Critical Reasoning (CR) | ­Conservationists have begun removing plant species believed to be

­Conservationists have begun removing plant species believed to be nonnative, or introduced through human contact, from the Galápagos Islands to restore the islands’ ecosystem. But some of these species may be native after all. Humans first reached the Galápagos in 1535, but fossilized pollen grains of several species thought to be nonnative were found in sediment cores over 8,000 years old. Among these species is swamp hibiscus. This plant is spreading, which was taken as evidence of its invasiveness, but scientists now hypothesize that it is reclaiming habitat that was lost over time.

Which of the following would it be most useful to establish in order to evaluate the scientists’ hypothesis that swamp hibiscus is reclaiming habitat?

A. Whether swamp hibiscus provides food for any animal species native to the Galápagos

B. Whether swamp hibiscus found elsewhere is directly related to that growing in the Galápagos
