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: Cuticle helps prevent water loss, abrasions, infections, and damage from toxins. 
Fact 2: Transpiration , on the other hand, is the loss of water by plants.
Example Output: cuticle helps prevent transpiration.

Example Input: Fact 1: volcanic ash in the atmosphere decreases the temperature by blocking the sun. 
Fact 2: Most volcanic ash consists of fine, dusty particles.
Example Output: Fine, dusty particles erupted from volcanos decrease the temperature by blocking the sun.

Example Input: Fact 1: if the amount of available food and water decreases in an environment then animals may leave that environment to find food and water. 
Fact 2: Many areas are mostly affected by the persistent drought in the shortage of food and water.
Example Output:
Persistent drought and food shortages can cause animals to leave that environment.
