Combine the given two facts to write a concluding fact. Note that there should be some parts of the first and second facts that are not mentioned in this conclusion fact. Your combined fact should be the result of a chain between the two facts. Chains form when two facts connect together to produce a concluding fact. An example of a chain is: "pesticides cause pollution" (fact1) + "pollution can harm animals" (fact2) → "pesticides can harm animals" (conclusion fact). Parts of the concluding fact overlap with the first and the second fact. To construct such a  concluding fact, a useful way is to borrow the subject from one fact and the ending conclusions from another fact.

Example Input: Fact 1: Balance is the ability to sense and maintain body position. 
Fact 2: Another name for sense of body position is proprioception.
Example Output: Balance involves proprioception ability.

Example Input: Fact 1: Ethanol is produced by alcoholic fermentation of the glucose in corn or other plants. 
Fact 2: Ethanol is a fuel made of corn.
Example Output: fermentation can be used to make fuel.

Example Input: Fact 1: when a hemisphere is tilted away from the sun , that hemisphere receives less direct sunlight. 
Fact 2: Direct sunlight increases temperature and evaporation rates at the soil and leaf surfaces.
Example Output:
the temperature of the soil of a hemisphere cools down when tilted away from the sun.
