Task: Question Generation
Input (English): Background Paragraph: Like water in the ocean, air in the atmosphere exerts pressure that increases with depth. Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity. As a result, air pressure decreases quickly at lower altitudes and then more slowly at higher altitudes. This is illustrated in Figure below . Air pressure is greatest at sea level, where the depth of the atmosphere is greatest. At higher altitudes, the pressure is less because the depth of the atmosphere is less. For example, on top of Mount Everest, the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level. At such high altitudes, low air pressure makes it hard to breathe and is dangerous to human health. 
Story: Molly has just moved to a new city for a job she was just hired for. She used to live in a city up in the mountains named Midgar. She liked living there due to the hikes she could go on and seeing the beautiful nature of the hills and mountains. The town she lives in now, Treno, is closer to sea level and is mostly flat plains and farm land. It's a change of scenery, and she hopes she starts to enjoy it more.
Output (English): Which city is less hazardous to Molly's health?
