M: Do you know anyone who has a spare bookshelf? I just don't know where to put my newly borrowed reference materials.
W: Have you checked with Marsha?
Q: What does the woman suggest the man do?
正確答案：D
解析：通過問句Have you checked with Marsha?來提出建議。不過這個建議題難度稍大些，要求考生不但要聽懂建議句，而且要抓聽到原問句中的關鍵信息spare bookshelf“多余的書架”，否則還是有可能錯選。正確選項中的extra bookshelf是原文中spare bookshelf的同義替換。
