Answer the following question given this paragraph: Wings and feathers are two adaptations for flight that evolved in birds. Both are clearly displayed in the flying gull in Figure below . Wings evolved from the front limbs of a four-legged ancestor. The wings are controlled by large flight muscles in the chest. Feathers also help birds fly. They provide air resistance and lift. In addition, they provide insulation and serve other roles. Q: Birds adapted wings and weathers for flight during what process? A:
OPTIONS:
- migration
- variation
- emergence
- evolution

Answer: evolution

Question: Answer the following question given this paragraph: Reduce, reuse, and recycle. There are steps that you personally can take to conserve our natural resources and reduce waste. The waste that an individual creates is small in proportion to all the waste produced by society. Yet all small contributions, when added up, make a difference. Q: What three rs represent the steps that you personally can take to conserve our natural resources and minimize waste? A:
OPTIONS:
- rinse, reuse, recycle
- remove, reduce, reuse
- reduce, reuse, re-educate
- reduce, reuse, recycle
Answer: reduce, reuse, recycle

input with options: Answer the following question given this paragraph: You can see several examples of people or things in motion in Figure below . You can probably think of many other examples. You know from experience what motion is, so it may seem like a straightforward concept. Motion can also be defined simply, as a change in position. But if you think about examples of motion in more depth, you'll find that the idea of motion is not quite as simple and straightforward as it seems. Q: What can be defined simply, as a change in position? A:
OPTIONS:
- velocity
- gravity
- speed
- motion
output: motion

Q: Answer the following question given this paragraph: Of course, a net external force is needed to cause any acceleration, just as Newton proposed in his second law of motion. So a net external force is needed to cause a centripetal acceleration. In Centripetal Force, we will consider the forces involved in circular motion. PhET Explorations: Ladybug Motion 2D Learn about position, velocity and acceleration vectors. Move the ladybug by setting the position, velocity or acceleration, and see how the vectors change. Choose linear, circular or elliptical motion, and record and playback the motion to analyze the behavior. Q: Of course, a net external force is needed to cause any acceleration, just as newton proposed in his second law of what? A:

OPTIONS:
- land
- gravity
- speed
- motion

A: motion

input: OPTIONS:
