Task: Question Generation
Input (English): Background Paragraph: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe’s neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks. 
Story: Dan studied two islands. Loon island had a very stable environment, and there weren't many diverse species of plants and animals. Wolf island displayed lots of evidence for natural selection, and had a large variety of species inhabiting it.
Output (English): Which island had animals that displayed fewer unfavorable heritable traits?
