input: OPTIONS:
- booms
- stones
- shoots
- projectiles Now, answer this question: Answer the following question given this paragraph: Objects that are launched into the air are called projectiles . The path followed by a projectile in motion is called a trajectory . The image of the snowboarder in the chapter introduction showed his trajectory; every object has a trajectory even when we cannot see it. Projectile motion , or the object's trajectory, is described in terms of position, velocity, and acceleration. Even with only an object's current location, velocity, and acceleration, we can calculate when and where the object will land. Our knowledge that perpendicular components of vectors do not affect each other allow us to easily analyze the motion of projectiles. Q: What are objects that are launched into the air called? A:
A:
output: projectiles

Answer the following question given this paragraph: Gene transcription is controlled by regulatory proteins that bind to regulatory elements on DNA. The proteins usually either activate or repress transcription. Q: What is controlled by regulatory proteins that bind to regulatory elements on dna? A:

OPTIONS:
- amino acids
- mRNA
- substance transcription
- gene transcription

Answer: gene transcription

Problem: OPTIONS:
- liquid bond
- covalent bond
- galactic bond
- metallic bond
Q: Answer the following question given this paragraph: A metallic bond is the force of attraction between a positive metal ion and the valence electrons that surround itboth its own valence electrons and those of other ions of the same metal. The ions and electrons form a lattice-like structure. Only metals, such as the copper pictured in the Figure below , form metallic bonds. Q: What is the force of attraction between a positive metal ion and valence electrons? A:
Answer: metallic bond
