QUESTION TYPE: Role in Argument
CONCLUSION: Yang concludes that researchers should focus on the function of the brain rather than the structure.
REASONING: Yang claims that focusing on the structure will lead to failure. Flying machines modeled after birds all failed.
ANALYSIS: Subsidiary conclusions are fairly rare, and not well understood. It means a conclusion that is supported by evidence and supports the main conclusion. For example:
A ➞ B ➞ C
A is the evidence. It lets us conclude B, a subsidiary conclusion. B leads to C, the main conclusion.
___________
- The main conclusion is that researchers should focus on the function of the brain, because focusing on the structure will lead to failure.
- CORRECT. It is supported by the analogy about early flight machines and it supports the idea that we shouldn’t focus on the structure.
- It is not a principle of research. We don’t know how many people agree with Yang.
- This is true of the example about birds. But the statement about the brain structure is not a general claim.
- Yang hasn’t given us any context about the brain.
