Input: Imagine you are standing in a farm field in central Illinois. The land is so flat you can see for miles and miles. On a clear day, you might see a grain silo 20 miles away. You might think to yourself, it sure is flat around here. If you drive one hundred miles to the south, the landscape changes. In southern Illinois, there are rolling hills. Why do you think this is? What could have caused these features? There are no big rivers that may have eroded and deposited this material. The ground is capable of supporting grass and trees, so wind erosion would not explain it. To answer the question, you need to go back 12,000 years. Around 12,000 years ago, a giant ice sheet covered much of the Midwest United States. Springfield, Illinois, was covered by over a mile of ice. Its hard to imagine a mile thick sheet of ice. The massive ice sheet, called a glacier, caused the features on the land you see today. Where did glaciers go? Where can you see them today? Glaciers are masses of flowing ice.

Does the response "20 miles wide" correctly answer the question "How big were the glaciers?"?

Input: The world can be divided into three climate zones. The first climate zone is the polar zone. As it sounds, the polar zone is near earths poles. The polar zone has very long and cold winters. Brrr!!!! Near the equator is the tropical zone. The tropical zone is known for being hot and wet. Between these two zones is the temperate zone. Temperatures there tend to be mild. Its not too hot and not too cold. You might expect places near the equator to be hot and wet. Thats not always the case. Sometimes there are other factors at work. These factors can affect the local climate type or a region. Oceans and mountain ranges can have a major impact. They can greatly influence the climate of an area. Many factors influence an areas climate.

Does the response "Tropical" correctly answer the question "What are the world's three climate zones?"?

Output: yes

Input: An atom is the very smallest particle that still the elements properties. All the atoms of an element are alike. They are also different from the atoms of all other elements. For example, atoms of gold are always the same. It does not matter if they are found in a gold nugget or a gold ring. All gold atoms have the same structure and properties. For example, all gold atoms contain 79 protons. One of golds unique properties is that it is a great conductor of electricity. Gold is a better conductor of electricity than copper. Gold is more rare and expensive than copper. Copper is used in house wiring. Gold is far too expensive.

Does the response "Gold is more rare and expensive than copper and is a better conductor of electricity" correctly answer the question "What are differences between gold and copper?"?

Output: yes

Input: Tropical climates are found around the equator. These climates have warm temperatures year round. Tropical climates may be very wet or wet and dry. Tropical wet climates occur at or very near the equator. They have high rainfall year round. Tropical rainforests grow in this type of climate. Tropical wet and dry climates also occur near the equator. They receive less rainfall. Most of the rain falls in a single season. The rest of the year is dry. Few trees can withstand the long dry season. The main plants are grasses. Dry climates receive very little rainfall. They also have high rates of evaporation. This makes them even drier. Deserts can get less than 25 centimeters of rain per year. Thats less than 10 inches per year. How much rain do you get at your house?

Does the response "They recieve rainfall all year long" correctly answer the question "How much of the year do tropical rainforests receive high rainfall?"?
