Question: Answer the following question given this paragraph: To harness water power, a stream must be dammed. Narrow valleys are the best for dams. While sitting in the reservoir behind the dam, the water has potential energy. Water is allowed to flow downhill into a large turbine. While flowing downhill, the water has kinetic energy. Kinetic energy makes the turbine spin. The turbine is connected to a generator, which makes electricity. Q: Water is allowed to flow downhill into a large turbine to harness power. what helps the turbine spin? A:
OPTIONS:
- residual energy
- electrostatic energy
- polar energy
- kinetic energy
Answer: kinetic energy

input with options: Answer the following question given this paragraph: Annelids are segmented worms such as earthworms and leeches. Annelids have a coelom, closed circulatory system, excretory system, and complete digestive system. They also have a brain. Earthworms are important deposit feeders that help form and enrich soil. Leeches are either predators or parasites. Parasitic leeches feed off the blood of vertebrate hosts. Q: Parasitic leeches feed off of what? A:
OPTIONS:
- brain
- tissue
- tumor
- blood
output: blood

Q: Answer the following question given this paragraph: We see an opaque object, such as the apple in Figure below , because it reflects some wavelengths of visible light. The wavelengths that are reflected determine the color that the object appears. For example, the apple in the figure appears red because it reflects red light and absorbs light of other wavelengths. We see a transparent or translucent object, such as the bottle in Figure below , because it transmits light. The wavelength of the transmitted light determines the color that the object appears. For example, the bottle in the figure appears blue because it transmits blue light. Q: The color of an object is determined by the what of it's reflected light? A:

OPTIONS:
- luminosity
- variation
- absorption
- wavelength

A: wavelength

input: OPTIONS:
- socket
- tendons
- collagen
- cartilage Now, answer this question: Answer the following question given this paragraph: Partly movable joints allow only very limited movement. Bones at these joints are held in place by cartilage. The ribs and sternum are connected by partly movable joints. Q: What are the bones in partly movable joints held in place by? A:
A:
output: cartilage

Answer the following question given this paragraph: Cooling and crystallization. Deep within the Earth, temperatures can get hot enough to create magma. As magma cools, crystals grow, forming an igneous rock. The crystals grow larger if the magma cools slowly, as it does if it remains deep within the Earth. If the magma cools quickly, the crystals will be very small. When crystals form from magma it is called crystallization . Q: What is it called when crystals form from magma? A:

OPTIONS:
- sedimentation
- transpiration
- vulcanism
- crystallization

Answer: crystallization

Q: Answer the following question given this paragraph: All chemical reactions need energy to get started. Even reactions that release energy need a boost of energy in order to begin. The energy needed to start a chemical reaction is called activation energy . Activation energy is like the push a child needs to start going down a playground slide. The push gives the child enough energy to start moving, but once she starts, she keeps moving without being pushed again. Activation energy is illustrated in Figure below . Q: What is the amount of energy required to begin a chemical reaction known as? A:

OPTIONS:
- decomposition energy
- reaction energy
- positive energy
- activation energy

A:
activation energy
