Well, one starts with "On December 22, 2008, Ansol Clark woke to a ringing phone. It was sometime before 6 a.m., far earlier than he had intended to get up. He drove construction trucks for a living, but he’d been furloughed recently, leaving him little to do in the three days before Christmas except wrap gifts and watch movies with his grown son, Bergan." while the other starts with "The Kingston Fossil Plant Spill was an environmental and industrial disaster that occurred on December 22, 2008, when a dike ruptured at a coal ash pond at the Tennessee Valley Authority (TVA)'s Kingston Fossil Plant in Roane County, Tennessee, releasing 1.1 billion US gallons (4.2 million cubic metres) of coal fly ash slurry."
