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: Algae have varied life cycles. 
Fact 2: Coccolithophorids are members of the Algae.
Example Output: Coccolithophorids have varied life cycles.

Example Input: Fact 1: Chemical bonds form when substances react with one another. 
Fact 2: All substances are composed of molecules.
Example Output: Chemical bonds form when molecules react with one another.

Example Input: Fact 1: dropping an object into water causes vibrations in the water. 
Fact 2: Water, for example, is a liquid.
Example Output:
dropping an object into liquid causes vibrations in the liquid.
