QUESTION TYPE: Parallel Reasoning
CONCLUSION: It’s silly to think that some animals could speak, but don’t.
REASONING: It’s like saying that some animals could fly, but don’t. Speaking and flight are both really useful.
ANALYSIS: The author is implying that it’s unlikely an ape could talk, but not use that power. It’s more likely that an ape can’t talk.
Likewise, a bird that looks like it could fly but doesn’t (e.g. ostrich, penguin), probably can’t fly. Flying is very useful.
___________
- It’s hard to assess this argument. Maybe there are some humans who don’t need sleep, or maybe there are some lions who can survive without meat.
- The alien argument would only match the explorer argument if it had had argued that aliens visited but never founded colonies.
- CORRECT. Both telekinetics and walking offer huge advantages. It would be strange if people and insects didn’t use these powers.
- This isn’t quite the same. Tobacco and alcohol can be fun, sure…but they offer lots of downsides. Flight and speaking don’t have any obvious downsides.
- I’m really not sure what to say to this. First, owning a car isn’t a physical characteristic. And some people do own cars without driving them.
Gasoline can have other uses apart from driving, so we might have invented it first.
