Pollination syndromes are suites of floral traits that have independently evolved as a result of selection pressure exerted by pollinators; psychophilous (butterfly-pollinated) flowers, for example, frequently exhibit yellow, red, or orange coloring. In a review of previous studies covering 417 plant species, Victor Rosas-Guerrero et al. concluded that the syndromes reliably predict angiosperms’ most effective pollinators. However, in a response paper, Jeff Ollerton et al. note that Rosas-Guerrero et al. may have inadvertently ignored inconsistencies in how authors of previous studies evaluated floral traits.

hardWhat does the text most strongly suggest about the study conducted by Rosas-Guerrero et al.?
A
A limitation in the methodology used by the researchers may entail that the study’s conclusion is not well supported.
B
The approach selected by the researchers enabled them to sort through and remove obviously incomplete or inconsistent data before conducting their analysis.
C
Because the study contained data on a limited number of plant species, its conclusion is accurate for those species but cannot be applied to species not in the study.
D
Due to the difficulty of gathering representative research on angiosperms, the study may have included previous research with a focus too heterogeneous to be comparable.
