Question: Answer the following question given this paragraph: A: Variables might include factors relating to the ramp or to the object. An example of a variable relating to the ramp is its steepness. An example of a variable relating to the object is the way it movesit might roll or slide down the ramp. Either of these variables could be manipulated by the researcher, so you could choose one of them for your manipulated variable. Q: An example of a variable relating to the ramp is its what? A:
OPTIONS:
- color
- mass
- weight
- steepness
Answer: steepness

input with options: Answer the following question given this paragraph: New land can be created by volcanic eruptions. Q: New land can be created when what happens to a volcano? A:
OPTIONS:
- it evolves
- it dies
- it stays dormant
- it erupts
output: it erupts

Q: Answer the following question given this paragraph: Cinder cones are the smallest and most common type of volcano. Cinder cones have steep sides like composite volcanoes. But they are much smaller, rarely reaching even 300 meters in height. Cinder cones usually have a crater at the summit. Cinder cones are composed of small fragments of rock, called cinders. The cinders are piled on top of one another. The cinders can be mafic, intermediate, or felsic in composition. These volcanoes usually do not produce streams of lava. Cinder cones often form near larger volcanoes. Most composite and shield volcanoes have nearby cinder cones. Q: What is the most common type of volcano? A:

OPTIONS:
- geyser
- block cone
- flat
- cinder cone

A: cinder cone

input: OPTIONS:
- light
- electricity
- enzymes
- energy Now, answer this question: Answer the following question given this paragraph: Chemical reactions either require energy or release energy. The amount of energy needed or released depends upon the structure of the molecules that are involved in the reaction. Some reactions need to be heated for long periods of time in order for change to take place. Other reactions release energy, allowing heat to be given off to the surroundings. Q: Chemical reactions either require or release what? A:
A:
output: energy

Answer the following question given this paragraph: Half-Life Why use a term like half-life rather than lifetime? The answer can be found by examining Figure 31.21, which shows how the number of radioactive nuclei in a sample decreases with time. The time in which half of the original number of nuclei decay is defined as the half-life, t 1 / 2 . Half of the remaining nuclei decay in the next half-life. Further, half of that amount decays in the following half-life. Therefore, the number of radioactive nuclei decreases from. Q: What term means the time in which half of the original number of radioactive nuclei in a sample decay? A:

OPTIONS:
- reduced life
- quarter-life
- partial-life
- half-life

Answer: half-life

Q: Answer the following question given this paragraph: The nuclei of radioisotopes are unstable, so they constantly decay and emit radiation. Q: The nuclei of radioisotopes are unstable, so they constantly decay and emit what? A:

OPTIONS:
- moisture
- acid
- chemicals
- radiation

A:
radiation
