B"Are you crazy?" people around him shouted as Alex Bien, a 33-year-old immigrant （移民）, ran toward three cars in a chain accident along the highway in Miami, which were burning down. Alex didn't think twice.The article "Against the Flames" reported how he put out the fire on a car and pulled a couple out of another. But when he returned to his own car, steam was coming out of it. It was damaged beyond repair.Back in his tiny flat, alone and with little money, Alex didn't know what to do. He was already working, going to college and supporting his wife, Aline, and children back in Haiti. He worried about his wife's health; doctors thought she had cancer（癌症）. Every cent was important to him. And now this.Within weeks of reading the article, readers sent hundreds of letters offering jobs, money and best wishes. One delivered a car — used, but in fine condition. Others helped Aline come to Miami, where a medical team found out it was not cancer.Readers also wrote to U. S. government officials to support the immigration of Alex's family to Miami. Cousul General Roger Daley even invited Alex to discuss the matter. Aline, together with their children, joined Alex in Miami this past March. Alex says, "I would like to say a beautiful thanks to the readers. There are good people everywhere in this world."What did Roger Daley invite Alex to discuss?
A.Alex's new job as a news reporter. B.The medical treatment of Alex's wife. C.Alex's further studies at a U.S. university. D.The immigration of Alex's family to the U.S.正确答案D
