Statements:
Only buses are cars
Only a few buses are trains
No train is a bike
Conclusions:
I. Some cars is being bikes is a possibility
II. All trains is being buses is a possibility
III. Some bikes are buses
Car cannot have any relation with anyone. Hence conclusion I does not follow. Only a few buses are trains → Probable conclusion → All trains may be buses (A). Hence conclusion II follows. Some buses are trains (I) + No train is a bike (E) → Some buses are not bikes (O). Hence conclusion III does not follow.
