<span>utilizing the power of environment</span>
I would have to read the paragraph to give you a proper answer. Could you perhaps take a picture of the paragraph so I may read it?
C. The main idea is the primary point of a piece of writing :)
A shift in thought can be indicated by what is called an em dash. An em dash is used to set of an interruption that is closely relevant to
the sentence but is not grammatically part of it. These set of
interruptions can be found in a list, illustration, restatement, shift
in thought or tone, summary, or dramatic point.
Hope this helps, if you need anymore help or further explanation just let me know!! :)
