Correct Response: D. The fundamental purpose of the unit described in the scenario is to demonstrate the importance of reading in a range of situations that are likely to be meaningful to the students, thus promoting their intrinsic motivation to learn to read well. A is incorrect because the scenario does not provide information regarding the students' favorite social activities, plus the example activities given also focus on practical purposes for reading, such as to enhance safety and manage time. B is incorrect because the unit described does not focus on topics to read about but rather reasons for engaging in reading. Lastly, the unit described does not focus exclusively on in-school reading or on reading resources within the school setting, making C incorrect.
