Statement: All sands are beaches. All shores are beaches. Some beaches are trees. All trees are hotels. Conclusions: I. Some shores are hotels. II. All beaches are shores III. Some beaches are hotels. IV. Some sands are trees.

Some beaches are tree + All trees are hotels = I + A = I = Some beaches are hotels Hence III follows. Now, All shores are beaches + Some beaches are hotels = A + I = No conclusion Hence I does not follow. All shores are beaches (A) → conversion → Some beaches are shores (I). Hence II does not follow. All sands are beaches + Some beaches are trees = A + I = No conclusion Hence IV does not follow.
