I see close votes and downvotes on my last question. Is it not allowed to ask here?
You have asked too many questions about your paragraph. That makes the issue too localized to your case. In Stack Exchange, we often try to build a library of information that will aid future learners who stumble upon that question. That changes the site's purpose from a normal helpdesk, where you'd be able to get one-on-one help from an expert. Thus, we close posts that ask too many questions at once, because they're often useful to a single person but never anyone else in the future. This is not restricted to ELL Stack Exchange and is a Stack Exchange policy in general.
What I recommend is you pick the issue that confuses you most, and ask about that. Delete the other questions, or ask them in a separate thread. I don't recommend the latter course of action, because a lot of questions in a short time period about the same paragraph get repetitive and make people frown. Instead, you can probably find a lot of your answers by searching around a little.
