Answer the following question given this paragraph: Some materials are natural permanent magnets. The most magnetic material in nature is the mineral magnetite, also called lodestone (see Figure below ). The magnetic domains of magnetite naturally align with Earth's axis. The picture on the left shows a chunk of magnetite attracting small bits of iron. The magnetite spoon compass shown on the right dates back about 2000 years and comes from China. The handle of the spoon always points north. Clearly, the magnetic properties of magnetite have been recognized for thousands of years. Q: Also called lodestone, the mineral magnetite is the most powerful what? A:
OPTIONS:
- material on Earth
- synthetic magnet
- healing magnet
- natural permanent magnet
natural permanent magnet

Answer the following question given this paragraph: When gas molecules bump into things, it creates pressure. Pressure is greater when gas molecules occupy a smaller space, because greater crowding results in more collisions. This explains why decreasing the volume of a gas increases its pressure. Q: Decreasing the volume of a gas and keeping everything else the same will cause its pressure to change in what way? A:
OPTIONS:
- heat up
- decrease
- lower
- increase

Answer: increase
