Answer the following question given this paragraph: Atherosclerosis normally begins in late childhood and is typically found in most major arteries. It does not usually have any early symptoms. Causes of atherosclerosis include a high-fat diet, high cholesterol, smoking, obesity, and diabetes. Atherosclerosis becomes a threat to health when the plaque buildup prevents blood circulation in the heart or the brain. A blocked blood vessel in the heart can cause a heart attack. Blockage of the circulation in the brain can cause a stroke. Q: What can happen if there is a blockage in circulation to the brain? Choices: - memory - automation - hydration - stroke A:
stroke
Answer the following question given this paragraph: To this point, we have examined the relationships between any two of the variables of , , and , while the third variable is held constant. However, situations arise where all three variables change. The combined gas law expresses the relationship between the pressure, volume, and absolute temperature of a fixed amount of gas. For a combined gas law problem, only the amount of gas is held constant. Q: The combined gas law involves three properties of a gas - volume, absolute temperature, and what? Choices: - power - time - direction - pressure A:
pressure
Q: Answer the following question given this paragraph: When two continental plates converge, they smash together and create mountains. Q: The converging of continental plates can form what kind of geological feature? Choices: - plains - streams - shores - mountains A:
A: mountains
Question: Answer the following question given this paragraph: There are two main types of air pollutants: primary and secondary. Most air pollutants come from burning fossil fuels. Some come from burning forests. Some are due to the evaporation of chemicals. Q: What are the two main types of air pollutants? Choices: - a and b - new and old - good and bad - primary and secondary A:
Answer: primary and secondary

Answer the following question given this paragraph: As you know, density is defined as the mass per unit volume of a substance. Since gases all occupy the same volume on a per mole basis, the density of a particular gas is dependent on its molar mass. A gas with a small molar mass will have a lower density than a gas with a large molar mass. Gas densities are typically reported in g/L. Gas density can be calculated from molar mass and molar volume. Q: What is defined as the mass per unit volume of a substance? Choices: - weight - diameter - height - density A:
**Answer**
density
Q: Answer the following question given this paragraph: Joints may be immovable, partly movable, or movable. Types of movable joints include ball-and-socket, hinge, and pivot joints. Q: What type of joint are ball-and-socket, hinge, and pivot examples of? Choices: - retractable - artificial - fixed - movable A:
A: movable
