题目原文：
讨论冠恐鸟Gastornis是不是食肉鸟类。
听力材料：
1. It resembles both meat-eating and plant-eating birds so the appearance cannot determine it's a carnivore. Eg. It has the same feature as the ostriches and emus.
2. It has a straight beak instead of curved beak. The straight beak is more likely to be used on plants such as nuts.
3. The foot prints left by Gastornis don't show claws. The last bone of its foot maybe the structure, not a talon.
