Answer:
Although Miep Gies never considered herself a hero, after the war, many other people did.
Step-by-step explanation:
The central idea (also called the main idea or key idea) of a piece of writing is the main point the author is making. The statement that best summarizes the central idea of the given excerpt is the third one: Although Miep Gies never considered herself a hero, after the war, many other people did.
The passage begins and ends by telling us that Miep Gies didn't like being called a hero. When determining what the paragraph is about, we should pay attention to both the first and last sentences. The first sentence is called the topic sentence, and the last is the concluding sentence. Both of them summarize the content of the paragraph.
The rest of the statements are examples of supporting details - pieces of information that explain, describe, illuminate, expand, or clarify the central idea. They tell about Miep Gies' accomplishments, explaining why many people considered her a hero, despite her insisting that she wasn't one.
This is why the third option is the correct one.
