SAT test writers have become very interested in economist Giulia Faggio’s study of the factors that influence industrial agglomeration. In simple words, agglomeration is the clustering of firms in a specific location. For example, in the early twentieth century the automobile industry concentrated in Detroit. Today, Apple and other high-tech computer and chip companies are concentrated in Silicon Valley south of San Francisco.
OK, but what does this have to do with the appearance of AMASS as the answer to several recent vocabulary in context questions? AMASS means to gather in one place, So, AMASS is an SAT way of saying that related industries tend to concentrate or gather in the same geographic location. I told you this would be easy!
AMASS – to gather together; collect or concentrate in the same location
