Answer the following question given this paragraph: Organs of the GI tract are covered by muscles that contract to keep food moving along. A series of involuntary muscle contractions moves rapidly along the tract, like a wave travelling through a spring toy. The muscle contractions are called peristalsis. The diagram in Figure below shows how peristalsis works. Q: What do the muscles of the gastrointestinal tract do? A:
OPTIONS:
- break down food
- secrete stomach acid
- stop digestion
- keep food moving
keep food moving

Answer the following question given this paragraph: Quantities in science may be very large or very small. This usually requires many zeroes to the left or right of the decimal point. Such numbers can be hard to read and write accurately. That's where scientific notation comes in. Scientific notation is a way of writing very large or small numbers that uses exponents. Numbers are written in this format:. Q: What term is defined as a way of writing very large or small numbers that uses exponents? A:
OPTIONS:
- certain notation
- exponential notation
- quadratic notation
- scientific notation

Answer: scientific notation

Question: Answer the following question given this paragraph: When compounds are synthesized, they often have contaminating materials mixed in with them. The process of recrystallization can be used to remove these impurities. The crystals are dissolved in a hot solvent, forming a solution. When the solvent is cooled the compound is no longer as soluble and will precipitate out of solution, leaving other materials still dissolved. Q: Recrystallization is a process that can remove what, which result when compounds are synthesized? A:
OPTIONS:
- chemicals
- substances
- minerals
- contaminants
Answer: contaminants

input with options: Answer the following question given this paragraph: All matter consists of atoms, which cannot be further subdivided into smaller particles. Q: What does all matter consist of? A:
OPTIONS:
- carbon
- helium
- oxygen
- atoms
output: atoms

Q: Answer the following question given this paragraph: Alpha, beta, and gamma emissions have different abilities to penetrate matter. The relatively large alpha particle is easily stopped by matter (although it may impart a significant amount of energy to the matter it contacts). Beta particles penetrate slightly into matter, perhaps a few centimeters at most. Gamma rays can penetrate deeply into matter and can impart a large amount of energy into the surrounding. Q: Alpha, beta, and gamma emissions are associated with what kind of energy? A:

OPTIONS:
- kinetic
- electrical
- potential
- radiation

A: radiation

Answer the following question given this paragraph: The rocks in this photo of the Grand Canyon are all sedimentary. Hard rocks that are resistant to weathering form cliffs. Softer rocks that weather more easily form slopes. Q: In places like the grand canyon, hard rocks that are resistant to weathering form what, while softer rocks that weather more easily form slopes? A:
OPTIONS:
- valleys
- peaks
- crevasses
- cliffs
cliffs
