Which of the following skills is enhanced by regularly summarizing reading passages?

Regularly summarizing reading passages significantly bolsters verbal reasoning skills. This is primarily because verbal reasoning involves the ability to comprehend and process language, draw inferences, and synthesize information from written text. When a person summarizes a passage, they engage in critical thinking to identify the main ideas, understand the relationships between different parts of the text, and articulate those concepts succinctly.

This skill is essential for effective communication, academic success, and adapting to various contexts that require interpretation and expression of complex information. In contrast, the other skills listed—numerical reasoning, logical reasoning, and spatial reasoning—are more focused on different cognitive abilities that do not primarily rely on the processing and comprehension of text. Therefore, the activity of summarizing reading passages directly enhances one's capacity to think and communicate clearly with language, which is central to verbal reasoning.
