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: dew is formed when water vapor condenses over night. 
Fact 2: Dew begins to evaporate when the temperature reaches the dew point.

Ex Output:
condensed water vapor evaporates at certain temperatures.


Ex Input:
Fact 1: a warm front causes cloudy and rainy weather. 
Fact 2: Behind the warm front are thick, low stratus clouds and possibly more rain.

Ex Output:
cloudy and rainy weather is accompanied by stratus clouds.


Ex Input:
Fact 1: if weather is stormy then there is a greater chance of rain. 
Fact 2: Rain is our usual form of precipitation.

Ex Output:
