The view has prevailed for the better part of the twentieth century that small firms do not perform an important role in Western economies. Official policies in many countries have favored large units of production because there were strong reasons to believe that large firms were superior to small firms in virtually every aspect of economic performance--productivity, technological progress, and job security and compensation. However, in the 1970s, evidence began to suggest that small firms in some countries were outperforming their larger counterparts. Perhaps the best example of this trend was in the steel industry, where new firms entered the market in the form of "mini-mills," and small-firm employment expanded, while many large companies shut down plants and reduced employment. Although no systematic evidence exists to determine unequivocally whether smaller units of production are as efficient as large firms or are, in fact, more efficient, some researchers have concluded that the accumulated evidence to date indicates that small firms are at least not burdened with an inherent size disadvantage. Thus, an alternative view has emerged in the economics literature, arguing that small firms make several important contributions to industrial markets. First, small firms are often the source of the kind of innovative activity that leads to technological change. Small firms generate market turbulence that creates additional dimensions of competition, and they also promote international competition through newly created niches. Finally, small firms in recent years have generated the preponderant share of new jobs. However, empirical knowledge about the relative roles of large and small firms is generally based upon anecdotal evidence and case studies, and such evidence has proved inadequate to answer major questions concerning the role of small firms across various industries and nations. An additional difficulty is that it is not obvious what criteria one should use to distinguish small firms from large ones. While a "small firm" is often defined as an enterprise with fewer than 500 employees, research studies of small firms use a wide variety of definitions. Question #29.
Question #29. The passage suggests which of the following about the empirical study of small firms' role? (A) Anecdotal evidence does not support the theory that small firms' role is significant. (B) Degrees of market turbulence are the primary indicator of small firms' role. (C) An examination of new niches created by small firms has provided important data for the analysis of such firms' role. (D) Case studies have provided reliable evidence to answer major questions concerning small firms' role. (E) A more precise definition of the term "small firm" is crucial to making a conclusive analysis about small firms' role.
答案是E。 不知道题目里的empirical跟最后一段第一句里的是不是指的同一个东东。如果是，那就只有头句话跟它相关。答案说到的是该段最后一句话，细节题定位不是错了么？
