Q: Background Paragraph: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution that harms the health of living things. The air pollution also causes acid rain and contributes to global warming. In addition, fossil fuels are nonrenewable resources, so if we keep using them, they will eventually run out. The main advantage of nuclear energy is that it doesn’t release air pollution or cause the other environmental problems associated with the burning of fossil fuels. On the other other hand, radioactive elements are nonrenewable like fossil fuels and could eventually be used up. 
Story: Thorn county used fossil fuels for their energy needs, while Plant county used nuclear power. They both polluted the environment in different ways. 
Question: Which county released more air pollution?

A: Thorn.

Q: Background Paragraph: More than 170 million years ago, Antarctica was part of the supercontinent Gondwana. Over time, Gondwana gradually broke apart, and Antarctica as we know it today was formed around 25 million years ago. Antarctica was not always cold, dry, and covered in ice sheets. At a number of points in its long history, it was farther north, experienced a tropical or temperate climate, was covered in forests, and inhabited by various ancient life forms. 
Story: John was reading about a fascinating story of a scientist in a science fiction book. In that novel the scientist met with a mysterious wormhole while visiting Antarctica. First, the wormhole started the time travel in present day, which was designated as point A. Then it sent the scientist to 170 million years in the past, which was designated as point B. The scientist had the rare experience of visiting Antarctica in two different time periods, 170 million years apart. 
Question: Which point would see less ice sheets, point A or point B?

A: point B.

Q: Background Paragraph: Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment. 
Story: A research institute is investigating the effect of alcohol in human body. They gave two groups of subjects, group blue and group red, two different drinks, labeled as blue drink and red drink. The blue drink contained alcohol, and the red drink did not contain any alcohol. Blue drinks were given to the blue group and the red drinks were given to the red group. 
Question: Would blue group have more or less warm blood near the surface of the skin than red group?

A:
more.
