Is this some book? if so i do not undertand
I think the correct word would be meanwhile because the second point is something unrelated to the first point, but the two points are happening at the same time. all the other words in fact, obviously, and besides are used when the point relates to the previous point. hope this helps!
Answer:
A summary begins with an introductory sentence that states the text's title, author and main point of the text as you see it. A summary is written in your own words. A summary contains only the ideas of the original text. Do not insert any of your own opinions, interpretations, deductions or comments into a summary.
