As a general answer (not one relating necessarily to the questions to which you've referred):
If I am writing a question and do not know how to phrase a particular passage, I:
- Look in my textbook to see if it refers to something similar. I might be able to copy the wording.
- Look at the "suggested duplicates" and "related questions" on the "Ask new question" page. It is possible they may refer to something similar.
- As a last resort, I would go ahead and post the question. Then, I might wonder over to the Chatroom; if I see someone I know (meaning, I've had a conversation in the past with them), I may ask (politely) if they know of a better way of phrasing a particular part of the question.
To generalize further at the risk of going off-topic: The above is representative of (what I believe to be) a good question-asking process. First, see if you can discover the answer yourself from your "given" resources (e.g. from textbooks). Second, see if you can discover the answer from other inanimate resources (e.g. from other textbooks and/or websites). Finally, as a last resort, ask a person for help. I say "as a last resort" because I don't want to waste anyone's time if I could figure out the answer myself.
