Text 1Starfish, echinoderms belonging to the class Asteroidea, have a nervous system composed of individual nerves grouped into a structure called a ganglion. However, they do not have a defined central nervous system. Consequently, biologists believe that they pick up only limited sensory information from their surroundings and that most of their behavior is guided by their sense of smell.Text 2Since 2015, several studies of starfish behavior have indicated that contrary to prior hypotheses, most members of Asteroidea possess a range of senses. While little is known about the physiology behind these mechanisms, available data indicates that starfish possess a sense of touch in addition to their sense of smell. Some can sense gravity, and many can sense the direction of currents. Additionally, most species have eyes that play a prominent role in locating feeding grounds. While more study is needed, most researchers now believe many senses govern starfish behavior.Based on the texts, what would the author of Text 2 most likely say about Text 1’s characterization of Asteroidea’s sensory capabilities?The nervous systems of starfish are not complex enough to support the processing of sensory information.eliminateThe assertion that starfish rely mainly on smell is an oversimplification based on outdated assumptions.eliminateStarfish lack the organs necessary to gain sensory information from their surroundings.eliminateWhile starfish possess a sense of smell, this particular sense is unlikely to influence their behaviors.
