It can be inferred that the author would most likely agree with which of the following assessments of the results from field studies A. Many of the results contradicted predictions of susceptibility to invasion that are based on the availability of resources unused by the community. B. If fluctuating resource availability were taken into account, many of the apparent inconsistencies among the results could be explained. C. The apparent inconsistencies and ambiguities in the results are caused by trying to make them fit an inadequate general theory of invasibility. D. No general theory of invasibility has emerged because none of the studies has been able to assess the degree of an invasion accurately. E. The results tend to show a degree of susceptibility to invasion that is lower than would be expected given the prevalence in the wild of nonnative species.
