Statements: Some bottles are drinks. All drinks are cups.
Conclusions:
I. Some bottles are cups
II. Some cups are drinks
III. All drinks are bottles
IV. All cups are drinks.
Solution
Some bottles are drinks, and every drink is a cup. Therefore those bottles are also cups, so conclusion 1 follows.
Because some drinks exist and every drink is a cup, some cups are drinks, so conclusion 2 follows.
The reverse universal statements in 3 and 4 do not follow.
Hence only 1 and 2 follow.
