Statement :
All hotels are rooms.
All rooms are flats.
All flats are buildings.
No building is apartments.
Conclusion :
Some buildings may not be rooms.
Some apartments are not flats.
Some apartments are flats.
All hotels are buildings.
all rooms are flats (A) + All flats are buildings (A) → All rooms are buildings (A) → Conversion → some buildings are rooms (I) → probable conclusion → Some buildings may not be rooms (I). Hence, Conclusion I follows. All flats are buildings (A) + No building is an apartment (E)→ No flat is an apartment (E) → Conversion → Some apartments are not flats (O). Hence, conclusion II follows but Conclusion III does not follow. All hotels are room (A) + All rooms are flats (A) → All hotels are flats (A) + All flats are buildings (A) → All hotels are buildings. Hence, Conclusion IV follows.
