QUESTION TYPE: Must be True
FACTS:
- Common sense is a time tested collection of useful theories.
- New, more useful theories will eventually take the place of current theories.
- Slow absorption of theories means that common sense contains some theories that are obsolete.
ANALYSIS: We don’t have any information about theories that are not currently part of common sense.
___________
- We don’t know this. In fact, common sense would tell us the older theories are more likely to be useful, as they have withstood the test of time.
- It’s not the frequency of new theories, but rather the slow process of change which prevents their absorption. It “absorbs new theories slowly.”
- Not necessarily true. There could be some theories which are perfect as they are, and will never be replaced.
- CORRECT. Yes. The slow process of absorption guarantees this. Until the theories are replaced, there will be some theories that are less useful than some others waiting to be absorbed.
