A US report predicts that in 15 years time the economy in Asia will be larger than of North America and Europe combined.

A. what

B. that

C. one

D. those

答案：

A. what

(答案→)B. that

C. one

D. those

解析：B 考察代词用法。句意：—一份美国的报告预测，在未来的里，亚洲的经济会比北美和欧洲经济的总和还要大。That指代上文提及的同类不同物；one表示一个，泛指；those是指代上文提到的同类不同物的复数概念。由语境可知，本题空格处指代的是economy，故B正确。
