Answer the following question given this paragraph: Both fluorine and lithium are highly reactive elements because of their number of valence electrons. Fluorine will readily gain one electron and lithium will just as readily give up one electron to become more stable. In fact, lithium and fluorine will react together as shown in the Figure below . When the two elements react, lithium transfers its one "extra" electron to fluorine. Q: Both fluorine and lithium are highly reactive elements because of their number of what? A:
OPTIONS:
- shell electrons
- positrons
- covalence electrons
- valence electrons
valence electrons

Answer the following question given this paragraph: Animal behavior is any way that animals interact with each other or their environment. Many animal behaviors promote fitness by increasing the chances of surviving or reproducing. If such behaviors are controlled by genes, they evolve by natural selection. Q: What term is used to describe the way that animals interact with each other or their environment? A:
OPTIONS:
- animal magnetism
- animal decline
- animal range
- animal behavior

Answer: animal behavior

Question: Answer the following question given this paragraph: The rate of the expansion of the universe is increasing. The cause of this increase is unknown; one possible explanation involves a new form of energy called dark energy. Q: What is happening to the rate of the expansion of the universe? A:
OPTIONS:
- it is decreasing
- it is stable
- it is unknown
- it is increasing
Answer: it is increasing

input with options: Answer the following question given this paragraph: All substances are made of atoms. Atoms are the smallest particles of matter. They cannot be divided into smaller particles, created, or destroyed. Q: What are considered to be the smallest particles of matter? A:
OPTIONS:
- cells
- ions
- molecules
- atoms
output: atoms

Q: Answer the following question given this paragraph: Centripetal force is, simply, the force that causes centripetal acceleration. Objects that move in uniform circular motion all have an acceleration toward the center of the circle and therefore, they must also suffer a force toward the center of the circle. That force is the centripetal force. For orbiting satellites, such as the moon orbiting the earth or the earth orbiting the sun, the centripetal force is produced by gravity. When an Olympic hammer thrower whirls a massive ball on a chain, the centripetal force is created by the athlete and transmitted by the chain. Q: What produces the centripetal force to keep the earth orbiting the sun? A:

OPTIONS:
- heat
- motion
- weight
- gravity

A: gravity

Answer the following question given this paragraph: Bile salts are secreted into the small intestine to aid in the digestion of fats. Q: What type of salts are secreted into the small intestine to aid in the digestion of fats? A:
OPTIONS:
- zinc
- Table Salt
- sodium
- bile
bile
