Stimulus

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 research teams are of greater importance than those conducted by single researchers.

What this question is testing

Necessary Assumption

Your task

Find the assumption the argument requires in order for its conclusion to hold.

Common trap

Answers that would help the argument but aren't strictly required (sufficient, not necessary).

Winning move

Negate each choice — the right one breaks the argument when negated.

Answer choices

  1. Out of Scope: Prolific Writers0% picked this

    Prolific writers can inflate the number of citations they receive by citing themselves

    Prolific writers can inflate the number of citations they receive by citing themselves in subsequent papers. While self-citations can affect citation counts, the argument does not specifically address the authors' behavior in citing their own work. This choice is more about the mechanics of citation counts rather than whether citation count equates to research importance.

  2. Irrelevant to the Conclusion: Citation Identification8% picked this

    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. The argument does not claim that you can identify collaboration from citation counts; it only argues about the relative importance (influence) based on those counts. So, establishing collaboration through citation count isn't necessary for the argument.

    Why this is right

    The number of citations a paper receives is a measure of the importance of the research it reports. This assumption is essential for the argument because it directly ties the number of citations to the importance of the research. If we negate this assumption and say that the number of citations does not measure a paper's importance, then the entire argument falls apart. The author would have no basis for claiming that internationally collaborative research is more important based solely on citation counts.

  4. Out of Scope: Domestic Collaboration6% picked this

    The collaborative efforts of scientists who are citizens of the same country do not produce papers that are as important as papers

    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. While this might be an interesting comparison, it's not necessary for this argument specifically, which is about single researchers versus international collaboration. The argument does not need to make comparative claims about same-country collaborations.

  5. Out of Scope: Funding Levels0% picked this

    International research teams tend to be more generously funded than are

    International research teams tend to be more generously funded than are single researchers. Although funding might play a role in the ability to conduct research, the argument does not hinge on funding differences but rather on the assumption that citations equate to importance. Thus, funding levels are not directly relevant to the argument's core assumption.
