Answer the following question given this paragraph: Nuclear fission is the splitting of the nucleus of an atom into two smaller nuclei. This releases a great deal of energy. Nuclear power plants use the energy from nuclear fission to generate electricity. Q: What is it called when the nucleus of an atom splits into two smaller nuclei? A:

OPTIONS:
- complex fission
- cell division
- nuclear fusion
- nuclear fission

Answer: nuclear fission

Problem: OPTIONS:
- platinum
- silver
- copper
- gold

Answer: gold

Problem:OPTIONS:
- heat
- light
- matter
- electricity

Answer the following question given this paragraph: Figure 8.39 Molecular orbitals in solids are so closely spaced that they are described as bands. The valence band is lower in energy and the conduction band is higher in energy. The type of solid is determined by the size of the "band gap" between the valence and conduction bands. Only a very small amount of energy is required to move electrons from the valance band to the conduction band in a conductor, and so they conduct electricity well. In an insulator, the band gap is large, so that very few electrons move, and they are poor conductors of electricity. Semiconductors are in between: they conduct electricity better than insulators, but not as well as conductors. In order to conduct electricity, electrons must move from the filled valence band to the empty conduction band where they can move throughout the solid. The size of the band gap, or the energy difference between the top of the valence band and the bottom of the conduction band, determines how easy it is to move electrons between the bands. Only a small amount of energy is required in a conductor because the band gap is very small. This small energy difference is "easy" to overcome, so they are good conductors of electricity. In an insulator, the band gap is so "large" that very few electrons move into the conduction band; as a result, insulators are poor conductors of electricity. Semiconductors conduct electricity when "moderate" amounts of energy are provided to move electrons out of the valence band and into the conduction band. Semiconductors, such as silicon, are found in many electronics. Semiconductors are used in devices such as computers, smartphones, and solar cells. Solar cells produce electricity when light provides the energy to move electrons out of the valence band. The electricity that is generated may then be used to power a light or tool, or it can be stored for later use by charging a battery. As of December 2014, up to 46% of the energy in sunlight could be converted into electricity using solar cells. Q: In order to conduct what, electrons must move from the filled valence band to the empty conduction band where they can move throughout the solid? A:
****
A: electricity

Answer the following question given this paragraph: Tides are not unique to Earth but occur in many astronomical systems. The most extreme tides occur where the gravitational force is the strongest and varies most rapidly, such as near black holes (see Figure 6.26). A few likely candidates for black holes have been observed in our galaxy. These have masses greater than the Sun but have diameters only a few kilometers across. The tidal forces near them are so great that they can actually tear matter from a companion star. Q: The tidal forces near what celestial phenomena are so great they can actually tear matter from a companion star? A:
OPTIONS:
- dwarf star
- large holes
- wormholes
- black holes
black holes

OPTIONS:
- pupal
- larval
- adult
- embryonic

Answer: embryonic

input with options: Answer the following question given this paragraph: The nucleus is a small, dense region at the center of the atom. It consists of positive protons and neutral neutrons, so it has an overall positive charge. Q: What is the small, dense region at the center of the atom that consists of positive protons and neutral neutrons? A:
OPTIONS:
- proton
- electron
- photon
- nucleus
output:
nucleus
