    assess students’ skill levels

    B

    respond to individual student’s needs

    C

    deal with students who misbehave

    D

    正确答案： D
    解析：
    细节题。题干问的是“虚拟现实可以帮助未来的教师学到什么”。原文第三段最后一句说到：And it is expected that future teachers will be exposed to virtual classes, complete with “difficult students” to help them master behavior management techniques.由此可知，“difficult students”指的是“调皮捣蛋的学生”，因此C选项正确。A选项的“如何评估学生的技能水平”和B选项的“如何满足个体学生的需求”在文中均没有提到；D选项“如何使教室有秩序(地进行教学)”与文中第三段中“with behavior disorders”不符，也可排除。因此本题的正确答案为C。
