Answer:
A
Explanation: Its not focused on one movie. Teachers find that kids doing history related stuff get better grades because of this. Silent films are also very easy to research.
C should be the answer. A doesn't help you organize information, because it's "random" labeling. B includes paragraphs, which you usually don't construct in an outline bc outlines are brief. for D, it's a research paper and one can assume that all information is fairly relevant and important, plus color coding isn't a typical part of an outline. E says to list it alphabetically but that doesn't help you organize your information either because you don't necessarily want your research papers to be alphabetical, you want them to follow a logical path.
Archaeology, Arterial, Astrophysics, Authenticity, Autobiographical, Axiom
The correct way to write this sentence is as follows,
Yellow Stone National Park, the west oldest national park is the site of Old Faithful.
You have to capitalize Yellow Stone National Park and Old Faithful because they are proper nouns.
Hope this helps. :)
