input with options: Answer the following question given this paragraph: Plant Organ Systems In plants, just as in animals, similar cells working together form a tissue. When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems. Vascular plants have two distinct organ systems: a shoot system, and a root system. The shoot system consists of two portions: the vegetative (nonreproductive) parts of the plant, such as the leaves and the stems, and the reproductive parts of the plant, which include flowers and fruits. The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis. The root system, which supports the plants and absorbs water and minerals, is usually underground. Figure 30.2 shows the organ systems of a typical plant. Q: When different types of tissues work together to perform a unique function, what do they form? A:
OPTIONS:
- organs
- Brian
- produce
- organ
output: organ

Q: Answer the following question given this paragraph: Evaporation occurs when water on the surface changes to water vapor. The sun heats the water and gives water molecules enough energy to escape into the atmosphere. Q: What occurs when water on the surface changes to water vapor? A:

OPTIONS:
- oxidation
- photosynthesis
- condensation
- evaporation

A: evaporation

input: OPTIONS:
- erosion
- volcanoes
- storms
- earthquakes Now, answer this question: Answer the following question given this paragraph: When an earthquake will occur is much more difficult to predict. Stress on a fault builds up at the same rate over time. So earthquakes should occur at regular intervals. But, so far, scientists cannot predict when quakes will occur even to within a few years. Around Parkfield, California, an earthquake of magnitude 6.0 or higher occurs about every 22 years. So seismologists predicted that one would strike in 1993. But that quake came in 200411 years late ( Figure below ). Q: Stress building up at the same rate over time at a fault causes what phenomenon? A:
A:
output: earthquakes

Answer the following question given this paragraph: Distillation is an effective method to separate mixtures comprised of two or more pure liquids. Distillation is a purification process in which the components of a liquid mixture are vaporized (transformed from liquid to gas) and then condensed (transformed from gas back to liquid) and isolated. In a simple distillation, a mixture is gradually heated. The solution with the lowest boiling point will change into a gas first. This gas, or vapor, then passes through a cooled tube (a condenser) where it condenses back into its liquid state. This condensed liquid is called the distillate. Figure below illustrates this. Q: Distillation is an effective method to separate mixtures comprised of two or more what? A:

OPTIONS:
- solutes
- ionic compounds
- elements
- pure liquids

Answer: pure liquids

Problem: OPTIONS:
- condensation
- solidification
- vaporization
- sublimation
Q: Answer the following question given this paragraph: The process in which a solid changes directly to a gas is called sublimation . It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Dry ice (solid carbon dioxide, CO 2 ) is an example of a solid that undergoes sublimation. Figure below shows a chunk of dry ice changing directly to carbon dioxide gas. Sometimes snow undergoes sublimation as well. This is most likely to occur on sunny winter days when the air is very dry. What gas does snow become?. Q: What is the process in which a solid changes directly to a gas called? A:
Answer: sublimation

Answer the following question given this paragraph: A seamount is a volcanic mountain on the ocean floor. Seamounts that rise above the water surface are known as islands. There are many seamounts dotting the seafloor. Q: What are seamounts that rise above the water surface called? A:

OPTIONS:
- sandbars
- coasts
- reefs
- islands

Answer:
islands
