input with options: Answer the following question given this paragraph: Coal is a black or brownish-black rock that burns easily ( Figure below ). Most coal is sedimentary rock. The hardest type of coal, anthracite, is a metamorphic rock. That is because it is exposed to higher temperature and pressure as it forms. Coal is mostly carbon, but some other elements can be found in coal, including sulfur. Q: What element makes up the majority of coal? A:
OPTIONS:
- iron
- lead
- silicon
- carbon
output: carbon

Answer the following question given this paragraph: The frontal lobe is located at the front of the brain, over the eyes. This lobe contains the olfactory bulb, which processes smells. The frontal lobe also contains the motor cortex, which is important for planning and implementing movement. Areas within the motor cortex map to different muscle groups, and there is some organization to this map, as shown in Figure 35.22. For example, the neurons that control movement of the fingers are next to the neurons that control movement of the hand. Neurons in the frontal lobe also control cognitive functions like maintaining attention, speech, and decisionmaking. Studies of humans who have damaged their frontal lobes show that parts of this area are involved in personality, socialization, and assessing risk. Q: What is the bulb called in the frontal lobe that processes smells? A:

OPTIONS:
- peripheral bulb
- auditory bulb
- sensory bulb
- olfactory bulb

Answer: olfactory bulb

Q: Answer the following question given this paragraph: How high or low a sound seems to a listener is its pitch . Pitch, in turn, depends on the frequency of sound waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. High-pitched sounds, like the sounds of the piccolo in the Figure below , have high-frequency waves. Low-pitched sounds, like the sounds of the tuba Figure below , have low-frequency waves. For a video demonstration of frequency and pitch, go to this URL: http://www. youtube. com/watch?v=irqfGYD2UKw. Q: Dependent on the frequency of sound waves, what term described how high or low a sound seems to a listener? A:

OPTIONS:
- curve
- wavelength
- direction
- pitch

A:
pitch
