Background Paragraph: Light may transfer its energy to matter rather than being reflected or transmitted by matter. This is called absorption . When light is absorbed, the added energy increases the temperature of matter. If you get into a car that has been sitting in the sun all day, the seats and other parts of the car’s interior may be almost too hot to touch, especially if they are black or very dark in color. That’s because dark colors absorb most of the sunlight that strikes them. 
Story: There are two cats sitting outside in the sun. One of them has white fur and one of them has black fur. Tina sees them and goes to pet them both.         
                                                  Robert is planning a beach trip and needs to buy a new lounge chair to sit in because his old one is broken. At the store he sees two chairs that he likes. One of the chairs is dark blue and one of the chairs is light blue. 
Question: If left in the sun at the beach which chair color would become warmer the dark blue chair or the light blue chair?
the dark blue chair.

Background Paragraph: Often, foreign exchange controls can result in the creation of black markets to exchange the weaker currency for stronger currencies. This leads to a situation where the exchange rate for the foreign currency is much higher than the rate set by the government, and therefore creates a shadow currency exchange market. As such, it is unclear whether governments have the ability to enact effective exchange controls.[1]. 
Story: In the beginning of this century there was scandal in the financial market regarding black market trading. A trader named Trader A was working for Bank A. He noticed country M has pegged its currency to a fixed price while country N did not do that. He opted to trade country M currency. Across the aisle his colleague trader B was working for bank B. He traded country N's currency. 
Question: Would trader A be engaged or not be engaged in black market trading?
be engaged.

Background Paragraph: Alberta's electrical demand varies throughout the day and across the seasons. When individuals are fixing supper and using home appliances, demand for power goes up, as it does during heat waves and cold snaps. It tapers off during spring and fall. Like other mechanical devices, generators fail from time to time. If they are wind-powered, their output varies with the wind. 
Story: Greg works at a power facility in Alberta. He has been charged with regulating generators. His task is to turn on generators in times of high power demand, and to turn off generators at times of low power demand. He tries to remain as efficient as possible. Recently, the area has experienced record cold temperatures on Monday and Tuesday. By the weekend however, the temperature returned to normal, and Friday and Saturday the temperature was very moderate and spring like. 
Question: Would Greg have turned on more or less generators on Friday than Monday?

less.
