Q: Answer the following question given this paragraph: Based on their knowledge of subatomic particles, scientists have developed a theory called the standard model to explain all the matter in the universe and how it is held together. The model includes only the fundamental particles in the Table above . No other particles are needed to explain all kinds of matter. According to the model, all known matter consists of quarks and leptons that interact by exchanging bosons, which transmit fundamental forces. The standard model is a good theory because all of its predictions have been verified by experimental data. However, the model doesn't explain everything, including the force of gravity and why matter has mass. Scientists continue to search for evidence that will allow them to explain these aspects of force and matter as well. You can learn much more about the standard model at the URL below. Click on "the standard model" and follow the sequence titled "What is fundamental?". Q: What is the theory scientists use to explain the matter in the universe and how it's held together? A:

OPTIONS:
- specific model
- original model
- organic model
- standard model

A: standard model

input: OPTIONS:
- brain
- liver
- lung
- heart Now, answer this question: Answer the following question given this paragraph: Systemic circulation is the longer loop of the cardiovascular system. It carries blood between the heart and the rest of the body. Oxygen-rich blood flows from the heart to cells throughout the body. As it passes cells, the blood releases oxygen and absorbs carbon dioxide. Then the oxygen-poor blood returns to the heart. Q: In the cardiovascular system, where is the ultimate destination of the oxygen-poor blood? A:
A:
output: heart

Answer the following question given this paragraph: Viscosity () is the resistance of a liquid to flow. Some liquids, such as gasoline, ethanol, and water, flow very readily and hence have a low viscosity. Others, such as motor oil, molasses, and maple syrup, flow very slowly and have a high viscosity. The two most common methods for evaluating the viscosity of a liquid are (1) to measure the time it takes for a quantity of liquid to flow through a narrow vertical tube and (2) to measure the time it takes steel balls to fall through a given volume of the liquid. The higher the viscosity, the slower the liquid flows through the tube and the steel balls fall. Viscosity is expressed in units of the poise (mPas); the higher the number, the higher the viscosity. The viscosities of some representative liquids are listed in Table 11.4 "Surface Tension, Viscosity, Vapor Pressure (at 25C Unless Otherwise Indicated), and Normal Boiling Points of Common Liquids" and show a correlation between viscosity and intermolecular forces. Because a liquid can flow only if the molecules can move past one another with minimal resistance, strong intermolecular attractive forces make it more difficult for molecules to move with respect to one another. The addition of a second hydroxyl group to ethanol, for example, which produces ethylene glycol (HOCH2CH2OH), increases the viscosity 15-fold. This effect is due to the increased number of hydrogen bonds that can form between hydroxyl groups in adjacent molecules, resulting in dramatically stronger intermolecular attractive forces. Q: What is the resistance of a liquid to flow called? A:

OPTIONS:
- turbulence
- permeability
- elasticity
- viscosity

Answer: viscosity

Q: Answer the following question given this paragraph: The magnetic field produced by a current in a wire moves around the wire in concentric circles. More current creates a stronger magnetic field, and the direction of the current determines the direction of the magnetic field. Q: How does the magnetic field produced by a current in a wire move? A:
Answer: in concentric circles

- atoms
- molecular bonds
- electrical charge
- terms of moles

****
A: terms of moles

Problem:OPTIONS:
- calculators
- patterns
- microscopes

Answer the following question given this paragraph: Scientists create models with computers. Computers can handle enormous amounts of data. This can more accurately represent the real situation. For example, Earth's climate depends on an enormous number of factors. Climate models can predict how climate will change as certain gases are added to the atmosphere. To test how good a model is, scientists might start a test run at a time in the past. If the model can predict the present it is probably a good model. It is more likely to be accurate when predicting the future. Q: What technology do scientists use to create models? A:
****
A:
computers
