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.

Ex Input:
Fact 1: Plants that are adapted to very dry environments are called xerophytes. 
Fact 2: Bromeliads and cacti are xerophytes.

Ex Output:
Bromeliads and cacti have adapted to very dry environments.


Ex Input:
Fact 1: Protozoa can be classified on the basis of how they move. 
Fact 2: Cryptosporidium parvum is the hardest protozoa to kill.

Ex Output:
Animals like cyptosporidium are often classified on how they move.


Ex Input:
Fact 1: Fission takes place when an animal divides into two parts. 
Fact 2: Flagellates reproduce by binary fission.

Ex Output:

Flagellates reproduce by dividing into two parts.
