input with options: Answer the following question given this paragraph: Steam rises from the cooling towers of this nuclear power plant. The steam is only harmless water vapor. Unlike a power plant that burns fossil fuel, a nuclear power plant doesn't release pollution into the air. That's because a nuclear power plant produces power by nuclear fission, a type of nuclear reaction. Q: What is harmless water vapor, for a powerplant? A:
OPTIONS:
- wind
- plasma
- fog
- steam
output: steam

Q: Answer the following question given this paragraph: An ionic bond is the force of attraction that holds together positive and negative ions. It forms when atoms of a metallic element give up electrons to atoms of a nonmetallic element. The Figure below shows how this happens. Q: What is the force of attraction that holds together positive and negative ions? A:

OPTIONS:
- electron bond
- magnetic bond
- integral bond
- ionic bond

A: ionic bond

Answer the following question given this paragraph: Blood pressure occurs when circulating blood puts pressure on the walls of blood vessels. Q: What is caused when circulating blood puts pressure on the walls of blood vessels? A:

OPTIONS:
- aneurysm
- atherosclerosis
- high cholesterol
- blood pressure

Answer: blood pressure

Problem: OPTIONS:
- pipe joint
- toe joint
- frame joint
- hinge joint
Q: Answer the following question given this paragraph: Hinge Joints In hinge joints, the slightly rounded end of one bone fits into the slightly hollow end of the other bone. In this way, one bone moves while the other remains stationary, like the hinge of a door. The elbow is an example of a hinge joint. The knee is sometimes classified as a modified hinge joint (Figure 38.28). Q: The elbow is an example of a what type of joint? A:
Answer: hinge joint

Answer the following question given this paragraph: Human skin color is primarily due to the presence of the pigment melanin in the skin. Melanin is not a protein, but it is the product of a biosynthetic pathway. Skin color is a polygenic trait and obviously demonstrates quantitative characteristics. A number of genes factor into determining a person's natural skin color, so modifying only one of those genes changes the color only slightly. It is currently thought that at least three separately inherited genes contribute to skin pigmentation. Let's call these three genes A, B, and C. A, B, and C are incompletely dominant to a, b, and c, with A, B, and C each contributing a "unit of darkness" to the phenotype. Therefore an AABBCC individual is very dark, darker than an AaBbCc individual, and much darker than a aabbcc individual. A person may have as many as 6 "dark units" to as few as no "dark units," and any combination in between. This will result in a phenotypic spectrum of color gradation. When graphed, a phenotypic spectrum usually results in a bell-shaped curve, with extreme phenotypes on both ends and more common phenotypes in the center of the curve. Q: Human skin color is primarily due to the presence of what pigment in the skin? A:

OPTIONS:
- tannin
- melatonin
- cytoplasm
- melanin

Answer:
melanin
