Answer the following question given this paragraph: At a convergent plate boundary, when one plate is oceanic, there are large volcanoes. These volcanoes are found in lines that outline the subduction zone. Earthquakes also happen in these zones. The Aleutian Islands that border southern Alaska are an island arc. In this winter image from space, the volcanoes are covered with snow. Q: At a convergent plate boundary, when one plate is oceanic, there are large what? A:
OPTIONS:
- plateaus
- lakes
- earthquakes
- volcanoes

Answer: volcanoes

Question: Answer the following question given this paragraph: Pure elements with a high metallic character, meaning those that have chemical properties most similar to properties of metals, are generally very reactive. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. Within a compound, metal atoms have a relatively low attraction to shared electrons, as indicated by their low electronegativity values. By following the trend summary in Figure below , you can see that the most reactive metals would reside in the lower left portion of the periodic table. The most reactive metal that occurs naturally in reasonable quantities is cesium, which is always found in nature as a compound, never as a free element. It reacts explosively with water and will ignite spontaneously in air. Francium is below cesium in the alkali metal group, but it is so rare that many of its properties have never even been observed. Q: Exemplified by cesium, which ignites spontaneously in air, pure elements with a high metallic character tend to be very what? A:
OPTIONS:
- radiactive
- inactive
- proactive
- reactive
Answer: reactive

input with options: Answer the following question given this paragraph: Q: Membranes will become increasingly what as temperatures rise? A:
OPTIONS:
- acidic
- metallic
- toxic
- fluid
output: fluid

Q: Answer the following question given this paragraph: The hydrogen bonding that occurs in water leads to some unusual, but very important properties. Most molecular compounds that have a mass similar to water are gases at room temperature. Because of the strong hydrogen bonds, water molecules are able to stay condensed in the liquid state. The Figure below shows how the bent shape and two hydrogen atoms per molecule allows each water molecule to be able to hydrogen bond to two other molecules. Q: Most molecular compounds that have a mass similar to water are in what state of matter at room temperature? A:

OPTIONS:
- solid
- liquid
- vapor
- gas

A: gas

input: OPTIONS:
- pigment
- hydrogen
- diluent
- solvent Now, answer this question: Answer the following question given this paragraph: The presence of solute particles has the opposite effect on the freezing point of a solution. When a solution freezes, only the solvent particles come together to form a solid phase, and the presence of solute particles interferes with that process. Therefore, for the liquid solvent to freeze, more energy must be removed from the solution, which lowers the temperature. Thus, solutions have lower freezing points than pure solvents do. This phenomenon is called freezing point depression. For every mole of particles in a liter of water, the freezing point decreases by about 1.9C. Both boiling point elevation and freezing point depression have practical uses. For example, solutions of water and ethylene glycol (C2H6O2) are used as coolants in automobile engines because the boiling point of such a solution is greater than 100C, the normal boiling point of water. In winter, salts like NaCl and CaCl2 are sprinkled on the ground to melt ice or keep ice from forming on roads and sidewalks. This is because the solution made by dissolving sodium chloride or calcium chloride in water has a lower freezing point than pure water, so the formation of ice is inhibited. Q: When a solution freezes, only what particles come together to form a solid phase, while the presence of solute particles interferes with that process? A:
A:
output: solvent

Question: Answer the following question given this paragraph: Chemical reactions also need energy to be activated. They require a certain amount of energy just to get started. This energy is called activation energy . For example, activation energy is needed to start a car engine. Turning the key causes a spark that activates the burning of gasoline in the engine. The combustion of gas won't occur without the spark of energy to begin the reaction. Q: What do chemical reactions need to be activated? A:
OPTIONS:
- food
- space
- products
- energy
Answer:
energy
