Task: Question Answering
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: Pam and Jill studied mammals. Jill was fascinated with their nutrition, while Pam was more interested and read about the natural selection phenomenon. 
Question: Which person studied more about organisms with traits that better enable them to adapt to their environment?
Output (English): Pam.
