question:
Question: If you, for example, have to add a person to an application whilst that person is on the phone, how do you politely ask for that person's gender if the voice and/or name has not proven decisive? To clarify why I posted this question on this site: I was looking for an answer within the context of the English language and usage. The given answers have proven that this question really isn't off-topic, other languages know different distinctions that are relevant to addressing this issue. 
Answer: I totally agree that this is not really about English language usage but here's a suggestion anyway...preface the question with an apology, "I'm sorry, but I'm required to ask this question, even if it seems obvious, may I have your gender please?".
answer:
yes


question:
Question: I wrote this sentence: Why wouldn't it be valid? --and I realized that without the contraction it becomes: Why would it not be valid? As opposed to "why would not it be valid," as the contraction would imply. What's going on here? Why can I contract across the middle word this way? Or, to put it the other way, why can't I "de-contract" this without moving the not over by a word? 
Answer: It reflects an older sentence structure of English which is no longer used. You placed the negative immediately after the verb it was negating ('not' placed after 'would'). This structure was used when the contraction first developed. That placement of the negative has changed but is preserved in the contraction.
answer:
no


question:
Question: I am watching a UK TV programme called "The Apprentice". The candidates have to sell guided tours. Some candidates are terrible at giving these tours. They fluff their lines, or they haven't researched, or they make up "facts". Watching their ineptitude cause a feeling of discomfort. What is the best word for this discomfort? The German word schadenfreude means roughly "the pleasure derived from the misfortunes of others". The word I want would be almost an antonym of schadenfreude - "the discomfort derived from the mosfortunes of others". Except not the misfortunes but the uselessness of others. 
Answer: As far as I can imagine, there isn't such a word in the English language, but there are a few words that could be made to fit with that idea. Empathize means sympathizing with another person's unfortunate circumstances. Though empathizing with a person doesn't exactly have to do with that person's ineptitude, you can elaborate on the idea easily enough to make it clear. Empathize means to put yourself in another person's shoes or to feel as another person feels. Pity is another word that is commonly understood but also commonly forgotten. Unfortunately the word pity in modern times has taken on a sort of high and mighty tone that discourages its use, but it means almost exactly what you're trying to express: pity for the person for the embarrassment he or she has brought upon him- or herself. I'm quite positive there are others, but I have a migraine. :) Hope these help!.
answer:

no
