Statements : All cups are glasses. Some glasses are bowls. No bowl is a plate.

Conclusions :
I. No cup is a plate.
II. No glass is a plate.
III. Some plates are bowls.
IV. Some cups are not glasses.

Explanation:-

All cups are glasses. Some glasses are bowls.

Since the middle term 'glasses' is not distributed even once in the premises, no definite conclusion follows.

Some glasses are bowls. No bowl is a plate.

Since one premise is particular and the other negative, the conclusion must be particular negative and should not contain the middle term. So, it follows that 'Some glasses are not plates'.
