Explanation:
I could not find the excerpt that is missing but I will tell you something about central idea in the literature that may help you in your research.
The central idea can be found in every story and it is representing the main key and element of it. The central idea should tie all element in one to prove the main and dominant impression of the story.
Central idea is also known as the main idea and it is proving the main and central point of the excerpt or the whole text.
You can find the central idea often in the first sentence and also in the last one.
