Answer the following question given this paragraph: Because electricity can be so dangerous, safety features are built into modern electric circuits and devices. They include three-prong plugs, circuit breakers, and GFCI outlets. You can read about these three safety features in the Figure below . You can learn more about electric safety features in the home by watching the video at this URL: http://www. dailymotion. com/video/x6fg5i_basics-of-your-home-s-electrical-sy_school . Q: Three-prong plugs, circuit breakers, and gfci outlets are safety features that recognize the danger of what? A:
OPTIONS:
- heat
- magnetism
- gravity
- electricity
electricity

Answer the following question given this paragraph: As you can see in the Figure above , the electric and magnetic fields that make up an electromagnetic wave are perpendicular (at right angles) to each other. Both fields are also perpendicular to the direction that the wave travels. Therefore, an electromagnetic wave is a transverse wave. However, unlike a mechanical transverse wave, which can only travel through matter, an electromagnetic transverse wave can travel through empty space. When waves travel through matter, they lose some energy to the matter as they pass through it. But when waves travel through space, no energy is lost. Therefore, electromagnetic waves don't get weaker as they travel. However, the energy is "diluted" as it travels farther from its source because it spreads out over an ever-larger area. Q: What may be lost when waves travel through matter, but not when they travel through space? A:
OPTIONS:
- matter
- frequency
- threshold
- energy

Answer: energy

Question: Answer the following question given this paragraph: Pearls are highly valued as gemstones. Most gemstones come from the Earth, but pearls come from living things. They are created by mollusks, such as oysters. Q: What gems are created by mollusks, such as oysters? A:
OPTIONS:
- crystals
- turquoise
- diamonds
- pearls
Answer: pearls

input with options: Answer the following question given this paragraph: Erosion moves sediments after they have formed. The sediments are transported away from the place where they form. There are several agents of erosion. Flowing water moves and deposits sediments. Water erodes far more material than any other erosional agent. Wind is important as an agent of erosion. This is especially true in arid climates. Ice, in glaciers, can erode enormous quantities of sediments. Gravity as a force of erosion pulls material downhill. Q: What moves sediments after they have formed? A:
OPTIONS:
- photosynthesis
- migration
- perspiration
- erosion
output: erosion

Q: Answer the following question given this paragraph: Feathers help birds fly and also provide insulation and serve other purposes. Birds actually have two basic types of feathers: flight feathers and down feathers. Both are shown in Figure below . Flight feathers are long, stiff, and waterproof. They provide lift and air resistance without adding weight. Down feathers are short and fluffy. They trap air next to a bird's skin for insulation. Q: Birds actually have two basic types of feathers: flight feathers and? A:

OPTIONS:
- colorful plumes
- landing feathers
- shed feathers
- down feathers

A: down feathers

Answer the following question given this paragraph: Biogeography is the study of how and why plants and animals live where they do. It provides more evidence for evolution. Let's consider the camel family as an example. Q: What is the study of how and why plants and animals live where they do? A:
OPTIONS:
- geomorphology
- heredity
- lithography
- biogeography
