Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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.
Solution: yes
Reason: The answer is well in context with the question and gives a proper explanation to resolve it. Hence, the output "yes" is correct.

Now, solve this instance: 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.
