Task: Question Generation
Input (English): Background Paragraph: A period of very low rainfall occurred while the Grants were on the islands. The drought resulted in fewer seeds for the finches to eat. Birds with smaller beaks could eat only the smaller seeds. Birds with bigger beaks were better off. They could eat seeds of all sizes. Therefore, there was more food available to them. Many of the small-beaked birds died in the drought. More of the big-beaked birds survived and reproduced. Within just a couple of years, the average beak size in the finches increased. This was clearly evolution by natural selection. 
Story: Two bird islands experienced different levels of rainfall. West island experienced a lengthy drought that lasted several years. Many birds were affected by this drought. East island had several normal years as far as rainfall was concerned.
Output (English): Which island had fewer birds with smaller beaks that were better off?
