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: A biologist was in Australia making observations about the local species when he identified two distinct groups of butterflies. He found that one group of butterflies, group A, blended in with the dark oak trees that were common in the area. Butterflies in the other group, group B, however did not blend in as well and could easily be spotted by predators whenever they landed on the oak trees.
Question: Will the traits belonging to the group A butterflies become more common or less common over time?

Ex Output:
more common.

Background Paragraph: The first evidence of baking occurred when humans took wild grass grains, soaked them in water, and mixed everything together, mashing it into a kind of slippery and wet broth-like paste.[3] The paste was cooked by pouring it onto a flat, hot rock, resulting in a bread-like substance. Later, when humans mastered fire, the paste was roasted on hot embers, which made bread-making easier, as it could now be made any time fire was created. The world's oldest oven was discovered in Croatia in 2014 dating back 6500 years ago. The Ancient Egyptians baked bread using yeast, which they had previously been using to brew beer.[4] Bread baking began in Ancient Greece around 600 BC, leading to the invention of enclosed ovens.[4] "Ovens and worktables have been discovered in archaeological digs from Turkey (Hacilar) to Palestine (Jericho) and date back to 5600 BC."[5].
Story: Students learned about bread making in school, and were fascinated by the history of bread. They learned ancient bread making techniques that they experimented with later on.Group A experimented with Egyptian and Greek techniques, while group B made it the Croatian and the Turkish way.
Question: Which people had a longer bread baking history, Turkish or Greek?

Ex Output:
Turkish.
