[Q]: - The gravity of the sun pulls its mass inward - There is a lot of pressure on the Sun - The pressure forces atoms of hydrogen to fuse together in nuclear reactions - The energy from the reactions gives off different kinds of light What might be the last step of the process?
****
[A]: The light travels to the Earth.
input: Please answer the following: - Networks of trees start forming - The trees die off - The dead material provides nutrients for more trees - The rising trees provide shelter - And more organisms begin to thrive What might be the last step of the process?
++++++++++
output: The ecosystem known as a forest is made.
Please answer this: - Minerals fill spaces between bits of sediment - The sediments become glued together - The glued together parts become hard like cement - The sediment becomes a big rock - The rocks erode slowly - The rocks come apart - The rocks become smaller rocks - The rocks continue to erode into smaller rocks What might be the last step of the process?

Answer: The process starts again.
Problem: - A person breathes in oxygen - The oxygen passes through the bronchial tubes to the lungs - The oxygen is moved into the bloodstream - Circulates through the body - The cells in the body exchange the oxygen with carbon dioxide - The bloodstream carries the carbon dioxide back to the lungs What might be the last step of the process?

A: The lungs expel the carbon dioxide through the nose and mouth.
Problem: Given the question: - Water gets into cracks in rocks - The water freezes into ice - The cracks expand - Over time the rocks split What might be the last step of the process?
++++++++++++++++++++++++++++++++
The answer is:
The rocks are now in smaller pieces.
Problem: - The human body takes a breath inward - Air is transported to the lungs - Air reaches the alveoli, the smallest air sacs in the lungs - In the alveoli, air passes into the blood within small capillaries - The gaseous oxygen in the air dissolves into the capillary blood - The dissolved oxygen is picked-up by red blood cells - The red blood cells bind the oxygen via a protein called heme - Red blood cells circulate throughout the body and reach the various tissues - Within small capillaries, the heme release the oxygen What might be the last step of the process?

A:
The oxygen can then reach the cells within the tissue
