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.

[EX Q]: Question: I'm a little bit confused with the following phrase. I was reading an article about concurrency in Java and there was a sentence saying: It is worth noting that both unlockRead() and unlockWrite() calls notifyAll() rather than notify(). This phrase seemed quite strange to me. What does it mean? 
Answer: "It is worth noting that" simply means "here's something, which you should remember:" or "here's something you should pay attention to:" or "here's something that is worth reading and remembering:" It's that simple. Regarding (1), there is no connection at all to "apropos" or "besides..." Regarding (2), it always means exactly the same thing. It simply means "Here's an interesting point:" (There is utterly no connection in any way to "useless" or "costs nothing".) It is worth noting that, the ELL site exists for basic questions about the meanings of phrases.
[EX A]: yes

[EX Q]: Question: What is the plural of syntax? Would it be syntacies? What rule would govern this kind of construction? 
Answer: As FumbleFingers has commented, the plural is syntaxes. That's probably because the normal plural -es is added to the root word, or it may possibly be because the Greek/Late Latin word from which syntax is derived is syntaxis and Greek words ending in -is are pluralised with -es. If we were to create a spoof plural for syntax it would be syntaces (words ending -x get -ces; the preceding vowel can change as in index/indices). But no-one uses that, or would know what it meant.
[EX A]: yes

[EX Q]: Question: "Vomit" is not a recent addition to English, and nor does it have a peculiar pronunciation. Yet, the past tense of vomit does not follow the notion that a vowel followed by a consonant and emphasis on the consonant. (For example, past tense of 'emit' is 'emitted'.) 
Answer: The crucial thing is that the last but one syllable of "vomited" has no stress. Not even secondary stress. So the final consonant doesn't double. By contrast, the last but one syllable of "emitted" has stress (because the last syllable of "emit" has stress). This issue is raised in this question, to which a good answer is given. Compare: (No stress) marketed, budgeted, edited (Secondary stress) combatted, formatted (Primary stress) patted, petted, pitted, potted, rutted.
[EX A]:
yes
