What is meant by vocabulary range?

Vocabulary range refers to the diversity of words a person is able to use and understand, which is essential for effective communication and academic success. In the context of college readiness, a broad vocabulary range allows students to express their thoughts more clearly and comprehend complex texts across various subjects. This ability is crucial not just for casual conversation, but also for engaging with literature, writing essays, and participating in discussions at an advanced academic level.

While the total number of words a person knows is an important aspect of vocabulary, it does not fully capture how those words are varied and utilized in context. Additionally, spelling complex words accurately relates to writing skills rather than vocabulary range. Measuring reading speed pertains to how quickly someone can read rather than their vocabulary's diversity. Therefore, the correct answer emphasizes the importance of having a wide-ranging vocabulary that aids in comprehensive learning and effective communication in academic settings.
