This question is incomplete because you are missing part of it; here is the complete question:
Indicate the appropriateness of the subject for a four- to six-page research paper by answering the following question.
Is the following topic suitable for a research paper? Why or why not? how a cheetah eats its food
A. No, it is too broad.
B. No, it is too narrow.
C. Yes, it is broad enough.
D. Yes, it is narrow enough.
The answer to this question is B. No, it is too narrow
Step-by-step explanation:
In a research paper, especially in one of four to six pages, you are required to provide multiple ideas from different sources to explain the main topic. This implies the topic is appropriate only if it requires the author to give many details or can develop it in 4 to 6 pages. This does not occur if you write about "how a cheetah eats its food" because it is likely cheetahs have only one or few ways to eat their food, and therefore this topic does not require multiple details. According to this, the topic is not suitable because it requires few details or ideas, thus, the reason that makes it inappropriate is that is too narrow.
