Problem:OPTIONS:
- visible energy flow
- coolant energy flow
- spectral energy flow
- thermal energy flow

Answer the following question given this paragraph: A refrigerator must do work to reverse the normal direction of thermal energy flow. Work involves the use of force to move something, and doing work takes energy. In a refrigerator, the energy is usually provided by electricity. You can read in detail in the Figure below how a refrigerator does its work. For an animation of how a refrigerator works, go to this URL: http://www. chemistry. wustl. edu/~edudev/LabTutorials/CourseTutorials/LabTutorials/Thermochem/fridge_movie. html. Q: A refrigerator must do work to reverse the normal direction of what? A:
****
A: thermal energy flow

Answer the following question given this paragraph: Ohm's law may be easier to understand with an analogy. Current flowing through a wire is like water flowing through a hose. Increasing voltage with a higher-volt battery increases the current. This is like opening the tap wider so more water flows through the hose. Increasing resistance reduces the current. This is like stepping on the hose so less water can flow through it. If you still aren't sure about the relationships among current, voltage, and resistance, watch the video at this URL: http://www. youtube. com/watch?v=KvVTh3ak5dQ. Q: Increasing voltage with a higher-volt battery does what to the current? A:
OPTIONS:
- blocks it
- stops it
- decreases it
- increases it
increases it

Answer the following question given this paragraph: Segmentation evolved next. Segmentation is the division of the body into multiple parts, or segments. Both the earthworm (Phylum Annelida) in Figure below and ant (Phylum Arthropoda) in Figure below have segmented bodies. The earthworm has many small segments. The ant has three larger segments. Segmentation increases an animal's flexibility. It allows a wider range of motion. Different segments can also be specialized for different functions. All modern annelids and arthropods are segmented. Q: Earthworms and ants possess what type of bodies, which means division into multiple parts? A:
OPTIONS:
- elongated
- truncated
- elliptical
- segmented

Answer: segmented

Question: Answer the following question given this paragraph: Bioluminescent organisms include jellyfish and fireflies. Jellyfish give off visible light to startle predators. Fireflies give off visible light to attract mates. Q: What do jellyfish use to startle predators? A:
OPTIONS:
- black light
- bicellular light
- harsh light
- visible light
Answer: visible light

input with options: Answer the following question given this paragraph: 7. Compare and contrast the ecosystem concepts of niche and habitat. Q: Niche and habitat are concepts related to what broader term? A:
OPTIONS:
- population
- biome
- community
- ecosystem
output: ecosystem

Problem: OPTIONS:
- clean
- calcareous
- limestones
- bituminous
Q: Answer the following question given this paragraph: Coal has different grades. Bituminous coal forms at lower temperatures. It contains a lot of sulfur. When it is burned, it causes a lot of pollution. Anthracite coal forms under higher temperatures. This drives off the sulfur, and the coal burns more cleanly. Q: What type of coal is formed at lower temperatures? A:
Answer:
bituminous
