Problem: Victoria's youngest son, Leopold, was affected by the blood-clotting disease haemophilia B and two of her five daughters, Alice and Beatrice, were carriers. Royal haemophiliacs descended from Victoria included her great-grandsons, Tsarevich Alexei of Russia, Alfonso, Prince of Asturias, and Infante Gonzalo of Spain. The presence of the disease in Victoria's descendants, but not in her ancestors, led to modern speculation that her true father was not the Duke of Kent but a haemophiliac. There is no documentary evidence of a haemophiliac in connection with Victoria's mother, and as male carriers always suffer the disease, even if such a man had existed he would have been seriously ill. It is more likely that the mutation arose spontaneously because Victoria's father was over 50 at the time of her conception and haemophilia arises more frequently in the children of older fathers. Spontaneous mutations account for about a third of cases.

Problem: Local associations of a special kind are an amalgamation of one or more Landkreise with one or more Kreisfreie Städte to form a replacement of the aforementioned administrative entities at the district level. They are intended to implement simplification of administration at that level. Typically, a district-free city or town and its urban hinterland are grouped into such an association, or Kommunalverband besonderer Art. Such an organization requires the issuing of special laws by the governing state, since they are not covered by the normal administrative structure of the respective states.
What purpose is district level administration?

Problem: Zhejiang is mountainous and has therefore fostered the development of many distinct local cultures. Linguistically speaking, Zhejiang is extremely diverse. Most inhabitants of Zhejiang speak Wu, but the Wu dialects are very diverse, especially in the south, where one valley may speak a dialect completely unintelligible to the next valley a few kilometers away. Other varieties of Chinese are spoken as well, mostly along the borders; Mandarin and Huizhou dialects are spoken on the border with Anhui, while Min dialects are spoken on the border with Fujian. (See Hangzhou dialect, Shaoxing dialect, Ningbo dialect, Wenzhou dialect, Taizhou dialect, Jinhua dialect, and Quzhou dialect for more information).
