Q: Answer the following question given this paragraph: Recall that air pollution is due to chemical substances and particles released into the air mainly by human actions. When most people think of air pollution, they think of the pollution outdoors. But it is just as easy to have indoor air pollution. Your home or school classroom probably doesn't get much fresh air. Sealing up your home reduces heating and cooling costs. But this also causes air pollution to stay trapped indoors. And people today usually spend a majority of their time indoors. So exposure to indoor air pollution can become a significant health risk. Q: What is caused by human actions that releases chemical substances and particles into the air? A:

OPTIONS:
- CFO pollution
- Improper Emissions
- heavy pollution
- air pollution

A: air pollution

input: OPTIONS:
- midocean
- poles
- trenches
- coastline Now, answer this question: Answer the following question given this paragraph: Ocean water is most polluted along coasts. That's because pollution usually enters the water from land. Oil spills also pollute ocean water. Q: Where would you find most pollution of ocean water? A:
A:
output: coastline

Answer the following question given this paragraph: Air in the troposphere is warmer closer to Earth's surface. Warm air is less dense than cool air, so it rises higher in the troposphere. This starts a convection cell. Convection mixes the air in the troposphere. Rising air is also a main cause of weather. All of Earth's weather takes place in the troposphere. Q: Why does warm air rise higher in the troposphere? A:

OPTIONS:
- it is more dense than cool air
- It contains hydrogen
- it is less flourishing than cool air
- it is less dense than cool air

Answer: it is less dense than cool air

Problem: OPTIONS:
- gravity
- acceleration
- velocity
- torque
Q: Answer the following question given this paragraph: This same logic explains the behavior of gyroscopes. Figure 10.31 shows the two forces acting on a spinning gyroscope. The torque produced is perpendicular to the angular momentum, thus the direction of the torque is changed, but not its magnitude. The gyroscope precesses around a vertical axis, since the torque is always horizontal and perpendicular to L . If the gyroscope is not spinning, it acquires angular momentum in the direction of the torque ( L falling over just as we would expect. Q: If a gyroscope is not spinning, it acquires angular momentum in the direction of what? A:
Answer: torque

Problem:OPTIONS:
- testicle
- thymus
- thyroid
- prostate gland

Answer the following question given this paragraph: The prostate gland secretes a fluid that mixes with sperm to help form semen. Semen is a whitish liquid that contains sperm. It passes through the urethra and out of the body. Q: What gland secretes a fluid that mixes with sperm to help form semen? A:
****
A:
prostate gland
