[Q]: Background: Submarine volcanoes are common features of the ocean floor. In shallow water, active volcanoes disclose their presence by blasting steam and rocky debris high above the ocean's surface. In the ocean's deep, the tremendous weight of the water above prevents the explosive release of steam and gases; however, they can be detected by hydrophones and discoloration of water because of volcanic gases. Pillow lava is a common eruptive product of submarine volcanoes and is characterized by thick sequences of discontinuous pillow-shaped masses which form under water. Even large submarine eruptions may not disturb the ocean surface due to the rapid cooling effect and increased buoyancy of water (as compared to air) which often causes volcanic vents to form steep pillars on the ocean floor. Hydrothermal vents are common near these volcanoes, and some support peculiar ecosystems based on dissolved minerals. Over time, the formations created by submarine volcanoes may become so large that they break the ocean surface as new islands or floating pumice rafts. Paragraph: Planet X had two large oceans. Ice ocean had few submarine volcanoes, while Tropical ocean had thousands of active volcanoes on the ocean floor. Given the paragraph above, please answer correctly the following question: Which ocean had fewer volcanoes blasting steam high above its surface?
****
[A]: Ice

input: Please answer the following: Background: The earliest members of the human species evolved around 200,000 years ago in Africa. Early humans lived in small populations of nomadic hunters and gatherers. Human beings remained in Africa until about 40,000 years ago. After that, they spread throughout Europe, Asia, and Australia. By 10,000 years ago, the first human beings colonized the Americas. During this long period of time, the total number of human beings increased very slowly. Birth rates were fairly high but so were death rates, producing low rates of population growth. Paragraph: Research team Alpha learned about early human activities, from 200000 years ago, while team Gamma learned about late human activities, 40000 years ago to present times. Given the paragraph above, please answer correctly the following question: Which team learned about the spread of humans to Asia?
++++++++++
output: team Gamma

Please answer this: Background: Ecology is the study of ecosystems. An ecosystem consists of all the living and nonliving components of the habitat. Whereas nutrients and certain elements are recycled through ecosystems, energy moves in just one direction. Many interactions among species within an ecosystem are centered around the flow of energy. The formation of ecosystems, from new land to current habitats, is usually based on the pioneer species, and these species are able to live in an area due to the nonliving factors, such as the climate, the soil and the amount of rainfall, of that area. The populations within an ecosystem also determine the stability of the system. Recent tremendous increases in the human population have raised many important ecological issues. Paragraph: Two friends were into natural sciences. Tom was more into Geology, while Rick studied Ecology. Given the paragraph above, please answer correctly the following question: Which student read more about living components of the habitat?
++++++++
Answer: Rick

Problem: Background: Two important devices depend on electromagnetic induction: electric generators and electric transformers. Both devices play critical roles in producing and regulating the electric current we depend on in our daily lives. Electric generators use electromagnetic induction to change kinetic energy to electrical energy. They produce electricity in power plants. Electric transformers use electromagnetic induction to change the voltage of electric current. Some transformers increase voltage and other decrease voltage. Paragraph: Bob works for the local electric power company. Part of is job involves checking the generators and transformers. His work schedule allows him to work on the generator tagged as gen A only on Mondays, and the transformer tagged as tran B only on Tuesdays. Given the paragraph above, please answer correctly the following question: Which one would not produce electric current, gen A or tran B?

A: tran B

Problem: Given the question: Background: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. Paragraph: Panama and Ecuador are two neighboring countries. Ecuador uses nuclear fusion to produce its electricity, while Panama uses fossil fuels. Given the paragraph above, please answer correctly the following question: Which country caused less acid rain?
++++++++++++++++++++++++++++++++
The answer is:
Ecuador

Problem: Background: Bernoulli's law explains how the wings of both airplanes and birds create lift that allows flight (see Figure below ). The shape of the wings causes air to flow more quickly and air pressure to be lower above the wings than below them. This allows the wings to lift the plane or bird above the ground against the pull of gravity. A spoiler on a race car, like the one in Figure below , works in the opposite way. Its shape causes air to flow more slowly and air pressure to be greater above the spoiler than below it. As a result, air pressure pushes the car downward, giving its wheels better traction on the track. Paragraph: Rob is experimenting with how air pressure works. To that end, he has designed two tests. In the first test the air flow works as it would in an airplane wing. He labels it as case A. In the second test the air flow works as it would in a race car spoiler. He labels it as case B. He is surprised to see that air flow behaves differently in different situations. Given the paragraph above, please answer correctly the following question: Would case B have faster or slower air flow above it than case A?

A:
slower
