问题 What is the passage mainly concerned with?
The word "unwieldy" in the second paragraph is closest in meaning to _______.

选项 A、difficult to collect
B、difficult to tackle
C、incomprehensive
D、uncontrollable

答案B

解析 猜测词义题。通过上下文的含义猜测生词的词义,将四个选项分别放到原句子中去比较也不失为一种好办法。第二段最后一句话“Large masses of data…the properties of un otherwise unwieldy mass of data .”的意思是说,大量的数据群必须要有一个总结或减收的过程,为了从可能是乱七八糟的数据群中找出其特征,关键词是otherwise,表示前后有个对比。 可见后面提及的unwieldy mass of data是难以处理的数据。再看四个选项:A“难以收集”,文章没有提收集;B“难以处理”,与上下文正好相符;C“不可理解的”,前面说将它们整理成容易理解的形式,可见它们还是“可以理解的”;D“不可控制的”,与句意不符。故选B。
