input with options: Answer the following question given this paragraph: Ocean waves are among the most impressive waves in the world. They clearly show that waves transfer energy. In the case of ocean waves, energy is transferred through matter. But some waves, called electromagnetic waves, can transfer energy without traveling through matter. These waves can travel through space. You can read more about electromagnetic waves in the chapter "Electromagnetic Radiation. " Waves that transfer energy through matter are the focus of the present chapter. These waves are called mechanical waves. Q: What term describes waves that transfer energy through matter? A:
OPTIONS:
- mechanical currents
- temperature waves
- energy currents
- mechanical waves
output: mechanical waves

- craters

Answer: craters

Problem: OPTIONS:

Q: Answer the following question given this paragraph: The angle of reflection equals the angle of incidence. A mirror has a smooth surface and reflects light at specific angles. Light is diffused when it reflects from a rough surface. Mirror images can be photographed and videotaped by instruments. Q: What kind of surface would cause diffusion when light is reflected off of it? A:
Answer: rough surfaces

Answer the following question given this paragraph: Adult frogs are characterized by long hind legs, a short body, webbed finger-like parts, and the lack of a tail. They also have a three-chambered heart, as do all tetrapods except birds and mammals. Most frogs live part of the time in water and part of the time on land. They move easily on land by jumping or climbing. To become great jumpers, frogs evolved long hind legs and long ankle bones. They also have a short backbone with only ten vertebrae. Frog and toad skin hangs loosely on the body, and skin texture can be smooth, warty, or folded. Q: Like all tetrapods except birds and mammals, frogs possess a heart with what structure? A:

OPTIONS:
- One Chamber
- four chambers
- eight chambers
- three chambers

Answer:
three chambers
