Problem: Given the question: Background: The Hawaiian Islands ( Figure above ) are in the central Pacific Ocean. The islands are volcanoes that increase in age from southeast to northwest. The youngest island is the Big Island of Hawaii at the southeast end of the chain. The volcanoes get older through Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau Islands through the northwest. The Kilauea volcano on Hawaii has been erupting almost continuously since 1983. There are also eruptions at an underwater volcano called Loih Paragraph: Tom and Brad were good friends but lived far away from each other. Tom lived in Hawaii so he visited all the islands and the volcanoes frequently. Brad lived on the East Coast, and he never visited The Hawaiian Islands. Given the paragraph above, please answer correctly the following question: Which friend lived closer to the Big Island of Hawaii?
++++++++++++++++++++++++++++++++
The answer is:
Tom

Problem: Given the question: Background: Greenhouse Effect: The solar energy reaching the surface of the Earth is concentrated in short wavelengths, which can easily penetrate the greenhouse gases, such as carbon dioxide and methane. The Earth, however, is cooler than the sun and it radiates its heat in the form of energy in the far infrared range. These longer wavelengths are partially absorbed by the greenhouse gases and some of the solar heat is returned to Earth. At a certain temperature these processes are in equilibrium and the surface temperature of the Earth is stable. However, if more greenhouse gases are put in the atmosphere the amount of trapped terrestrial radiation increases, leading to an increase in global temperature. Paragraph: John was interested in climate change issues. To that end, he studied two imaginary situations, case A and case B. In case A, there would not be excessive greenhouse gases in the atmosphere. On the contrary, in case B, the amount of greenhouse gases in the atmosphere would increase dramatically. John realized that the amount of greenhouse gases in the atmosphere has many practical implications. Given the paragraph above, please answer correctly the following question: In case A would less or more of the longer wavelength be absobed in the atmosphere than case B?
++++++++++++++++++++++++++++++++
The answer is:
less

Problem: Given the question: Background: Other pathogens spread when they get on objects or surfaces. A fungus may spread in this way. For example, you can pick up the fungus that causes athlete's foot by wearing shoes that an infected person has worn. You can also pick up this fungus from the floor of a public shower or other damp areas. After acne, athlete's foot is the most common skin disease in the United States. Therefore, the chance of coming in contact with the fungus in one of these ways is fairly high. Paragraph: Two brothers worked out a few times per week at the same gym. Tim got athlete's food from the gym, but Dan didn't. Given the paragraph above, please answer correctly the following question: Which brother did not pick up the fungus from the floor of a public shower?
++++++++++++++++++++++++++++++++
The answer is:
Dan
