听力原文： Sudanese opposition leader Sadeqal-Mahdi, who travels to Washington next week, says he will push the Bush administration to urge both sides in his country's civil war to make peace and create a true democracy. In an interview with Reuters news agency, Mr. Mahdi says the United States can play an important role in pressuring both sides to reach a just peace through political talks, not war-fare.

Last week, Secretary of State Colin Powell visited the region and promised to try harder to end the Sudanese war, which has killed an estimated two million people. It pits the Muslim north against the largely Christian and animist south.

Sudan's President Omar Hassan Al-Bashir and rebel leader John Garang are to hold proximity talks Saturday in Nairobi along with east African leaders trying to mediate an end to the 18 year conflict. In addition to the Kenyan host, President Daniel-arap Moi, the Ugandan, Ethiopian and Eritrean leaders are to attend the session.

Who has visited Sudan last week？

A．Sadeqal-Mahdi.

B．Colin Powell.

C．Omar Hassan AL-Bashir.

D．President Bush.
