input: OPTIONS:
- coal
- sulpher
- water
- magma Now, answer this question: Answer the following question given this paragraph: Volcanoes may be active, dormant, or extinct. This depends on whether there is the possibility of magma in their magma chambers. Q: Volcanoes are termed active, dormant, or extinct depending on the possibility of the presence of what in chamber structures? A:
A:
output: magma

Answer the following question given this paragraph: To understand the differences between nuclear fission and fusion. Nuclear reactions, like chemical reactions, are accompanied by changes in energy. The energy changes in nuclear reactions, however, are enormous compared with those of even the most energetic chemical reactions. In fact, the energy changes in a typical nuclear reaction are so large that they result in a measurable change of mass. In this section, we describe the relationship between mass and energy in nuclear reactions and show how the seemingly small changes in mass that accompany nuclear reactions result in the release of enormous amounts of energy. Q: The energy changes in what reactions are enormous compared with those of even the most energetic chemical reactions, and they result in a measurable change of mass? A:

OPTIONS:
- molecular reaction
- metabolic reaction
- methane combustion
- nuclear reactions

Answer: nuclear reactions

Problem: OPTIONS:
- galaxies
- stars
- asteroids
- moons
Q: Answer the following question given this paragraph: Saturn's largest moon, Titan, is about one and a half times the size of Earth's moon. Titan is even larger than the planet Mercury. The picture below compares the size of Titan to Earth ( Figure below ). Scientists are very interested in Titan. The moon has an atmosphere that is thought to be like Earth's first atmosphere with nitrogen and methane. This atmosphere was around before life developed on Earth. Like Jupiter's moon, Europa, Titan may have a layer of liquid water under a layer of ice. Scientists now think that there are lakes on Titan's surface. Don't take a dip, though. These lakes contain liquid methane and ethane instead of water! Methane and ethane are compounds found in natural gas. Q: Europa and titan are names of what kind of celestial objects? A:
Answer: moons

Problem:OPTIONS:
- residual energy
- electrostatic energy
- nuclear energy
- kinetic energy

Answer the following question given this paragraph: In this lesson, you read that heating a gas gives its particles more kinetic energy. As a result, its volume or pressure also increases. The opposite happens when a gas is cooled. Q: Heating a gas gives its particles more of what type of energy? A:
****
A: kinetic energy

Answer the following question given this paragraph: Amphibians generally lay large number of eggs. Often, many adults lay eggs in the same place at the same time. This helps to ensure that eggs will be fertilized and at least some of the embryos will survive. Once eggs have been laid, most amphibians are done with their parenting. Q: When does most amphibians' parenting end? A:
OPTIONS:
- after adolescence
- once offspring reach adulthood
- never
- once eggs have been laid
once eggs have been laid

Answer the following question given this paragraph: The epidermis is the outermost layer of the skin. It forms the waterproof, protective wrap over the body's surface. Although the top layer of epidermis is only about as thick as a sheet of paper, it is made up of 25 to 30 layers of cells. The epidermis also contains cells that produce melanin. Melanin is the brownish pigment that gives skin and hair their color. Melanin-producing cells are found in the bottom layer of the epidermis. The epidermis does not have any blood vessels. The lower part of the epidermis receives blood by diffusion from blood vessels of the dermis. Q: What is the outermost layer of the skin? A:
OPTIONS:
- dermis
- nexus
- callus
- epidermis

Answer:
epidermis
