[EX Q]: Passage: In Europe, the North American theater of the Seven Years' War usually is not given a separate name. The entire international conflict is known as the Seven Years' War. 'Seven Years' refers to events in Europe, from the official declaration of war in 1756 to the signing of the peace treaty in 1763. These dates do not correspond with the fighting on mainland North America, where the fighting between the two colonial powers was largely concluded in six years, from the Battle of Jumonville Glen in 1754 to the capture of Montreal in 1760. Question: How long did the fighting last in Seven Years War?
[EX A]: six years

[EX Q]: Passage: There are some common misconceptions about the outer and inner chloroplast membranes. The fact that chloroplasts are surrounded by a double membrane is often cited as evidence that they are the descendants of endosymbiotic cyanobacteria.

Question: What is evidence chloroplasts descended from endosymbiotic cyanobacteria?
[EX A]:
surrounded by a double membrane
