Generate the answer for a given question. The question requires common knowledge of English. Make sure that the answer is in detail, long, consistent with the context, and requires general knowledge of English. To be less repetitive, please vary your language for each question. Give a proper explanation to answer, and if necessary, provide the definition of various terms. And conclude your answer if it's long. If you have used other resources (e.g., Merriam Webster's.) to answer the question, include citations in your answer. You don't need to paraphrase the context of your resources, but make sure that your answer is consistent and complete.

Input: Consider Input: How should you reply to 'what's up?'.

Output: 'What's up' means 'What's happening.' I usually just reply 'nothing.' because nothing is happening to me. But, there are alternatives, such as the usual reply to a greeting: Not much Nothing. Yourself? I'm good, yourself? Good. How are you? However, if there is something that you would like to tell the other person e.g. You've sold your car, it might go like this: A: What's up? B: I've sold my car. A: Good on you mate!


Input: Consider Input: I was laying in bed or lying in bed?.

Output: According to Google NGrams, 'lying in bed' is much more common. 'To lay' is a transitive verb. It can be reflexive - 'I lay myself', 'I am laying myself', 'I was laying myself' - but it requires an object noun. 'To lie' by contrast is intransitive. It is an indicator of state, not action. Thus, your statement, which indicates your state in the past perfect, should use this verb and not 'lay'. If 'I was laying in bed', the connotation is that I was in the act of laying something in that bed, and the sentence is not proper unless that object is either stated explicitly or inferred by context; it can range from the innocent reflexive ('I was laying myself in bed') to the innocent transitive ('I was laying my infant daughter in bed') to the sexual ('I was laying my girlfriend in bed') to the absurd ('I was laying eggs in bed').


Input: Consider Input: When someone says I stand corrected. What does that mean?.


Output: It means 'I admit that I was wrong'. See e.g. Cambridge Dictionaries: used to admit that something you have said or done was wrong I stand corrected - the date of foundation was 1411, and not 1412 as I had written. Or Wiktionary: Said to acknowledge someone who corrects something that one says or writes that was not correct. The Battle of Hastings was fought in 1056. No it wasn't! Look in the textbook! Oh, sorry. I stand corrected - it was fought in 1066. Note that the Cambridge Dictionary marks this idiom as 'formal', and Merriam-Webster's Learner's Dictionary as 'somewhat formal'.
