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: soil is formed by rocks eroding. 
Fact 2: Soils are formed by breakdown of rock.
Example Output: rocks eroding causes them to breakdown.

Example Input: Fact 1: a radio converts electrical energy into vibrations. 
Fact 2: Electrical energy refers to energy associated with the flow of electrons.
Example Output: a radio converts the flow of electrons into vibrations.

Example Input: Fact 1: adding salt to a liquid decreases the melting point of that liquid. 
Fact 2: Salinity A word describing the salt content of a liquid.
Example Output:
Higher salinity will decrease the melting point of a liquid.
