QUESTION TYPE: Must Be True
FACTS: Mice are kept in small cages. That’s not healthy or normal. Mice aren’t as useful for research if we keep them in a non-normal environment.
ANALYSIS: You can connect the premises.
Small cages ➞ Normal ➞ Useful
Keeping mice in small cages makes them less useful for research.
Normally on a test I’d draw that with letters, not words, but the words make it clearer for a book.
- We’re not told whether there will be any changes.
- We have no idea what’s appropriate. It might be appropriate to use mice even if they’re not kept in normal conditions. Or maybe it’s always wrong to experiment on mice.
- CORRECT. You get this from combining the premises. The non-normal conditions in the cages make the mice less useful for research.
- We’re not told anything about how scientists develop new techniques.
- We aren’t told anything about other mice.
