Answer the following question given this paragraph: Kinetic energy is the energy of motion. Any object that is moving possesses kinetic energy. Baseball involves a great deal of kinetic energy. The pitcher throws a ball, imparting kinetic energy to the ball. When the batter swings, the motion of swinging creates kinetic energy in the bat. The collision of the bat with the ball changes the direction and speed of the ball, with the idea of kinetic energy being involved again. Q: What energy is the energy of motion? A:
OPTIONS:
- optimal
- potential
- thermal
- kinetic

Answer: kinetic

Question: Answer the following question given this paragraph: There are other forms of radioactive dating. Rocks, for example, can sometimes be dated based on the decay of 238 U . The decay series for 238 U ends with 206 Pb , so that the ratio of these nuclides in a rock is an indication of how long it has been since the rock solidified. The original composition of the rock, such as the absence of lead, must be known with some confidence. However, as with carbon-14 dating, the technique can be verified by a consistent body of knowledge. Since 238 U has a half-life of solidified about. Q: What is the term for dating a rock based on composition decay? A:
OPTIONS:
- carbon dating
- fuel dating
- safe dating
- radioactive dating
Answer: radioactive dating

input with options: Answer the following question given this paragraph: The evolution of life on Earth wasn't always smooth and steadyfar from it. Living things had to cope with some astounding changes. Giant meteorites struck Earth's surface. Continents drifted and shifted. Ice ages buried the planet in snow and ice for millions of years at a time. At least five times, many, if not most, of Earth's living things went extinct. Extinction occurs when a species completely dies out and no members of the species remain. But life on Earth was persistent. Each time, it came back more numerous and diverse than before. Q: Ice ages, continental drift, and giant meteorites striking earth have caused what phenomenon? A:
OPTIONS:
- gravity
- waves
- depletion
- extinction
output: extinction

Q: Answer the following question given this paragraph: Q: Which acid releases nitrates into soil? A:

OPTIONS:
- citric
- lactic
- sulfuric
- uric

A: uric

input: OPTIONS:
- swamps
- ponds
- sinkholes
- bogs Now, answer this question: Answer the following question given this paragraph: Freshwater marshes and swamps are characterized by slow and steady water flow. Bogs develop in depressions where water flow is low or nonexistent. Bogs usually occur in areas where there is a clay bottom with poor percolation. Percolation is the movement of water through the pores in the soil or rocks. The water found in a bog is stagnant and oxygen depleted because the oxygen that is used during the decomposition of organic matter is not replaced. As the oxygen in the water is depleted, decomposition slows. This leads to organic acids and other acids building up and lowering the pH of the water. At a lower pH, nitrogen becomes unavailable to plants. This creates a challenge for plants because nitrogen is an important limiting resource. Some types of bog plants (such as sundews, pitcher plants, and Venus flytraps) capture insects and extract the nitrogen from their bodies. Bogs have low net primary productivity because the water found in bogs has low levels of nitrogen and oxygen. Q: What develops in depressions where water flow is low or nonexistent? A:
A:
output: bogs

Question: Answer the following question given this paragraph: A scientist is always trying to find the truth and discover new truths. How can you think like a scientist? Thinking like a scientist is based on asking and answering questions. Though you may not know it, you do this all day long. Scientists ask questions, and then make detailed observations to try to ask more specific questions and develop a hypothesis . They may design and perform an experiment to try to answer their question and test their hypothesis. From the results of their experiment, scientists draw conclusions . A conclusion describes what the evidence tells the scientist. Q: Scientists ask questions, and then make detailed observations to try to ask more specific questions, in order to develop what? A:
OPTIONS:
- Tests
- suggests
- theories
- hypothesis
Answer:
hypothesis
