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: The B strings tuned w/ low E 7th fret harmonic-(6th string,7th fret). 
Answer: The shorthand w/ is used to mean with. 2 pieces toast w/ gravy Is a shorter way of writing "Two pieces of toast with gravy." The B strings tuned w/ low E 7th fret harmonic-(6th string,7th fret). means "The B strings tuned with low E, 7th fret harmonic . . ." Edited to add: As Denis de Bernardy correctly notes in the comment below, w/o means the opposite: without.

Output: yes


Input: Consider Input: Question: Is it improper to say "me and Person X"? I always hear it said as "Person X and I", but have personally learned to say "me and Person X". Is there a difference between the two versions and is one of them incorrect? "Person and I" just sounds more formal to me. 
Answer: Yes, placing yourself at the beginning is improper grammar. As far as why, I don't know. It just is. To me, it always sounded self-centered to begin a sentence or list of people with myself. I imagine that is the genesis of the rule but I have no idea. It makes someone sound pretty uneducated to do it, though. "Me and Leon" typically followed by "was..." seems pretty common among those with poor grammar.

Output: no


Input: Consider Input: Question: This is similar to a palindrome but, instead of a word/sentence that reads the same forwards and backward, is there a word for words/sentences that read the same right side up and upside-down? See picture below where the word "yeah" is written in cursive: 
Answer: Another answer is symmetric, although that's a broader term. More specific: that it has rotational symmetry. Even more specific: symmetric under a 180 rotation, or it has 180 rotational symmetry. A mathematician might say that it has the symmetries of a parallelogram.


Output: no
