input with options: Answer the following question given this paragraph: Snow falls when water vapor condenses as ice crystals. The air temperature is below freezing all the way to the ground, so the ice crystals remain frozen. They fall as flakes. Sleet forms when snow melts as it falls through a layer of warm air and then refreezes. It turns into small, clear ice pellets as it passes through a cold layer near the ground. Freezing rain falls as liquid water. It freezes on contact with cold surfaces near the ground. It may cover everything with a glaze of ice. If the ice is thick, its weight may break tree branches and pull down power lines. Hail is another type of frozen precipitation. Hail forms in thunderstorms when strong updrafts carry rain high into the troposphere. The rain freezes into balls of ice called hailstones. This may happen over and over again until the hailstones are as big as baseballs. Hail forms only in cumulonimbus clouds. Q: What are two types of frozen percipitation? A:
OPTIONS:
- icycles and icebergs
- rain and hail
- ice and frost
- snow and hail
output: snow and hail

input with options: Answer the following question given this paragraph: Small molecules can pass through the plasma membrane through a process called diffusion. Diffusion is the movement of molecules from an area where there is a higher concentration (larger amount) of the substance to an area where there is a lower concentration (lower amount) of the substance ( Figure below ). The amount of a substance in relation to the total volume is the concentration . During diffusion, molecules are said to flow down their concentration gradient , flowing from an area of high concentration to an area of low concentration. Molecules flowing down a concentration gradient is a natural process and does not require energy. Q: What is the process of small molecules passing through the plasma membrane called? A:
OPTIONS:
- permeation
- absorption
- convection
- diffusion
output: diffusion

input with options: Answer the following question given this paragraph: Carbon dioxide chemically weathers rock by creating acids. Q: How does carbon dioxide chemically weather rocks? A:
OPTIONS:
- by creating proteins
- by creating water
- by creating heat
- by creating acids
output: by creating acids

input with options: Answer the following question given this paragraph: Mollusks reproduce sexually. Most species have separate male and female sexes. Fertilization may be internal or external, depending on the species. Fertilized eggs develop into larvae. There may be one or more larval stages. Each one is different from the adult stage. Q: Fertilized mollusk eggs develop into what? A:
OPTIONS:
- shrimp
- bark
- leaf
- larvae
output:
larvae
