Task: Question Generation
Input (English): Background Paragraph: On Earth, the common weather phenomena include wind, cloud, rain, snow, fog and dust storms. Less common events include natural disasters such as tornadoes, hurricanes, typhoons and ice storms. Almost all familiar weather phenomena occur in the troposphere (the lower part of the atmosphere).  Weather does occur in the stratosphere and can affect weather lower down in the troposphere, but the exact mechanisms are poorly understood.Weather occurs primarily due to  air pressure, temperature and moisture differences between one place to another.  These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics. In other words, the farther from the tropics one lies, the lower the sun angle is, which causes those locations to be cooler due the spread of the sunlight over a greater surface.   The strong temperature contrast between polar and tropical air gives rise to the large scale atmospheric circulation cells and the jet stream.  Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow (see baroclinity).  Weather systems in the tropics, such as monsoons or organized thunderstorm systems, are caused by different processes. 
Story: Two continents were separated by a large ocean. Oceania had milder weather and experienced common weather phenomena, while Lemuria experienced natural disasters.
Output (English): Which continent experienced rain phenomena?
