Correct Response: B. Many factors contribute to reading comprehension. Skilled readers use different comprehension strategies to achieve different purposes. For example, the first student described in this item may have skimmed the chapter to look for specific words or phrases mentioned in the comprehension questions, while the second student may have scanned the chapter for main ideas but did not dwell on individual terms or facts. Option A is incorrect because the first student had difficulty answering questions about the gist of the chapter, so it is likely that that student did not apply metacognitive strategies to enhance understanding during reading. Option C is incorrect because the second student was able to construct a strong summary of the chapter, which suggests an ability to use inferential skills. While background knowledge and experiences have a strong influence on reading comprehension (D), this factor cannot explain why the students focused on such different levels of the text.
