Input: Consider Input: Question: I am creating a computer game in which the character needs to consume food in order to not starve to death. In the game I can display the level of how much food the character currently needs via "hunger level" - the higher this value, the more desperately the character needs food. But what I want now is to turn that around, so that this level tells how full the stomach of the character is. In German we have a word for that, "Sattigung", which means how full my stomach is (or better: how full it feels to me), it is basically the opposite of hunger. Is there a similar word in English, which means exactly that, the opposite of hunger? It might be something like "saturation", but from what I can tell this word is usually used in a technical context, like in "the saturation of a color". Can I use that "saturation" to describe the opposite of hunger of a human or animal, or is there a better word for that? 
Answer: I think the apter word is 'satiety' than 'saturation' in the OP's context. satiety thestateof beingcompletely satisfied,especiallywithfoodor pleasure, so that you could not have any more.

Output: yes


Input: Consider Input: Question: Which is correct? The thief carried the knife carefully so as not to cut himself. The thief carried the knife carefully not to cut himself. 
Answer: The first one. The second one sounds quite awkward, and in fact one way I can think of to improve it would be to add a comma: "The thief carried the knife carefully, not to cut himself". The slight pause is meant to suggest the missing "so as"!.


Output: yes
