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: the gravitational pull of the Moon on Earth 's oceans causes the tides. 
Fact 2: Tides create current.
Example Output: The gravitational pull of the Moon on Earth's ocean contributes to ocean currents.

Example Input: Fact 1: Some mollusks are nearly microscopic. 
Fact 2: Interestingly, a squid is also a mollusk.
Example Output: Some squids are nearly microscopic.

Example Input: Fact 1: Animals use saturated fatty acids to store energy. 
Fact 2: Fatty acids and glucose are the body's primary energy sources.
