Problem:OPTIONS:
- fossil record
- renewable resources
- non-renewable fuel
- fossil fuels

Answer the following question given this paragraph: Fossil fuels are mixtures of hydrocarbons that formed over millions of years from the remains of dead organisms. They include petroleum (commonly called oil), natural gas, and coal. Fossil fuels provide most of the energy used in the world today. They are burned in power plants to produce electrical energy, and they also fuel cars, heat homes, and supply energy for many other purposes. You can see examples of their use in Figure below . Q: What is the common name of mixtures of hydrocarbons that formed over millions of years from the remains of dead organisms? A:
****
A: fossil fuels

Answer the following question given this paragraph: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. Q: What weather phenomenon increases the rate of weathering in rock and soil? A:
OPTIONS:
- temperature
- earthquake
- landslide
- rainfall
rainfall

Answer the following question given this paragraph: The Kyoto Protocol is another worldwide agreement on air pollution. It was passed in 1997. The Protocol focuses on controlling greenhouse gas emissions. Its aim is to control global warming. Q: What does the kyoto protocol focus on controlling? A:
OPTIONS:
- carbonate gas emissions
- Helium emissions
- Ozone emissions
- greenhouse gas emissions

Answer: greenhouse gas emissions

Question: Answer the following question given this paragraph: Electron dot diagrams can be used to illustrate electron movements and ion formation. Q: What kind of diagrams can be used to illustrate electron movements and ion formation? A:
OPTIONS:
- venn diagrams
- atomic models
- contour maps
- electron dot diagrams
Answer: electron dot diagrams

input with options: Answer the following question given this paragraph: 19.3 The Human Population Earth's human population is growing exponentially. Humans have increased their carrying capacity through technology, urbanization, and harnessing the energy of fossil fuels. The age structure of a population allows us to predict population growth. Unchecked human population growth could have dire long-term effects on human welfare and Earth's ecosystems. Q: Human population is growing exponentially and humans have increased what normally limiting factor through technology, urbanization, and harnessing the energy of fossil fuels? A:
OPTIONS:
- zero population growth
- mass extinction
- habitat loss
- carrying capacity
output: carrying capacity

Problem: OPTIONS:
- nitrogen
- oxygen
- hydrogen
- carbon
