Only members can use the library. Bilal is using the library. Which conclusion follows?
- A. Bilal is a member
- B. Bilal is not a member
- C. Bilal is a student
- D. Nothing follows
Explanation
The word only makes membership a necessary condition for use, so anyone using the library must be a member. This is the reverse of the usual if then structure, which is why only sentences must be read carefully. Being a member, however, would not guarantee that he uses it.
