Answer the following question given this paragraph: Emphysema is a disease in which the walls of the alveoli break down so less gas can be exchanged by the lungs. The main symptom of emphysema is shortness of breath. The damage to the alveoli is usually caused by smoking and is permanent. Q: What disease associated with smoking involves breakdown of walls of the alveoli, resulting in less gas exchange by the lungs? A:

OPTIONS:
- leukemia
- cancer
- pneumonia
- emphysema

Answer: emphysema

Answer the following question given this paragraph: In unsaturated fatty acids, there is at least one double bond between carbon atoms. As a result, some carbons are not bonded to as many hydrogen atoms as possible. Unsaturated fatty acids are found in oils. Oils are liquid lipids that plants use to store energy. Q: Oils are liquid lipids that plants use for storage of what? A:
OPTIONS:
- fat
- glucose
- oxygen

energy

Answer the following question given this paragraph: Oil comes out of the ground as crude oil. Crude oil is a mixture of many different hydrocarbons. Oil is separated into different compounds at an oil refinery ( Figure above ). This is done by heating the oil. Each hydrocarbon compound in crude oil boils at a different temperature. We get gasoline, diesel, and heating oil, plus waxes, plastics, and fertilizers from crude oil. Q: Crude oil is a mixture of different types of what? A:
OPTIONS:
- contaminants
- fats
- greenhouse gases
- hydrocarbons

Answer: hydrocarbons

input with options: Answer the following question given this paragraph: The time interval required for one complete wave to pass a point is called the period . During the period of the wave, an entire wavelength from one crest to the next crest passes a position. The number of waves that pass a single position in one second is called the frequency . The period of a wave and its frequency are reciprocals of each other. Q: What is the time interval required for one complete wave to pass a point called? A:
OPTIONS:
- cycle
- minute
- half-life
- period
output:
period
