Question: Passage: Later, the constitution was amended to state that the citizens of the 16 states had successfully achieved the unity of Germany in free self-determination and that the Basic Law thus applied to the entire German people. Article 23, which had allowed "any other parts of Germany" to join, was rephrased. It had been used in 1957 to reintegrate the Saar Protectorate as the Saarland into the Federal Republic, and this was used as a model for German reunification in 1990. The amended article now defines the participation of the Federal Council and the 16 German states in matters concerning the European Union.

Answer: What was amended to signify that Basic Law no longer applied to the German people?

Question: Passage: On 7 February 2007, the French Parliament passed a bill granting COM status to both St. Barthelemy and (separately) to the neighbouring Saint Martin. The new status took effect on 15 July 2007, when the first territorial council was elected, according to the law. The island has a president (elected every five years), a unicameral Territorial Council of nineteen members who are elected by popular vote and serve for five-year terms, and an executive council of seven members. Elections to these councils were first held on 1 July 2007 with the last election in March 2012.

Question: Passage: Xiamen dialect, sometimes known as Amoy, is the main dialect spoken in the Chinese city of Xiamen and its surrounding regions of Tong'an and Xiang'an, both of which are now included in the Greater Xiamen area. This dialect developed in the late Ming dynasty when Xiamen was increasingly taking over Quanzhou's position as the main port of trade in southeastern China. Quanzhou traders began travelling southwards to Xiamen to carry on their businesses while Zhangzhou peasants began traveling northwards to Xiamen in search of job opportunities. It is at this time when a need for a common language arose. The Quanzhou and Zhangzhou varieties are similar in many ways (as can be seen from the common place of Henan Luoyang where they originated), but due to differences in accents, communication can be a problem. Quanzhou businessmen considered their speech to be the prestige accent and considered Zhangzhou's to be a village dialect. Over the centuries, dialect leveling occurred and the two speeches mixed to produce the Amoy dialect.

Answer:
During what dynasty did the Xiemen dialect disapear?
