Was the boat red? 

The boat was red. 

He and I met on the red boat. 

They met on that red boat. 

I met his maid on the red boat. 

His hat is red. 

His hat is as red as the boat. 

The boat is as red as his hat. 

I hid his red hat. 

I hid his hat on that red boat.

He hid his red hat. 

They hid his red hat.
