Which of the following statements best explains the effect fluency has on reading comprehension?

While fluency is a significant factor in reading comprehension, mastery alone does not guarantee understanding. Comprehension also depends on background knowledge, vocabulary, and engagement with the text. Thus, simply being fluent does not ensure that a student can easily grasp all texts without considering these other components.

This statement incorrectly suggests that reading below a student's level necessarily leads to decreased fluency. In fact, students may exhibit higher fluency with easier texts, which could potentially enhance their comprehension. The relationship between text difficulty and fluency is more complex and does not universally imply a negative effect on comprehension.

While there may be some correlation between fluency and comprehension, assessing fluency alone does not provide a complete picture of comprehension skills. Comprehension requires evaluating how well a student understands and interprets the text, which cannot be fully determined by fluency assessments.
