Answer the following question given this paragraph: There are several different equations that better approximate gas behavior than does the ideal gas law. The first, and simplest, of these was developed by the Dutch scientist Johannes van der Waals in 1879. The van der Waals equation improves upon the ideal gas law by adding two terms: one to account for the volume of the gas molecules and another for the attractive forces between them. Q: Which equation improves upon the ideal gas law by adding two terms: one to account for the volume of the gas molecules and another for the attractive forces between them? A:
****
A: van der waals

Answer the following question given this paragraph: Some metals, such as gold and platinum, do not corrode easily because they are very resistant to oxidation by common substances. Some other metals begin to be oxidized, but are further protected from additional corrosion by a coating formed on the surface. Aluminum reacts with oxygen to form aluminum oxide, which remains tightly packed on the surface. The aluminum oxide prevents the interior of the aluminum from corroding. Not all corrosion is a result of reaction with oxygen. Copper corrodes by reaction with carbon dioxide to form copper(II) carbonate. This distinctive green compound is also called patina and prevents the copper underneath from further corrosion (see Statue of Liberty in the Figure below ). Q: Some metals, such as gold and platinum, do not corrode easily because they are very resistant to what? A:
OPTIONS:
- evaporation
- precipitation
- heat
- oxidation
oxidation

Answer the following question given this paragraph: From the pharynx, the food moves into the esophagus. The esophagus is a long, narrow tube that passes food from the pharynx to the stomach by peristalsis. The esophagus has no other digestive functions. At the end of the esophagus, a muscle called a sphincter controls the entrance to the stomach. The sphincter opens to let food into the stomach and then closes again to prevent food from passing back into the esophagus. Q: What is the name of the muscle at the end of the esophagus? A:
OPTIONS:
- neck
- intestine
- throat
- sphincter

Answer: sphincter

Question: Answer the following question given this paragraph: Earth gets its energy from the Sun. The Sun gives off photons of energy that travel in waves. All the wavelengths of the Sun's energy make up the electromagnetic (EM) spectrum. Q: Where does the earth gets its energy from? A:
OPTIONS:
- decomposers
- precipitation
- heat
- sun
Answer: sun

input with options: Answer the following question given this paragraph: Air enters the respiratory system through the nose. As the air passes through the nasal cavity, mucus and hairs trap any particles in the air. The air is also warmed and moistened so it won't harm delicate tissues of the lungs. Q: In the nasal cavity, what 2 things trap particles from incoming air? A:
OPTIONS:
- phlegm and hair
- saliva and hair
- mucus and skin
- mucus and hair
output: mucus and hair

Problem: OPTIONS:
- one direction
- few directions
- some directions
- all directions
