Question: Answer the following question given this paragraph: Earth and Moon orbit each other. This Earth-Moon system orbits the Sun in a regular path ( Figure below ). Gravity is the force of attraction between all objects. Gravity keeps the Earth and Moon in their orbits. Earth's gravity pulls the Moon toward Earth's center. Without gravity, the Moon would continue moving in a straight line off into space. Q: What keeps the earth orbiting the sun? A:
OPTIONS:
- strong nuclear force
- magnetic force
- weak nuclear force
- gravity
Answer: gravity

input with options: Answer the following question given this paragraph: Nitrogen oxides form when nitrogen and oxygen combine at high temperatures. This occurs in hot exhausts from vehicles, factories, and power plants. Q: What forms when nitrogen and oxygen combine at high temperatures? A:
OPTIONS:
- oxygen oxide
- ammonia oxide
- carbon dioxide
- nitrogen oxide
output: nitrogen oxide

Q: Answer the following question given this paragraph: ART CONNECTION QUESTIONS 1. Figure 5.7 On a hot, dry day, plants close their stomata to conserve water. What impact will this have on photosynthesis?. Q: On a hot, dry day, plants close their stomata to conserve what? A:

OPTIONS:
- sunlight
- air
- cold
- water

A: water

input: OPTIONS:
- natural
- weather
- conditions
- environment Now, answer this question: Answer the following question given this paragraph: All organisms must adapt to their environment in order to survive. This is true whether they live in water or on land. Most environments are not as extreme as the deep ocean where tube worms live. But they all have conditions that require adaptations. In this chapter, you will read about a wide variety of environments and the organisms that live in them. Q: All organisms must adapt to what in order to survive? A:
A:
output: environment

Answer the following question given this paragraph: The amount of kinetic energy in a moving object depends directly on its mass and velocity. An object with greater mass or greater velocity has more kinetic energy. You can calculate the kinetic energy of a moving object with this equation:. Q: The amount of kinetic energy in a moving object depends directly on its mass and what else? A:

OPTIONS:
- volume
- direction
- density
- velocity

Answer: velocity

Q: Answer the following question given this paragraph: 15.6 Entropy and the Second Law of Thermodynamics: Disorder and the Unavailability of Energy Entropy is the loss of energy available to do work. Another form of the second law of thermodynamics states that the total entropy of a system either increases or remains constant; it never decreases. Entropy is zero in a reversible process; it increases in an irreversible process. The ultimate fate of the universe is likely to be thermodynamic equilibrium, where the universal temperature is constant and no energy is available to do work. Entropy is also associated with the tendency toward disorder in a closed system. Q: What is the loss of energy available to do work called? A:

OPTIONS:
- negentropy
- force
- power
- entropy

A:
entropy
