Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no".

Input: Consider Input: Question: This question comes from a quiz but I could not find the correct answer. 
Answer: The indefinite determiner "a" represents all things in a given category rather than the more specific definite determiner "the". So, if you were to ask me, "Every Hiker climbed a hill" represents a specific group of hikers who climbed non-specific hills and not the same hill. If the sentence said, If every hiker had climbed the hill, it would be only one hill.

Output: no


Input: Consider Input: Question: Everybody deals with this phenomenon daily but I had my curiousity piqued when someone claimed that punishing the many for the actions of the few was just called "group punishment." Group Punishment is simply punishing a large group of people. Is there a specific word for when a large group is punished because of the actions of the few? Such as in the following: Little Jimmy wasn't happy when the entire class was forced to work through recess because of 3 kids getting into a fight yesterday. 
Answer: Collective punishment is the formal expression: Penalty imposed on every member of a group without regard to his or her involvement in the group's actions and conduct. Related: collective responsibility. (www.businessdictionary.com) Is collective punishment fair in the classroom?: Under the 1949 Geneva Conventions collective punishment is considered a war crime. "No general penalty, pecuniary or otherwise, shall be inflicted upon the population on account of the acts of individuals for which they cannot be regarded as jointly and severally responsible." Unfortunately for our students they do not have rights as general citizens or even our war enemies and common criminals in society. They shed their rights as they enter the double doors of the school and us parents shed our ability to ask for fair treatment of our children.

Output: yes


Input: Consider Input: Question: Possible Duplicate: Do you use "a" or "an" before acronyms? Does one use 'a' or 'an' before the word 'X-Ray'? Quite simply, should a sentence read "a XML report" or "an XML report"? 
Answer: It's "an XML report", because which form of the indefinite article to use is decided by how the next word is pronounced. In this case, it's pronounced: An ex-emm-ell report 'XML' begins with a vowel sound, 'e', so an is used rather than a.


Output: yes
