Correct Response: C. In a sheltered English immersion (SEI) content lesson, language objectives relate specifically to the content objectives of the lesson. They seek to integrate instruction in vocabulary development and oracy, reading, and writing to support English language learners' ability to achieve the content objectives of the lesson. A and D are incorrect because they only relate to the content objectives and not to the development of relevant language objectives. B is incorrect because it focuses on possible strategies for implementing an SEI lesson but does not contribute information that would be helpful in developing the lesson's language objectives.
