Answers that are not definite and suggest a variety of options are not acceptable answers.

[EX Q]: Question: Is there a specific reason for this? After all, it is "boys and girls", rather than "girls and boys". If the boy (male) comes first here, why doesn't it come first in "ladies and gentlemen"? 
Answer: It comes from "My Lords, Ladies and Gentlemen". Titled men come first (My Lords); then their spouses [My] Ladies; Ladies also include non-titled ladies; and finally, untitled men (Gentlemen).

[EX Q]: Question: When should whilst be used instead of while? For example, should I use the first or the second sentence? They don't do this whilst they do that. They don't do this while they do that. Which would be correct? 
Answer: I believe while and whilst are interchangeable, but whilst is more archaic and adds a nice flavoring to the sentence. That being said, "whilst" doesn't seem to come up so often in the middle of a sentence as you had it there, so I would use "while" in that case, even though both are grammatically correct. Whilst seems more apt to be put at the beginnings of sentences, e.g. Whilst going about my merry way I chanced upon a vagabond. Taking this serendipitous opportunity to satiate my bloodlust I decapitated him with a fork.
[EX A]: yes

[EX Q]: Question: Possible Duplicate: This question has been asked at/on SO? Which sentence is grammatically correct? The papers are freely available at the journal website. The papers are freely available on the journal website. Using Google's search results: available at the website returns 72,800,000 results. available on the website returns 106,000,000 results. So, I inferred that both variants are popular. Is this method (comparing the number of results by Googling) sound? 
Answer: Speaking as a longtime computer geek, files are said to reside on a hard drive or on a certain machine. Since I know that a website is made of computer files, I think of a website as being on a machine and so any part of the website is also on that machine. A website's "address" is a "Uniform Resource Locator" or URL. These terms connote the idea of website as "place". In this case the file would be at the website location. So, if you think of a website as it is actually constructed (files stored on hard drives), you will probably say on. If you think in the location metaphor, you will probably say at. Personally I find myself saying "on" to other geeks and falling into "at" when speaking with normal people.
