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: Secondary growth forms secondary vascular tissues and bark. 
Fact 2: Trees have the ability to undergo secondary growth and produce a woody body.
Example Output: trees form secondary vascular tissues and bark.

Example Input: Fact 1: Many nerve pathways link the cerebellum with motor neurons throughout the body. 
Fact 2: And the human body is no exception.
Example Output: In a human, the nerve pathways link the cerebellum with motor neurons.

Example Input: Fact 1: if a planet becomes too hot then that planet cannot sustain life. 
Fact 2: Extremes in temperature can kill animals.
Example Output:
temperatures on a planet that are too hot can not sustain animals.
