Dear instructor, I have a questions about this problem, see second paragraph:
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.
The problem asks "The passage suggests which of the following about the empirical study of small firms' role?". I think "empirical study" refers to "empirical knowledge ", so I tried to find the answer in the first sentence (the bold part).
The second sentence talks about "An additional difficulty...", but it doesn't mention from what kind of study it comes. Do we just assume it is also a part "empirical knowledge"? Or we should decide their relationship by common sense?
For example, if we see following structure:
The ABC study suggests that difficulty A... . In addition, difficulty B...
Can we regard difficulty B as part of the ABC study just because the sentence mentioned "difficulty B" is following the first sentence. Or we have to look at the details of A and B then make our own judgement by common sense.
