Q: Answer the following question given this paragraph: The Sun and many other light sources produce waves that are randomly polarized (see Figure 27.39). Such light is said to be unpolarized because it is composed of many waves with all possible directions of polarization. Polaroid materials, invented by the founder of Polaroid Corporation, Edwin Land, act as a polarizing slit for light, allowing only polarization in one direction to pass through. Polarizing filters are composed of long molecules aligned in one direction. Thinking of the molecules as many slits, analogous to those for the oscillating ropes, we can understand why only light with a specific polarization can get through. The axis of a polarizing filter is the direction along which the filter passes the electric field of an EM wave (see Figure 27.40). Q: The sun and many other light sources produce waves that are randomly this? A:
Answer: polarized

Answer the following question given this paragraph: Another example is carbon dioxide. This gas is produced from a variety of reactions, often by the burning of materials. The structure of the gas consists of one atom of carbon and two atoms of oxygen. Carbon dioxide production is of interest in many areas, from the amount we breather out to the amount of the gas produced by burning wood or fossil fuels. By knowing the exact composition of carbon dioxide, we can make predictions as to the effects of different chemical processes. Q: The structure of the gas carbon dioxide consists of one atom of carbon and two atoms of what? A:
OPTIONS:
- sulfur
- methane
- Helium
- oxygen
oxygen

Answer the following question given this paragraph: In this lesson, you learned some of the ways that humans differ from other mammals. For example, humans have a larger and more complex brain than other mammals. That's why they are also the most intelligent mammals. The next chapter introduces the biology of the human animal. Q: What mammal is the most intelligent? A:
OPTIONS:
- dog
- monkey
- lion
- humans

Answer: humans

Question: Answer the following question given this paragraph: The pineal gland is a tiny gland located at the base of the brain. It secretes the hormone melatonin. This hormone controls sleep-wake cycles and several other processes. Q: What gland is located at the base of the brain and secretes the hormone melatonin? A:
OPTIONS:
- thymus
- pituitary
- thyroid
- pineal
Answer: pineal
