Task: Question Generation
Input (English): Background Paragraph: One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased. 
Story: In a greenhouse, two new plants have just been planted. Flower D has come from a region of little rainfall. Flower E was taken from an area that sees rain nearly every day of the year.
Output (English): Which flower would be better at handling not being watered for a long period of time?
