DISCUSSION: The status signaling hypothesis is not a certainty. It’s just a hypothesis.
The first paragraph introduces this hypothesis. Then the author examines two studies.
One study fails to support the hypothesis, while the other study does support the hypothesis.
___________
- CORRECT. The first paragraph introduces the status signaling hypothesis. The first study doesn’t support the hypothesis, while the second study does.
- It’s not certain that birds actually do signal status with feathers. That’s just a hypothesis. And there are no “explanations” for the phenomenon. The studies attempt to prove the hypothesis, not explain it.
- Same as B. There were no explanations or causes presented.
- There’s no conundrum, only a hypothesis. And we’re never told the history of the hypothesis.
- No study that aimed to disprove the hypothesis. There was only a study that failed to support the hypothesis.
