Final answer:
Using percent correct to assess reading ability imposes an inflexible ceiling on measuring a student's performance, not reflecting the full range of abilities.
Step-by-step explanation:
The question addresses how using percent correct to assess a student's reading ability might impose limitations, as it suggests an inflexible criterion in evaluating performance. Using percent correct as the sole measure doesn't consider the depth of comprehension or the level of difficulty of the material being read, thus creating a ceiling effect where the evaluation does not reflect the full range of a student's abilities. This inflexibility could fail to distinguish between students at higher levels of performance, as the assessment does not scale beyond a certain point. The multiple-choice options given do not have a correct answer that is obviously pertinent to the consequences of an artificial ceiling, therefore 'd. none of the above' is the selection that matches the content provided.
