[Q]: - The water combines with carbon dioxide in the air to form carbonic acid - As the acid is formed, the iron starts to dissolve - Some of the water breaks down into hydrogen and oxygen - The free oxygen and dissolved iron bond together - They form iron oxide, which is rust - What might be the first step of the process?
****
[A]: Water comes into contact with something made of iron

input: Please answer the following: - Liver also cleans blood that has just been enriched with vitamins and minerals during digestion - Liver processes the good stuff into forms that the rest of the body can use - Waste or stuff your body doesn't need can be carried by bile back into the intestine or into the kidneys - The liver also produces a digestive juice called bile that helps the body absorb fat into the bloodstream - The liver also stores extra carbohydrates as glycogen for the body to use as fuel when needed. What might be the first step of the process?
++++++++++

Problem: - The plants and floor absorb the the sunlight - The absorbed sunlight is converted to heat - The heat cannot escape the glass - The heat is trapped in the greenhouse - The hot air rises - The colder air at the top is pushed to the bottom - The colder air is then warmed by the floor and the plants. What might be the first step of the process?

A:
Sunlight passes through the glass into the greenhouse
