If a red house is made from red bricks, a blue house is made from blue bricks, a pink house is made from pink bricks, and a black house is made from black bricks.
The correct answer to this question is Glass. It is easy to get tripped up on this question because of all the other houses listed being made from their corresponding names. One difference is that greenhouse is one word, while the blue house, pink house, and red house are all two words.
The latter is describing the color of the house, while the greenhouse is alluding to the real thing. A greenhouse is also known as a glass house. Plants that need regulated climates to thrive are grown there. Various things can be controlled in a greenhouse, including light and temperature. They are popularly used to produce fruits, flowers, and vegetables.
The answer may seem obvious in the beginning and most people would probably say that the greenhouse is made of green bricks because the other colored houses are made with their corresponding colored bricks. The thing is, the greenhouse is not really a house wherein people can live.
Rather, this is a space for your plants so that they can thrive properly. Greenhouses are usually made of glass in order to allow the sunlight to penetrate and provide the needed sunlight by the plants that will be housed inside the greenhouse. Greenhouses may vary when it comes to size and even shape.
