Step-by-step explanation:
A summary is a shortened version of a piece of writing (a paragraph, chapter, entire story, article, etc). It should include only the main ideas and the most supporting important details of the text.
The main idea is the main point the author of a text is making. Supporting details are pieces of information that illustrate, describe, explain, expand, or clarify the main idea.
The main idea of the given passage is that Rio is a popular tourist attraction that attracts many tourists with its festivals and significant events it hosts. This is why statement C should be included in the passage. Every other statement is true, but they are supporting details, which means that they don't need to be included in the summary.
