The lifespan of queen angelfish kept in artificial environments is nearly twice as long as those tracked in the wild. researchers hypothesized that the lack of natural predators in artificial environments explains the increase in lifespan. after a series of experiments to create artificial environments containing known predators of queen angelfish, it was discovered that queen angelfish continued to live nearly twice as long. therefore, the exclusion of natural predators does not sufficiently explain the increased lifespan of queen angelfish. Which of the following statements best expresses the main conclusion of the above argument?
O researchers hypothesized that the lack of natural predators in artificial environments explains the increase in lifespan.
O the lifespan of queen angelfish kept in artificial environments is nearly twice as long as those tracked in the wild.
O the exclusion of natural predators does not sufficiently explain the increased lifespan of queen angelfish.
