Which aspect of fluency may indicate a risk of comprehension issues?

A low rate of reading is a significant indicator of potential comprehension issues in fluency. When a reader operates at a slow pace, it can signal that they are struggling to process the text effectively, which can impede their ability to grasp the overall meaning of what they are reading. This slow rate might stem from difficulties in word recognition, decoding skills, or even a lack of familiarity with the material, preventing them from engaging fully with the content. In contrast, a higher reading rate is usually associated with greater fluency, enabling readers to focus more on understanding and interpreting the text rather than being bogged down by the mechanics of reading.

Other options presented, such as high accuracy, typically indicate that a reader can read without making many mistakes, which generally facilitates comprehension. Poor prosody, while potentially affecting the emotional expression and natural rhythm of reading, does not directly correlate with the risk of comprehension as significantly as a low reading rate does. Lastly, high vocabulary use suggests a rich understanding of words, which can actually enhance comprehension rather than hinder it. Thus, the low rate of reading stands out as a critical red flag for comprehension difficulties.
