Students are asked to work in groups to explain the advantages and disadvantages of solar power in English. One student, Kevin, understands the scientific concepts but struggles to express his ideas in English independently. During the activity, the teacher provides guiding questions, sentence starters (e.g., "One advantage of solar power is..."), and strategic peer support from a more proficient classmate. By the end of the lesson, Kevin is able to participate successfully in the group discussion and explain his ideas with minimal assistance. Which of the following BEST illustrates Vygotsky's concept of the Zone of Proximal Development (ZPD)?
