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.

Input: Consider Input: Fact 1: Plants live just about everywhere on Earth. 
Fact 2: Most plants are producers.

Output: producers live just about everywhere on Earth.


Input: Consider Input: Fact 1: the Himalayas were formed by rock folding. 
Fact 2: Movements in the earth's crust have folded and cracked the older rocks.

Output: the Himalayas were formed from older rock.


Input: Consider Input: Fact 1: Muscle contraction occurs when muscle fibers get shorter. 
Fact 2: With gradual exercise, the muscle fibers grow shorter, needing less oxygen.


Output: with gradual exercise, muscle contraction occurs and muscles need less oxygen.
