Question: Answer the following question given this paragraph: The amount of reactants and products do not have to be equal. However, after equilibrium is attained, the amounts of reactants and products will be constant. Q: In a chemical reaction, the amounts of reactants and products will be constant when what state is attained? A:
OPTIONS:
- saturation
- peak
- homogeneity
- equilibrium
Answer: equilibrium

input with options: Answer the following question given this paragraph: Most of the world's largest mountains form as plates collide at convergent plate boundaries. Continents are too buoyant to get pushed down into the mantle. So when the plates smash together, the crust crumples upwards. This creates mountains. Folding and faulting in these collision zones makes the crust thicker. Q: Why are continents unable to be pushed down into the mantle by plate boundaries? A:
OPTIONS:
- gravity
- surface tension
- density
- buoyancy
output: buoyancy

Q: Answer the following question given this paragraph: The age-sex structure of a population is the number of individuals of each sex and age in the population. Age-sex structure influences population growth. It is represented by a population pyramid. The number of survivors at each age is plotted on a survivorship curve. Q: What helps represent age-sex structure of the population? A:

OPTIONS:
- habitat chart
- density graph
- biome model
- population pyramid

A: population pyramid

input: OPTIONS:
- plutonium accelerators
- nitrogen accelerators
- nuclear reactors
- particle accelerators Now, answer this question: Answer the following question given this paragraph: Particle accelerators simulate nuclear fusion in stars. Q: How can nuclear fusion in stars be simulated? A:
A:
output: particle accelerators

Answer the following question given this paragraph: Many people think that any idea that is completely accepted in science is a law. But that is not true. In science, a law is something that always applies under the same conditions. A law explains a fairly simple phenomenon. A theory is much more complex: it tells you why something happens. A law only tells you that it happens. For example, if you hold something above the ground and let go, it will fall. This phenomenon is recognized by the law of gravity ( Figure below ). Some people say that evolution is "just a theory. " But for a complex explanation like evolution, theory is the right word. Q: In science, what do you call something that always applies under the same conditions? A:

OPTIONS:
- theory
- hypothesis
- scientific method
- scientific law

Answer: scientific law

Q: Answer the following question given this paragraph: Comets are small, icy objects that orbit the Sun in very elliptical orbits. When they are close to the Sun, they form comas and tails, which glow and make the comet more visible. Q: What types of orbits do comets usually have? A:

OPTIONS:
- vertical
- convex
- spectral
- elliptical

A:
elliptical
