Reading the passage
Walking upright helped hominids scan the ground for carcasses and carry tools. Those are useful abilities if you're scavenging. The detail supports the claim that their bodies could have suited that way of getting food.
Working the answers
- A
No earlier theory about how they walked is being corrected. The disputed theory concerns hunting.
- BCorrect
Upright walking is an example of being “well adapted for scavenging.” The two specific advantages—spotting carcasses and carrying tools—explain how it helped them obtain food.
- C
The fruit-heavy diet is inferred from wear on hominid teeth. Upright walking isn't offered as the reason for that dietary balance.
- D
The point isn't to make us appreciate their resemblance to modern humans. It's to explain an advantage for scavenging.
- E
This turns the example into a comparison about hunting live prey. The sentence explains how hominids could scavenge; it doesn't compare their hunting abilities with those of other mammals.
