input with options: Answer the following question given this paragraph: Ocean water is salty because water dissolves minerals out of rocks. The ions enter the water. This happens whenever water flows over or through rocks. Much of this water and its minerals end up in the oceans. Minerals dissolved in water form salts. When the water evaporates, it leaves the salts behind. As a result, ocean water is much saltier than other water on Earth. Q: Ocean water has what property because water dissolves minerals out of rocks? A:
OPTIONS:
- fizzy
- sweet
- muddy
- salty
output: salty

A:
output: gills

Answer the following question given this paragraph: Steam actually consists of tiny droplets of liquid water. What you can't see in the picture is the water vapor that is also present in the air above the spring. Water vapor is water in the gaseous state. It constantly rises up from the surface of boiling hot water. Why? At high temperatures, particles of a liquid gain enough energy to completely overcome the force of attraction between them, so they change to a gas. The gas forms bubbles that rise to the surface of the liquid because gas is less dense than liquid. The bubbling up of the liquid is called boiling. When the bubbles reach the surface, the gas escapes into the air. The entire process in which a liquid boils and changes to a gas that escapes into the air is called vaporization .
