(单选题)

Which of the following sentences can best fit in the blank in the fourth paragraph? ( )

A.People in less developed countries are more likely to keep others’ wallets.

B.People in higher economic statues are more honest.

C.The more money out in the wallet, the better we can know people’s honesty.

D.With greater temptation, comes greater honesty.

参考答案：D

参考解析：

空缺处前面说有38-40个国家，有现金的钱包归还的概率更高，现金多的钱包归还率更高。所以可以针对这个实验描述得出一个结论，那就是：现金越多、诱惑越大，反而归还率越高。该段并未提及发达国家与不发达国家之间的对比、经济地位高的个体与经济地位低的个体之间的对比，故选项AB直接排除；C项：现金越多，越能测量人们的诚实度，无法与前部分内容形成总结关系；选项D表述更能总结该段前面的内容。故本题正确答案选D。
