Correct Response: B: A think-aloud strategy allows the SEI teacher to model his or her own thinking while reading a complex information text. It provides the opportunity for the teacher to model important reading comprehension strategies, such as independent vocabulary-learning strategies and how to deconstruct complex sentences. In this scenario, the teacher also purposefully selects texts on a wide range of content-specific topics, thus building the English learners' background knowledge related to the health discipline. A and C are incorrect because they focus on concepts and skills related to writing that are not typically part of a think-aloud strategy. D focuses on teaching students about the use of text structure as a comprehension strategy, which does not relate to the teacher's actions in the scenario.
