In my head it does not make a lot of sense cause you are assuming that the review was blind because it is a "well regarded
OFFICIAL EXPLANATIONInference(1) The information regarding the sometimes dysfunctional social dynamics of research groups is not sufficient to show that research groups with such experiences always fail to produce successful research outcomes. So the information given here is not sufficient alone to indicate a yes or a no answer to the question posed; NOT sufficient.
(2) The information gives us an example of one interdisciplinary collaboration on research that reported in a blind peer-reviewed publication its review of research studies on urban greening. The review found that there was insufficient evidence to show that planting trees in urban areas had a significant impact on air quality in such areas. Even though the result of its review was negative, its review of scientific publications on the issue was approved in a blind peer review and published. Therefore (2), in combination with the stimulus information, is sufficient to provide at least one example of a successful outcome of an interdisciplinary research project. This, in turn, is sufficient to show that interdisciplinary research groups
can produce a successful outcome; SUFFICIENT.
The correct answer is B; statement 2 alone is sufficient.
