To me, the crucial part here is "before you begin" - this means that we're being asked for the steps before you write the first letter.
First, it's good to have a topic (1) for your paragraph - or a leading thought if your paragraph is a part of a bigger piece. This will ensure you stay on this topic and not digress.
Second, it's good to have the content ready (2) - so the arguments and the examples you want to give.
Third, it's good to have a structure(3) - this way your paragraph will be easy to read.
If you have those before you even start writing, your paragraph will be well-structured and well-written!
D) “m” as the two verbs beginning with m - “moan” and “murmuring”
you could also say that it’s “i” with immemorial and innumerable
D. It focuses on the natural world
Some people might say it is even good to mention incomplete projects, It's even better to have something already done. I would say that it would be fine to mention it, might even help.
There’s nothing to answer here sorry
