【正确答案】 A
【答案解析】[听力原文] Central American nations have reached an agreement to allow about 7,000 Cuban migrants stranded in Costa Rica to continue their journey towards the United States. They'll be airlifted to E1 Salvador and put on buses for the US. The current crisis began in November when Nicaragua, a close ally of Cuba, denied access to thousands of migrants arriving from Costa Rica. They have been stuck at the border in precarious conditions for over a month. After a meeting in Guatemala, foreign ministers from Central American nations and Mexico agreed to give them passage. Many Cuban migrants feared that the thawing relations between Washington and Havana may put an end to the preferential treatment given to them. Cubans, who arrived at the US border by land, are allowed to enter the country and apply for residency. What have Central American nations reached? 此题问的是中美洲国家达成的共识。由画线句子可知中美国家就允许7,000名滞留在哥斯达黎加的古巴移民进入美国境内达成一致。故答案为A。
