Question: Answer the following question given this paragraph: The cardiovascular system is the system of organs that delivers blood to all the cells of the body. It's like the body's lifeline. Without the cardiovascular system circulating your blood, you couldn't survive. Q: What system of organs delivers blood to all cells of the body? A:
OPTIONS:
- gastrointestinal
- respiratory
- integumentary
- cardiovascular
Answer: cardiovascular

input with options: Answer the following question given this paragraph: Electromagnetic waves may also be absorbed by matter and converted to other forms of energy. Microwaves are a familiar example. When microwaves strike food in a microwave oven, they are absorbed and converted to thermal energy, which heats the food. Q: Microwaves are converted into what kind of energy in a microwave oven? A:
OPTIONS:
- solar energy
- mechanical energy
- light energy
- thermal energy
output: thermal energy

Q: Answer the following question given this paragraph: The axe head and the doorstop are both examples of a wedge, a type of simple machine. Q: An axe head and a doorstop are types of what simple machine? A:

OPTIONS:
- pulley
- blade
- lever
- wedge

A: wedge

input: OPTIONS:
- storm
- water mass
- weather
- air mass Now, answer this question: Answer the following question given this paragraph: The direction of prevailing winds determines which type of air mass usually moves over an area. For example, a west wind might bring warm moist air from over an ocean. An east wind might bring cold dry air from over a mountain range. Which wind prevails has a big effect on the climate. What if the prevailing winds are westerlies? The westerlies blow from nearer the Equator to farther from the Equator. How would they affect the climate?. Q: The direction of prevailing winds determines the type of what that usually moves over an area? A:
A:
output: air mass

Answer the following question given this paragraph: The inertia of an object depends on its mass. Objects with greater mass also have greater inertia. Think how hard it would be to push a big box full of books, like the one in Figure below . Then think how easy it would be to push the box if it was empty. The full box is harder to move because it has greater mass and therefore greater inertia. Q: What property increases as an object's mass increases, making a full box harder to push than an empty one? A:

OPTIONS:
- weight
- gravity
- magnetism
- inertia

Answer: inertia

Q: Answer the following question given this paragraph: Some predator species play a special role in their community. They are called keystone species. When the population size of a keystone species changes, the populations of many other species are affected. Prairie dogs, pictured in Figure below , are an example of a keystone species. Their numbers affect most of the other species in their community. Prairie dog actions improve the quality of soil and water for plants, upon which most other species in the community depend. Q: What do you call a predator species that affects other species' populations when its own population size changes? A:

OPTIONS:
- paradox species
- symbiotic species
- complement species
- keystone species

A:
keystone species
