(单选题)

What does the underlined word “It” in paragraph 3 refer to?

A.The new material.

B.The research team.

C.The molecular level.

D.The producing process.

参考答案：A

参考解析：

推理判断题。根据第三段第二句“The team reports the material can be broken down in parts at the molecular level.（研究队说这种材料能被降解成分子大小的微粒）”以及第三句“…can then be built up again to form plastics of different shapes, textures and colors.（然后再次组合形成不同形状，颜色和质地的塑料）”可知，it代指的是前文提到的新材料，尤其从can be和can then be这两个并列句可以推出前后讲的是同物。故选A。
