Q: Answer the following question given this paragraph: Urine is a liquid that is formed by the kidneys when they filter wastes from the blood. Urine contains mostly water, but it also contains salts and nitrogen-containing molecules. The amount of urine released from the body depends on many things. Some of these include the amount of fluid and food a person consumes and how much fluid they have lost from sweating and breathing. Urine ranges from colorless to dark yellow but is usually a pale yellow color. Light yellow urine contains mostly water. The darker the urine, the less water it contains. Q: Where is urine formed in the body? A:
Answer: the kidneys

Problem:OPTIONS:
- positive
- effective
- caused
- negative

Answer the following question given this paragraph: If the experimental value is less than the accepted value, the error is negative. If the experimental value is larger than the accepted value, the error is positive. Often, error is reported as the absolute value of the difference in order to avoid the confusion of a negative error. The percent error is the absolute value of the error divided by the accepted value and multiplied by 100%. Q: If the experimental value is less than the accepted value, the error is what? A:
****
A: negative

Answer the following question given this paragraph: Q: Through which process does water from the oceans enter the atmosphere? A:
OPTIONS:
- oxidation
- perspiration
- absorption
- evaporation
evaporation

Answer the following question given this paragraph: Some machines change the direction of the force applied by the user. They may or may not also change the strength of the force or the distance over which the force is applied. Two examples of machines that work this way are the claw ends of hammers and flagpole pulleys. You can see in the Figure below how each of these machines works. In both cases, the direction of the force applied by the user is reversed by the machine. Q: Claw ends of hammers and flagpole pulleys are examples of simple machines that reverse what? A:
OPTIONS:
- direction of power
- direction of work
- direction of friction
- direction of force

Answer: direction of force

Question: Answer the following question given this paragraph: What is one of the most important characteristics of a referee? A referee must be neutral. He can't favor one team over the other. In chemistry, being neutral means not being an acid or a base. Pure water is an example of a neutral substance. In some chemical reactions, an acid and a base combine to form neutral products, including water. You'll see how this happens when you read this article. Q: What do you call a substance that is not an acid or a base? A:
OPTIONS:
- equivalent
- toxic
- oxidic
- neutral
Answer: neutral

input: OPTIONS:
- induction
- convection
- thermal radiation
- conduction Now, answer this question: Answer the following question given this paragraph: Sunlight is turned into electricity at a solar power plant. These power plants use a large group of mirrors to focus sunlight on one place. This place is called a receiver ( Figure below ). At the receiver, a liquid such as oil or water is heated to a high temperature. The liquid transfers its heat by conduction . In conduction, energy moves between two objects that are in contact. The higher temperature object transfers heat to the lower temperature object. For example, when you heat a pot of water on a stove top, energy moves from the pot to its metal handle by conduction. At a solar power plant, the energy conducted by the heated liquid is used to make electricity. Q: When you heat a pot of water on a stove top, energy moves from the pot to its metal handle by what process? A:
A:
output:
conduction
