A smiling man with gray hair and glasses, dressed in black, is sitting in a chair with a music stand in front of him.
This bald man stands naked in protest of fur for fashion.
The man can't have gray hair, be dressed in black and sitting while at the same time being bald and standing naked.
A man can't be bald and have gray hair, nor can he sit and stand at the same time.
The man cannot be both bald and have gray hair. The man cannot be both dressed in black and naked.
