QUESTION TYPE: Flawed Reasoning
CONCLUSION: The new process will cost a lot but won’t bring any profits.
REASONING: The new equipment costs a lot to install and costs more to run.
ANALYSIS: We’re supposed to ignore the supervisor when we answer this as we’re only evaluating the plant manager’s argument.
This is tricky, but the manager is only talking about costs. Yet his conclusion is about profits. There could be something about the new process that increases profits. Maybe people will pay more for copper that is environmentally friendly and doesn’t produce as much sulfur dioxide (for example.)
- CORRECT. The manager only considers cost and doesn’t prove that there are no monetary advantages to the new process.
- The plant manager says that the new equipment costs money to buy and costs more to run. It should be possible to check whether that information is true.
- This doesn’t happen, conclusion actually goes beyond the evidence by stating that there are no profits.
In any case, it’s not bad to repeat the evidence if you’re combining different pieces of evidence to form a single confusion (that’s different from circular reasoning.)
- The manager doesn’t say anything is only “probably true.”
- What facts aren’t relevant? The manager says what the method requires and what it costs and then makes a conclusion based on that evidence.
