Q: Answer the following question given this paragraph: Conduction from the core heats the lower mantle. Q: Conduction from the core has what effect on the lower mantle? A:
Answer: it heats it

Problem:OPTIONS:

Answer the following question given this paragraph: Unsaturated hydrocarbons contain at least one double or triple bond between carbon atoms. As a result, the carbon atoms are unable to bond with as many hydrogen atoms as they would if they were joined only by single bonds. This makes them unsaturated with hydrogen. Unsaturated hydrocarbons are classified on the basis of their bonds as alkenes, alkynes, or aromatic hydrocarbons. Q: What type of hydrocarbons contain at least one double or triple bond between carbon atoms? A:
****
A: unsaturated

Answer the following question given this paragraph: Water pollution comes from many sources. One of the biggest sources is runoff. Runoff picks up chemicals such as fertilizer from agricultural fields, lawns, and golf courses. It carries the chemicals to bodies of water. The added nutrients from fertilizer often cause excessive growth of algae, creating algal blooms (see Figure below ). The algae use up oxygen in the water so that other aquatic organisms cannot survive. This has occurred over large areas of the ocean, creating dead zones , where low oxygen levels have killed all ocean life. A very large dead zone exists in the Gulf of Mexico. Measures that can help prevent these problems include cutting down on fertilizer use. Preserving wetlands also helps because wetlands filter runoff. Q: What source of water pollution picks up chemicals from the ground with water and carries them to bodies of water? A:
OPTIONS:
- fertilizer
- erosion
- sediment
- runoff
runoff

Answer the following question given this paragraph: When water freezes in a non-crystalline, amorphous form as frost, the water molecules are fixed in place, but not in a regular, repeating pattern. Frost and other amorphous solids are characterized by their unorganized and unpredictable structure. Because ice comes in both amorphous and crystalline forms, there are differences in the physical properties of ice such as its hardness and density. Q: What kind of solid is characterized by an unorganized and unpredictable structure? A:
OPTIONS:
- magnetic
- aqueous
- porous
- amorphous

Answer: amorphous

input with options: Answer the following question given this paragraph: Q: What is given off from plants and taken in by animals? A:
OPTIONS:
- methane
- sulfur
- nitrogen
- oxygen
output:
oxygen
