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: In my language, when I write an email to my professor, boss, etc, there is a greeting part in the first part of email right after "Dear prof. ..."(in my language of course), e.g. "How are you", "I hope everything is alright" and so on. But I don't have any idea how can I write a proper email with such a greeting in English? Or do I have to ignore it because the email is kinda formal? 
Answer: I almost always start formal e-mails with Dear Professor _, I hope this note finds you well. Some guidelines will suggest ending your salutation with a colon rather than a comma, but in many circumstances a comma is acceptable. If the person's title is "professor," you should spell it out (not "prof.") and begin it with a capital letter when it precedes the person's name (as it would in your example). "I hope this note (or letter) finds you well" politely establishes a friendly connection between you and the recipient of your letter and in most circumstances is a great way to start it. Especially if you're asking for something, it's good to indicate your concern for the person you're writing to. For the same reason, it's a good idea to end the letter with a phrase or sentence that will similarly show interest in their work or their well-being. "Best regards," is fine, but if you can tailor it in a way that's a bit more thoughtful, it's better. "I hope your book/project continues to go smoothly." (This can be followed by a "Best regards.") If this is a person you don't know, you may have to settle for a generic "Best regards" alone.

[EX Q]: Question: For example In Sim Lim Square cheat cases, a person paid $1k for iPhone insurance. He "agreed" to buy it because the price was not clearly written. In some restaurants, prices are not written clearly and people can then be charged exorbitant prices. Insurance costs can vary by up to 100 times because the cost is simply not written clearly. Many politicians use deceptive language. Also, they tend to tell only the benefits without telling the negatives. Say you are a scientist. You have 10 studies supporting your theory and 90 studies showing you are wrong. You only quote the 10 studies to people that can't expect. All of these are deceptions that would make people choose really really "bad deals". Is there a word to describe such deceptions? Lying? Sophism? Fraud? Scam? Pull a fast one? What? 
Answer: Mislead/misleading One can be misled into thinking something, even if no lies are involved. Doesn't necessarily rule out lying though. The restaurant misled its customers by hiding information about extra charges.
[EX A]: yes

[EX Q]: Question: I saw an article today that prompted a thought. I only took a year of Latin in high school, so I want to run this by some other people. The article referenced a female senator so-and-so. However, I think that senator, with the -or ending is in the nominative, third declension, which is not gender neutral. So, when referring to a female subject, should senatrix be used instead? Also, does anyone know if there is a reason why the male form is used exclusively? I think females were restricted from the Roman senate perhaps the term just never made sense etymologically because of this? 
Answer: The same issue comes up in the word *senile,*and although anile is an English word, it is seldom used. As for the suffix trix, it clings to life in geometry, where a parabola is defined as the locus of points equidistant from a point p and a line L called the directrix. Perhaps one could argue that "directrix" is just a Latin word. I don't think so.
