问题 Scientific research that involves international collaboration has produced papers of greater influence, as measured by the number of times a paper is cited in subsequent papers, than has research without any collaboration. Papers that result from international collaboration are cited an average of seven times, whereas papers with single authors are cited only three times on average. This difference shows that research projects conducted by international research teams are of greater importance than those conducted by single researchers. Which one of the following is an assumption on which the argument depends?
选项 A、Prolific writers can inflate the number of citations they receive by citing themselves in subsequent papers.
B、It is possible to ascertain whether or not a paper is the product of international collaboration by determining the number of citations it has received.
C、The number of citations a paper receives is a measure of the importance of the research it reports.
D、The collaborative efforts of scientists who are citizens of the same country do not produce papers that are as important as papers that are produced by international collaboration.
E、International research teams tend to be more generously funded than are single researchers.
答案C
解析 本题根据国际研究发表的论文被引用的次数较多，做出了国际研究项目的重要性较强的结论，因此作者结论所依赖的假设很明显就是一篇论文被引用的次数是它所报道的研究项目的重要性的标准，也即(C)是正确答案；(A)、(B)、(D)和(E)四选项均不能从本题的论证中推出。
