Correct Response: C. The Cognitive Academic Language Learning Approach (CALLA) emphasizes explicit instruction in learning strategies (i.e., metacognitive, cognitive, and social-affective) in addition to promoting language development alongside content instruction. This approach works well for English language learners who have already developed social English language skills, such as the developing- and expanding-level English language learners in this scenario. In CALLA, content topics are introduced gradually and initially emphasize those that have extensive contextual supports and/or reduced language demands, making science an ideal area of the curriculum with which to begin. A and B are incorrect because the language of science is neither more complex and abstract nor more universal than the language of other content areas. Conversely, the language of science is not less academic than the language of other content areas, making D incorrect as well.
