SAT Cross-Text Connections Question

Text 1 Norse settlers occupied part of Greenland from about 985 CE until the early 15th century, when they mysterious abandoned the region. Many researchers cite increasingly lower temperatures to explain why the Norse fled. The researchers reason that the Norse settlers arrived in the region while the climate was warm and were able to remain there until temperatures declined during the Little Ice Age, which occurred between the 14th and 19th centuries. Text 2 Jeffrey Salacup, Isla Castañeda, and colleagues analyzed sediment samples from a lake in Greenland close to the Norse settlement. This allowed them to reconstruct the area's climate history. The researchers found no evidence of substantial temperature changes during the settlement period. They argue that instead the region experienced a persistent drought, which played a more important role in forcing the Norse out of the area than did increasingly lower temperatures. Based on the texts, the researchers in both passages address which question?
