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.

Example Input: Question: On a Physics specification, it says: 6.7 Know how to use two permanent magnets to produce a uniform magnetic field pattern. Isn't it "produce an uniform magnetic field", or is the existing "produce a uniform magnetic field pattern" correct? 
Answer: The word uniform begins with a palatal approximant /j/. The palatal approximant is a consonantal sound, even though the letter itself is a vowel. Since we use the pronunciation of the word following the article to determine whether we use "a" or "an", and because it is pronounced starting with a consonant, we use "a". Thus, the original sentence is correct. Just for the sake of completeness, the letter "u" can also have a vowel sound, such as in the word "umbrella", which begins with an open-mid back unrounded vowel //.
Example Output: yes

Example 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.
Example Output: no
