Answer the following question given this paragraph: A low level of radiation occurs naturally in the environment. This is called background radiation. One source of background radiation is rocks, which may contain small amounts of radioactive elements such as uranium. Another source is cosmic rays. These are charged particles that arrive on Earth from outer space. Background radiation is generally considered to be safe for living things. You can learn more about background radiation with the animation at this URL: http://www. pbs. org/wgbh/nova/dirtybomb/sources. html. Q: A low level of radiation occurs naturally in the environment and is called what? A:
OPTIONS:
- Gamma radiation
- Beta radiation
- Alpha radiation
- background radiation

Answer: background radiation

Question: Answer the following question given this paragraph: Cerebral palsy is a disease caused by injury to the developing brain. The injury occurs before, during, or shortly after birth. Cerebral palsy is more common in babies that have a low weight at birth. But the cause of the brain injury is not often known. The disease usually affects the parts of the brain that control body movements. Symptoms range from weak muscles in mild cases to trouble walking and talking in more severe cases. There is no known cure for cerebral palsy. Q: Cerebral palsy is a disease caused by injury to what organ as it is developing? A:
OPTIONS:
- heart
- skin
- liver
- brain
Answer: brain

input with options: Answer the following question given this paragraph: Competition between different species is called interspecific competition. It might lead to the less well-adapted species going extinct. Or it might lead to one or both species evolving specialized adaptations. For example, competing species might evolve adaptations that allow them to use different food sources. You can see an example in Figure below . Q: A potential cause of extinction, competition between different species is called what? A:
OPTIONS:
- parasitism
- intraspecific competition
- mutualism
- interspecific competition
output: interspecific competition

Q: Answer the following question given this paragraph: Most ocean mollusks have a gill or gills to absorb oxygen from the water. Q: What do ocean mollusks use to absorb oxygen from the water? A:

OPTIONS:
- shells
- scales
- pores
- gills

A: gills

input: OPTIONS:
- peristalsis
- ketosis
- consciousness
- homeostasis Now, answer this question: Answer the following question given this paragraph: Lenses are made of transparent material such as glass or plastic with an index of refraction greater than that of air. At least one of the faces is a part of a sphere; a convex lens is thicker at the center than the edges, and a concave lens is thicker at the edges than the center. Convex lenses are called converging lenses, because they refract parallel light rays so that they meet. They are one of the most useful and important parts of all optical devices, and are found in eyeglasses, telescopes, microscopes, magnifying glasses, cameras and many other objects. Q: What is defined as maintaining a stable internal environment? A:
A:
output: homeostasis

Question: Answer the following question given this paragraph: Fossil fuels are made from plants and animals that lived hundreds of millions of years ago. The plants and animals died. Their remains settled onto the ground and at the bottom of the sea. Layer upon layer of organic material was laid down. Eventually, the layers were buried very deeply. They experienced intense heat and pressure. Over millions of years, the organic material turned into fossil fuels. Q: Fossil fuels are made out of what two objects? A:
OPTIONS:
- gases and animals
- plants and water
- soil and animals
- plants and animals
Answer:
plants and animals
