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: if a plant requires less water then that plant will survive in a drought. 
Fact 2: Cacti and succulents can go without water for a long period.
Example Output: cacti are likely to survive in a drought.

Example Input: Fact 1: Most invertebrates have a more complex nervous system. 
Fact 2: Cephalopods have the most advanced nervous systems of all invertebrates.
Example Output: Cephalopods have a complex nervous system.

Example Input: Fact 1: clouds are formed by water vapor rising into colder regions of the atmosphere and condensing. 
Fact 2: Condensation releases energy into atmosphere.
Example Output:
Clouds are formed when water vapor releases energy into the atmosphere.
