Question: Passage: Although Satsunan literally means the south of Satsuma Province, the north-eastern group of the Ōsumi Islands formed Tane Province for a brief period in the 8th and 9th centuries and then were merged into Ōsumi Province. The Tokara Islands and the northwestern group of the Ōsumi Islands belonged to Kawanabe District of Satsuma Province. The Amami Islands paid tribute to the Ryukyu Kingdom to the South until they were put under direct control in the late 16th century, but were conquered in 1609 by the Satsuma Domain. In 1879, the Amami Islands became Ōshima District of Kagoshima Prefecture. The Tokara Islands and the north-western group of the Ōsumi Islands were transferred to Ōshima District in 1897, and then to Kagoshima District in 1973. After World War II, the Tokara and Amami Islands were put under United States military occupation, which formed the Government of the Northern Ryukyus. The Japanese government fiercely contested the Amami Islands being affiliated with the word "Ryukyu", believing that it would lead to a later return of the islands to their control. The Tokara Islands were returned to Japan in 1952, which were followed by the Amami Islands in December 1953.
Question: Which island was returned to Japan last?

Question: Passage: The Beja Congress was formed in 1952 with the aim of pursuing regional autonomy against the government in Khartoum. Frustrated by the lack of progress, the Beja Congress joined the insurgent National Democratic Alliance in the 1990s. The Beja Congress effectively controlled a part of eastern Sudan centered on Garoura and Hamshkoraib. The Beja Congress sabotaged the oil pipeline to Port Sudan several times during 1999 and 2000. In 2003, they rejected the peace deal arranged between the Sudanese government and the Sudan People's Liberation Army, and allied with the rebel movement of the Darfur region, the Sudan Liberation Movement/Army, in January 2004. A peace agreement was signed with the government of Sudan in October 2006. In the general elections in April 2010, the Beja Congress did not win a single seat in the National Assembly in Khartoum. In anger over alleged election fraud and the slow implementation of the peace agreement, the Beja Congress in October 2011 withdrew from the agreement, and later announced an alliance with the Sudan Liberation Movement/Army.
