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.

Input: Consider Input: Fact 1: Babies that are very large or very small at birth are less likely to survive. 
Fact 2: Poor nutrition while in the womb is the major reason why babies are small at birth.

Output: Babies who had poor nutrition while in the womb are less likely to survive.


Input: Consider Input: Fact 1: Phylogeny is the evolutionary history of a group of related organisms. 
Fact 2: Classification can be based on phylogeny.

Output: classification can be based in the evolutionary history of a group of related organisms.


Input: Consider Input: Fact 1: the movement of tectonic plates causes volcanic eruptions. 
Fact 2: The San Andreas is a "transform fault" that marks the boundary between two tectonic plates --  the North American and the Pacific.


Output: The movement of two things that come together in San Andreas causes volcanic eruptions.
