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: looking at bright objects has a negative impact on the eyes. 
Fact 2: Most of the bright objects are stars.
Example Output: looking at stars negatively impacts the eyes.

Example Input: Fact 1: recycling reduces the resources needed to make something. 
Fact 2: Recyclability and recycling of materials is essential.
Example Output: It is essential to reduce resources needed to make things.

Example Input: Fact 1: an incandescent light bulb converts electricity into light by sending electricity through a filament. 
Fact 2: Filaments are made of materials that resist the flow of current.
Example Output:
an incandescent light bulb converts electricity into light by sending electricity through a material that resists the flow of current.
