问题 Which of the following statements is CORRECT?
What is the main purpose of the passage?

选项 A、To outline the research findings on the brain structure.
B、To explain the link between sex and brain structure.
C、To discuss the various factors that cause brain differences.
D、To suggest new areas in brain research.

答案B

解析此题为一般推理题。全文的主题涉及男女大脑机理是否存在差异以及生物学家的相关研究结果。研究表明，男女在大脑结构上存在差异，但这种差异是否导致男女在一些技能上的差异还不得而知。A没有涉及男女差异问题，不妥；全文没有讨论导致大脑差别的不同因素，故排除C；文章结尾虽然提及将来需要研究的一个问题，但这不是全文的主旨。
