This pattern, known as the expertise-reversal effect, suggests that the most effective amount of instructional guidance ______

Detailed worked examples reduce the mental effort required for beginners learning a new skill, but the same level of detailed guidance can become redundant, and even counterproductive, for learners who already have substantial expertise in the subject. Which choice most logically completes the text?

This pattern, known as the expertise-reversal effect, suggests that the most effective amount of instructional guidance ______

Answer and explanation

Answer: D: depends on how much prior knowledge the learner already has.

The passage's key contrast, the same detailed guidance that helps beginners can hurt advanced learners, only makes sense if the right amount of support shifts depending on the learner's existing knowledge, which is D. A contradicts the passage's central point about a reversal occurring between different learner types. C overcorrects into an absolute rule that ignores how the passage says guidance helps beginners specifically. B restricts the finding to one teaching method without any textual basis for that restriction.
