Which of the following is a key element of the Reading Comprehension section?

Understanding narrative structure is indeed a key element of the Reading Comprehension section. This aspect focuses on how a story or text is organized, including the sequence of events, the development of characters, and the overall themes presented. Grasping narrative structure allows readers to follow the logic and flow of a text, which is essential for grasping the main ideas and underlying messages.

In contrast, analyzing numerical data is typically associated with quantitative reasoning rather than reading comprehension, and translating foreign languages requires language proficiency rather than comprehension skills specifically. Summarizing musical compositions involves a different set of skills, focused more on auditory analysis and artistic interpretation than on reading comprehension. Thus, understanding narrative structure directly supports effective reading comprehension, making it the correct choice.
