The White House on Thursday turned down Putin's proposal to hold public talks with Biden.The Russian Foreign Ministry has demanded an explanation from the US for Biden's "killer" remark in an ABC News interview on Wednesday, while Kremlin spokesman Dmitry Peskov called the comment a clear sign that the US president has no intention of repairing relations with Moscow.During a television interview, Putin responded to Biden's strong language by saying that the West is Russophobic. He called the US a "murderous state"－pointing at the US history of slavery, its slaughter of Native Americans and the atomic bombings of Japan in World War II."Be healthy. I wish him good health," said Putin, adding that he really meant what he was saying without a pinch of irony. A: description B: narration C: exposition
