# 3. If a red house is made from red bricks and a blue house is made from blue bricks and a pink house is made from pink bricks and a black house is made from black bricks, what is a green house made from?
Answer: Greenhouses are made from glass.
The question was "what is a green house made from"? The correct answer could be green bricks in the context of the question.
If the questions had been "what are greenhouses" made of or "what is a greenhouse" made of the answer could be "glass".
There is a difference between a greenhouse and a green house.
On the green house my answer was you don’t know. It could be made from wood.
