Task: Question Generation
Input (English): Background Paragraph: The Fink effect, also known as "diffusion anoxia",[1] "diffusion hypoxia",[2] or the "third gas effect",[3] is a factor that influences the pO2 (partial pressure of oxygen) within the alveolus. When water-insoluble gases such as anesthetic agent N2O (nitrous oxide) are breathed in large quantities they can be dissolved in body fluids rapidly. This leads to a temporary increase in both the concentrations and partial pressures of oxygen and carbon dioxide in the alveolus. 
Story: An accident occurred in a local chemical factory. Consequently, large amount of various gases been released to the atmosphere. Local hospital is evaluating all the patients who have been affected by this accident. John, a doctor at the hospital, is seeing two patients, patient A and patient B. He concluded that patient A was having Fink effect. But he didn't see any sign of Fink effect in patient B.
Output (English): Would patient B have breathed large quantities or normal quantities of water-soluble gases?
