Answer the following question given this paragraph: Photosynthesis provides over 99 percent of the energy for life on earth. A much smaller group of autotrophs - mostly bacteria in dark or low-oxygen environments - produce food using the chemical energy stored in inorganic molecules such as hydrogen sulfide, ammonia, or methane. While photosynthesis transforms light energy to chemical energy, this alternate method of making food transfers chemical energy from inorganic to organic molecules. It is therefore called chemosynthesis , and is characteristic of the tubeworms shown in Figure below . Some of the most recently discovered chemosynthetic bacteria inhabit deep ocean hot water vents or "black smokers. " There, they use the energy in gases from the Earth's interior to produce food for a variety of unique heterotrophs: giant tube worms, blind shrimp, giant white crabs, and armored snails. Some scientists think that chemosynthesis may support life below the surface of Mars, Jupiter's moon, Europa, and other planets as well. Ecosystems based on chemosynthesis may seem rare and exotic, but they too illustrate the absolute dependence of heterotrophs on autotrophs for food. Q: What process provides over 99 percent of the energy for life on earth? A:

OPTIONS:
- farming
- glycolysis
- fracking
- photosynthesis

Answer: photosynthesis

Q: Answer the following question given this paragraph: Hot spots are found within continents, but not as commonly as within oceans. The Yellowstone hot spot is a famous example of a continental hot spot. Q: The yellowstone hot spot is a famous example of a what? A:
Answer: continental hot spot

Answer the following question given this paragraph: An amine consists of a nitrogen atom bonded to some combination of carbons and hydrogens. Q: What consists of a nitrogen atom bonded to some combination of carbons and hydrogens? A:
****
A: an amine

Answer the following question given this paragraph: Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis ( Figure below ) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels. Q: Cellular respiration and photosynthesis are important parts of which cycle? A:
OPTIONS:
- vapor cycle
- greenhouse effect
- water cycle
- carbon cycle
carbon cycle

Answer the following question given this paragraph: Despite its dangers, radioactivity has several uses. It can be used to determine the ages of ancient rocks and fossils. This use of radioactivity is explained in this chapter's "Radioactive Decay" lesson. Radioactivity can also be used as a source of power to generate electricity. This use of radioactivity is covered later on in this chapter in the lesson "Nuclear Energy. " Radioactivity can even be used to diagnose and treat diseases, including cancer. Cancer cells grow rapidly and take up a lot of glucose for energy. Glucose containing radioactive elements can be given to patients. Cancer cells will take up more of the glucose than normal cells do and give off radiation. The radiation can be detected with special machines (see Figure below ). Radioactive elements taken up by cancer cells may also be used to kill the cells and treat the disease. You can learn more about medical uses of radiation at the URL below. Q: What type of disease can be treated by radioactive elements in glucose? A:
OPTIONS:
- mutation
- infection
- genetic disorder
- cancer

Answer: cancer

input with options: Answer the following question given this paragraph: The metals of group 13 (Al, Ga, In, and Tl) are all reactive. However, passivation occurs as a tough, hard, thin film of the metal oxide forms upon exposure to air. Disruption of this film may counter the passivation, allowing the metal to react. One way to disrupt the film is to expose the passivated metal to mercury. Some of the metal dissolves in the mercury to form an amalgam, which sheds the protective oxide layer to expose the metal to further reaction. The formation of an amalgam allows the metal to react with air and water. Q: The formation of an amalgam allows the metal to react with what? A:
OPTIONS:
- helium and oxygen
- cloth and plastic
- blood and sweat
- air and water
output:
air and water
