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.
