The correct answer is C. The use of camels as transportation
Step-by-step explanation:
In writing, one of the most important factors that determine the topic you select is the number of pages you are allowed to write that is linked to how narrow or broad a topic is. In general terms, it is considered a topic is broad when the author will need to add multiple details, information, and pieces of evidence to develop the topic in a complete way, which usually requires at least 5 or 10 pages but can even require more pages and deals with general topic or events. On the other hand, a topic is considered narrow, when it addresses a specific point of a general topic and requires less than 5 pages to be developed.
Considering this, the topic that would be appropriate for a three-page research paper is "the use of camels as transportation in ww1" because this topic does not address a general events such as the world war one or the impact or effects of some event that would require multiple details, but address a specific point which makes it a narrow topic that can be developed using few details and therefore is appropriate for a three-page research paper.
