coverage, angles, tones, opinions, accuracy and so on.
Write a paragraph about each of these. You can show both similarities and differences. You might use a paragraph to write about the "tone" used in all three newspapers and include examples. Actually, that might require several paragraphs.
Okay... I know what to do... I hope the prof allows you to use section headings. Make each of those words into a section heading, and in each section write one paragraph about each idea you want to share. This complex paper will need a lot of section headings! Use the headings to show that prof that you definitely are thoroughly following the instructions.
Then, you'll need section headings that show various observations you make about their coverage of the flood. What is the main idea you get when you compare their coverage of it? Make that into a section heading.
I hope that helps!! The key is to keep it simple and thorough and clear by using section headings. Do one at a time. You can probably write a few paragraphs about the sims and differences in tone easily, right now, for example, right? Just do the section on similarities and differences in tone. Write a few paragraphs about it...
