问题 What is the primary purpose of this passage?
This passage is most probably an excerpt from ______.

选项 A、a scientific journal which introduces the latest development in oceanography
B、a popular magazine that explains new ideas to interested readers
C、an introduction to a book on oceanography
D、a textbook for pupils

答案A

解析 B选项的范围太宽。D选项不尽合适，因为这样的文章给小学生看太过深奥。C选项最有干扰性，但一般在介绍部分的内容都应是公认正确的理论，或是全书要详加阐述的内容，本文不符合这两个要求。比较起来A选项最恰当。
