input: Please answer the following: What is the missing first step of the following process: - After a rain, water seeps into cracks and pores of soil and rock - The water percolates beneath the land surface - Some of the water reaches a zone where all the cracks and pores in the rock are already filled with water - Rainwater absorbs some carbon dioxide as it passes through the atmosphere and even more as it drains through soil and decaying vegetation - The water combines chemically with the carbon dioxide - A weak carbonic acid solution is formed - This acid slowly dissolves calcite, forms solution cavities, and excavates passageways -
++++++++++
output: Solution caves are formed in limestone and similar rocks by the action of water

Problem: Given the question: What is the missing first step of the following process: - Diaphragm and other muscles expand to allow room for your lungs to fill - The air flows into the narrow bronchioles in the lungs - From the bronchioles to the alveoli - The oxygen enters into the bloodstream - Is switched with the carbon dioxide in the bloodstream - The carbon dioxide enters through the alveoli - Through the narrow bronchioles - Into the lungs - The carbon dioxide is exhaled out of the body.
++++++++++++++++++++++++++++++++
The answer is:
You breathe in

Problem: What is the missing first step of the following process: - Your town or a private company collect and transport the aluminum to a recycling facility - The aluminum is sorted and cleaned at the central recycling facility - The aluminum is melted down to remove coatings and inks - The melted aluminum is formed into large formations called ingots - The ingots are transported to another facility and rolled out to make them easier to manipulate - The ingots can now be turned into new aluminum products.

A:
You place aluminum cans and other products into recycling bins
