(单选题)

What do we know from paragraph 3?

A.Teenagers should go home to eat meals.

B.Parents should play a part in improving food safety.

C.Food safety problems can be easily solved.

D.Parents are angry about food safety.

参考答案：B

参考解析：

推理判断题。根据第三段第一句“The regulation also suggests that parents should eat with students at school in order to provide advice on food safety and nutrition.”可知，该规定还建议家长应与在校学生一起吃饭，以便就食品安全和营养提供建议。可以推测，这一段要求家长应该在改善学校食品安全方面发挥作用。故选B。
