【单选题】What is most probably the key point discussed immediately before this passage


A．Limited time.
B．Making choices.
C．Opportunity cost.
D．The shortage of resources.


网考网参考答案：D
网考网解析：
[解析]推理判断题。文章第一段第一句说We have emphasized so far the significance of scarcity the limited means to satisfy human wants，从so far可以判断前文最有可能是在讲述the significance of scarcity，即原文中的the limited means to satisfy human wants，而means原指“收入。财富，资产”，结合文章最后一段提到的资源分配问题，可判断means在文中指resources，因此答案选[D]。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
