When the author writes that Chilesaurus diegosuarezi “should have been a meat-eater,” she most likely means that the species:

Rationale

Chilesaurus diegosuarezi had body features similar to those of its meat-eating relative.

The phrase indicates that the author is referring to the anatomical characteristics of Chilesaurus diegosuarezi that align it more closely with carnivorous dinosaurs, despite its actual dietary habits.

A (would have been healthier if it had eaten meat) YOUR ANSWER

This option suggests a health benefit from a meat-based diet, which is not the focus of the author’s statement. The passage does not discuss health implications or nutritional advantages, but rather anatomical similarities.

B (would have grown even larger if it had eaten meat) YOUR ANSWER

While it is possible that a meat-based diet could influence growth, the author's statement does not imply that diet directly correlates with size. The emphasis is on the animal's physical traits, not its growth potential related to diet.

C (had the head, neck, and teeth of a meat-eater) YOUR ANSWER

This choice incorrectly narrows the focus to specific body parts like the head, neck, and teeth. Although these features may suggest carnivorous traits, the statement highlights overall body features rather than isolating particular anatomical aspects.

D (had body features similar to those of its meat-eating relative) CORRECT

This is the most accurate interpretation as it encompasses the broader set of physical characteristics linking Chilesaurus diegosuarezi to meat-eating dinosaurs. The author suggests that its overall morphology aligns more with carnivorous relatives.

Conclusion

The statement about Chilesaurus diegosuarezi emphasizes the dinosaur's anatomical similarities to meat-eating relatives rather than implications about diet or health. By highlighting these shared features, the author conveys the idea that Chilesaurus diegosuarezi, despite its herbivorous habits, possesses physical traits that are characteristic of carnivorous species, prompting the reader to consider evolutionary relationships among dinosaurs.
