Correct Response: B. This class could include English language learners at the nonverbal stage of language acquisition to more advanced students whose language proficiency approaches that of their English-proficient peers. Therefore, a varied questioning strategy that allows for differentiation among learners would best promote the oral language development of all learners in the class. A is incorrect because research shows that immediate corrective feedback may interfere with communication and, if used too frequently, can actually inhibit oral language development. C is incorrect because simplifying language forms would not be appropriately challenging input for more advanced learners, while using natural, rapid speech and high-level vocabulary would not provide comprehensible input for less advanced students. D is incorrect because grouping students according to language proficiency level for communicative activities is an ineffective practice, as it does not provide students with exposure to and opportunities to use new vocabulary and more complex language structures.
