Task: Question Answering
Input (English): Passage: In October 2002, bilateral and multilateral lenders led by the World Bank agreed to give Yemen a four-year economic support package worth US$2.3 billion, 20 percent in grants and 80 percent in concessional loans. This funding is almost eight times the amount of financial support Yemen received under the IMFs PRGF. However, in December 2005 the World Bank announced that because of the governments continued inability to effect significant economic reforms and stem corruption, funding would be reduced by more than one-third, from US$420 million to US$240 million for the period July 2005 – July 2008. In May 2006, the World Bank adopted a new Country Assistance Strategy (CAS) for Yemen for the period FY 2006 to FY 2009, providing a blueprint for fostering the countrys fiscal and human development improvement. The bank pledged to contribute approximately US$400 million in International Development Association (IDA) credits over the CAS time frame. At present, Yemen owes approximately US$264 million to Japan, one of its largest donors. In December 2005, the Government of Japan pledged to write off US$17 million of the debt. That same month, Germany pledged to increase its annual aid to Yemen to US$83.6 million over the next two years; funding will go primarily to education and water improvement projects. In November 2006, the United Kingdom announced that aid to Yemen would increase 400 percent, to US$222 million through 2011.
