Question

the following text is about when scientist susan hendrickson found a tyrannosaurus rex skeleton in south dakota. select the best detail to show a dinosaur’s bones can tell you about its diet.

susan . . . saw three huge backbones, a rib bone, and a leg bone. because the broken edges of the bones were sticking straight out of the cliff, susan could tell there were more bones inside. . . .

susan looked closely at the bones. they were hollow. dinosaurs that ate meat, called carnivores, had hollow bones. plant - eating dinosaurs, called herbivores, didn’t. so this was a carnivore. and these bones were huge. \i knew the only large carnivorous dinosaur that lived in that area was the tyrannosaurus rex,\ says susan. \and i thought, wow!\

Explanation:

To determine the detail showing how a dinosaur’s bones relate to its diet, we analyze the text. The first part describes finding bones, while the second part (about hollow bones) explains that carnivores (meat - eaters) have hollow bones and herbivores (plant - eaters) do not. This directly connects bone structure (hollow bones) to diet (carnivore). The relevant detail is: "Susan looked closely at the bones. They were hollow. Dinosaurs that ate meat, called carnivores, had hollow bones. Plant - eating dinosaurs, called herbivores, didn't."

Answer:

Susan looked closely at the bones. They were hollow. Dinosaurs that ate meat, called carnivores, had hollow bones. Plant - eating dinosaurs, called herbivores, didn't.
