Given a scientific passage and an answer, generate a question for the given answer.

Example Input: Passage: Gases are also capable of dissolving in liquids. There are many examples of this in our everyday lives. For example, carbonated beverages contain dissolved carbon dioxide. We notice this when bubbles come out of solution when the beverage is opened. Another example is when oxygen from the air we breathe dissolves in our blood, where it is transported throughout the body. Fish and other aquatic organisms use gills to capture dissolved oxygen from their environments. Answer: oxygen
Example Output: Fish and other aquatic organisms use gills to capture dissolved what?

Example Input: Passage: An ionic bond is the force of attraction that holds together oppositely charged ions. Ionic bonds form crystals instead of molecules. Table salt contains ionic bonds. Answer: ionic bond
Example Output: What term means the force of attraction that holds together oppositely charged ions?

Example Input: Passage: One thing is true of both regular and diffuse reflection. The angle at which the reflected rays leave the surface is equal to the angle at which the incident rays strike the surface. This is known as the law of reflection . The law is illustrated in the Figure below and also in this animation: http://www. physicsclassroom. com/mmedia/optics/lr. cfm. Answer: reflection
Example Output:
Which law describes the angle at which the reflected rays leave the surface is equal to the angle at which the incident rays strike the surface?
