input with options: Answer the following question given this paragraph: Longitudinal waves, like sound waves, have compression and rarefaction zones. The compression zones are where, for example in a sound wave traveling through air, the air molecules are densely packed. The rarefaction zones are areas where the air molecules are loosely packed, like a vacuum zone. Us teachers will often draw longitudinal waves as transverse waves, but remember the difference. Q: What is the opposite of rarefaction zones, where air molecules in waves are loosely packed? A:
OPTIONS:
- molecules zones
- pressure wave
- measurements zones
- compression zones
output: compression zones

Q: Answer the following question given this paragraph: In trees, some of the epidermal tissue is replaced by bark. Bark is a combination of tissues that provides a tough, woody external covering on the stems of trees. The inner part of bark is alive and growing; the outer part is dead and provides strength, support, and protection. Q: What is the combination of tissues that provides a tough, woody external covering on the stems of trees called? A:

OPTIONS:
- cuticle
- scale
- epidermis
- bark

A: bark

input: OPTIONS:
- bloodstream
- estrogen
- methane
- testosterone Now, answer this question: Answer the following question given this paragraph: Another obvious change that occurs during puberty is rapid growth. This is called the adolescent growth spurt . In boys, it is controlled by testosterone. The rate of growth usually starts to increase relatively early in puberty. At its peak rate, growth in height is about 10 centimeters (almost 4 inches) per year in the average male. Growth generally remains rapid for several years. Growth and development of muscles occur toward the end of the growth spurt in height. Muscles may continue to develop and gain strength after growth in height is finished. Q: What drives puberty in male humans? A:
A:
output: testosterone

Answer the following question given this paragraph: Some volcanoes form over active hot spots . Scientists count about 50 hot spots on the Earth. Hot spots may be in the middle of a tectonic plate. Hot spots lie directly above a column of hot rock called a mantle plume . Mantle plumes continuously bring magma up from the mantle towards the crust ( Figure below ). Q: What substance comes toward earth's crust through mantle plumes? A:

OPTIONS:
- rocks
- water
- gas
- magma

Answer: magma

Problem: OPTIONS:
- migration
- circulation
- procreation
- communication
Q: Answer the following question given this paragraph: For individuals to cooperate, they need to communicate . Animals can communicate with sounds, chemicals, or visual cues. For example, to communicate with sounds, birds sing and frogs croak. Both may be communicating that they are good mates. Ants communicate with chemicals called pheromones . For example, they use the chemicals to mark trails to food sources so other ants can find them. Male dogs use pheromones in urine to mark their territory. They are "telling" other dogs to stay out of their yard. You can see several examples of visual communication in Figure below . Q: Sounds, chemicals, and visual cues are examples of what between animals? A:
Answer: communication

Answer the following question given this paragraph: Temperature is the average kinetic energy of the molecules. Q: Temperature can be defined as the average of what type of energy of the molecules? A:

OPTIONS:
- magnetic
- optical
- potential
- kinetic

Answer:
kinetic
