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: Biodiversity generally increases from the poles to the equator. 
Fact 2: Soil Biodiversity Soil biodiversity reflects the mix of living organisms in the soil.
Example Output: the mix of living organisms generally increases from the poles to the equator.

Example Input: Fact 1: Fungi have special structures for penetrating a host. 
Fact 2: Host tissue penetration occurs to the point of vascular connectivity.
Example Output: Fungi can invade a host to the point of vascular conncectivity.

Example Input: Fact 1: water vapor cooling causes that water vapor to condense. 
Fact 2: Water is made up of H2O molecules.
Example Output:
h2o vapor cooling causes that h2o vapor to condense.
