A-F: "The exhibition marked the end of Nadal's illustrious career, with the Spaniard set to retire following the Davis Cup Finals next month." This pairing makes sense as it logically describes Nadal’s career ending and his upcoming retirement. C-E: "Over the coming decades, global temperatures will continue to rise, but we don’t yet know how much and how fast will they rise." This pairing is accurate as it reflects the uncertainty about the extent of future temperature increases. The other combinations do not form coherent or relevant sentences.
