QUESTION TYPE: Principle – Parallel Reasoning
PRINCIPLE: You should have someone else check your work: they’ll be better at catching errors. It’s easier to spot someone else’s errors than to see your own.
ANALYSIS: Most of the wrong answers ignore the two elements from the stimulus:
1. We want to catch errors.
2. Someone else should do it, because they aren’t you. You can’t see your own mistakes.
Answer D is a straightforward application of the principle. Sometimes (but not often) the correct answer has a situation similar to the stimulus.
___________
- This has nothing to do with having someone check your work. It’s just a statement about teachers’ math abilities.
- This does talk about how it’s easier to understand our own views. But that’s the opposite of the stimulus: it was easier to spot someone else’s errors. And this has nothing to do with checking work.
- This does talk about catching errors. But the stimulus talked about having someone else check your work, simply because they weren’t you. This is a different situation.
- CORRECT. This is exactly the same principle: someone else is more likely than you to catch your errors.
- This doesn’t talk about catching errors.
