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: What's the difference between transparent and translucent? I am trying to describe this record pressing. 
Answer: Technically speaking translucent is semi-transparent. As simple as that. But translucent is only a technical term while transparent may be used figuratively i.e. something which is evident, clearly seen or understood. "Transparent policy, accounting etc.".

Output: no


Input: Consider Input: Question: A few days ago, a friend and I were discussing how every "rule" of English spelling or pronunciation has an exception, and every exception has an exception as well. Then I brought up the rule of a ph cluster equaling an f sound (as in phonetic, elephant, morph, etc.) as a pronunciation rule that didn't have any exceptions I could think of. Is this a true hard-and-fast rule or does it have some exceptions as well? I'm not counting abbreviations such as pH scale. 
Answer: The exceptions come in two categories: Greek words that were originally pronounced with an "f" diphtheria, diphthong, ophthalmology, phthisis but have come to be pronounced with a "p" by no process I understand. Compound words uphold, saphead, peephole that are just a word ending in "p" run up against a word beginning with an "h". Neither of those really feel like exceptions: mispronunciations that have become accepted and two words being treated as one. Then there is aphelion. Arguably, that's a compound word and a mistake. By analogy with apogee and apastron, it should be apohelion: "apo" ("from") + "helion" ("sun"). Several people brought up "Stephen", which is often pronounced like "Steven". Eh, I think we should play with Scrabble rules: no proper names. Finally, there is an example that will really blow your minds: phthalate. The ph- is silent.

Output: yes


Input: Consider Input: Question: I debated with my peers that we can use the word emails when referring to more than one and it would be grammatically right. But most of them said since we don't say we received mails today, similarly we won't say we received emails . Quick advice please. 
Answer: Emails and email are both correct plurals, but each has its own context. It depends on whether or not you are using it as a countable or uncountable noun. Email You can use email as an uncountable noun, just like mail. For example, "I received lots of email today" or "John sends me too much stupid chain email". But, you cannot use email as a countable noun. For example, "I have five email" makes as much sense as "I have five mail". Emails You can use emails as a countable noun, just like letters. Originally, email was always uncountable, just like mail. But over time, largely due to the ubiquity of use, pieces of email or email messages (and similar phrases) were shortened, and simplified to just emails. For example: "I have five emails" or "Kevin sends me too many emails". (Contrast that last one with "Kevin sends me too much email".) Of course, you can still use emails in some contexts where email is also acceptable ("I received lots of emails today"), but it does have a slightly different meaning (compare to "I received lots of email messages today") because you are using a countable versus uncountable noun.


Output: yes
