input: OPTIONS:
- hormones
- stomach acid
- urine
- water Now, answer this question: Answer the following question given this paragraph: The skin has multiple roles in the body. Many of these roles are related to homeostasis. The skin's main functions are preventing water loss from the body and serving as a barrier to the entry of microorganisms. In addition, melanin in the skin blocks UV light and protects deeper layers from its damaging effects. Q: The skin plays an important role in preventing the escape of what commonly found liquid from the body? A:
A:
output: water

Answer the following question given this paragraph: Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control. But in the case of cancer, these systems fail. Cancer is usually caused by mutations. Mutations are random errors in genes. Mutations that lead to cancer usually happen to genes that control the cell cycle. Because of the mutations, abnormal cells divide uncontrollably. This often leads to the development of a tumor. A tumor is a mass of abnormal tissue. As a tumor grows, it may harm normal tissues around it. Anything that can cause cancer is called a carcinogen . Carcinogens may be pathogens, chemicals, or radiation. Q: Which disease causes cells to divide out of control A:

OPTIONS:
- autoimmune diseases
- mutation
- arthritis
- cancer

Answer: cancer

Problem: OPTIONS:
- big explosion
- good bang
- big bust
- big bang
Q: Answer the following question given this paragraph: About 13.7 billion years ago, the entire universe was packed together. Everything was squeezed into a tiny volume. Then there was an enormous explosion. After this "big bang," the universe expanded rapidly ( Figure below ). All of the matter and energy in the universe has been expanding ever since. Scientists have evidence this is how the universe formed. One piece of evidence is that we see galaxies moving away from us. If they are moving apart, they must once have been together. Also, there is energy left over from this explosion throughout the universe. The theory for the origin of the universe is called the Big Bang Theory . Q: The once compressed universe expanded rapidly after what nicknamed event billions of years ago? A:
Answer: big bang

Answer the following question given this paragraph: One common application of inductance is used in traffic lights that can tell when vehicles are waiting at the intersection. An electrical circuit with an inductor is placed in the road under the place a waiting car will stop over. The body of the car increases the inductance and the circuit changes sending a signal to the traffic lights to change colors. Similarly, metal detectors used for airport security employ the same technique. A coil or inductor in the metal detector frame acts as both a transmitter and a receiver. The pulsed signal in the transmitter coil induces a signal in the receiver. The self-inductance of the circuit is affected by any metal object in the path. Such detectors can be adjusted for sensitivity and also can indicate the approximate location of metal found on a person. (But they will not be able to detect any plastic explosive such as that found on the "underwear bomber. ") See Figure 23.43. Q: Metal detectors used for airport security work on which principle? A:
OPTIONS:
- electricity
- inertia
- conductivity
- inductance

Answer:
inductance
