根据以下资料，回答15~18题。 Of all Barry H．Landau"s anecdotes about his friendships with presidential dogs, perhaps the best is the one about the time the Clinton White House called to postpone his play-date with Buddy． Yes, Landau is both human and an adult, a 60-year-old author, presidential historian, former White House protocol officer and memorabilia collector．But so enamored is he of dogs, and so well connected to a succession of presidents, that he had an appointment for a South Lawn romp one day with Buddy, Bill Clinton"s Labrador retriever (拉布拉多犬) . Logistics got in the way, though, and hence Clinton secretary Betty Currie"s apologetic voice mail left at the Smithsonian Institution, where Landau was doing research: "I"m sorry, but we"ll have to reschedule Mr．Landau"s play-date with Buddy." Not surprisingly, this is a happy week for Landau, with the new Obama family dog, Bo, joining a White House tradition that dates to George Washington．It"s one that Landau feels is invaluable to a presidency. "Having a dog just humanizes a president," he says．"It completes the picture．It"s something people can relate to." And Landau has related to the best of them．He"s known about 25 White House dogs since the Eisenhower administration．Among the presidential-pooch memorabilia in his Manhattan apartment are matching orange inaugural dog coats worn by LBJ"s twin beagles (小猎犬) , Him and Her, and a photo of Landau kissing Clipper, JFK"s German shepherd. Who"s "Buddy"？ A．Barry Landau"s friend B．Betty Currie"s cousin C．Bill Clinton"s dog D．George Washington"s play-date.
