Question: Passage: Min Nan texts, all Hokkien, can be dated back to the 16th century. One example is the Doctrina Christiana en letra y lengua china, presumably written after 1587 by the Spanish Dominicans in the Philippines. Another is a Ming Dynasty script of a play called Romance of the Lychee Mirror (1566), supposedly the earliest Southern Min colloquial text. Xiamen University has also developed an alphabet based on Pinyin, which has been published in a dictionary called the Minnan Fangyan-Putonghua Cidian () and a language teaching book, which is used to teach the language to foreigners and Chinese non-speakers. It is known as Pumindian.

Answer: Who has developed an alphabet based on Pumindian?

Question: Passage: Consequently, Molotov, fearing that EDC would be directed in the future against the USSR therefore "seeking to prevent the formation of groups of European States directed against other European States", made a proposal for a General European Treaty on Collective Security in Europe "open to all European States without regard as to their social systems" which would have included the unified Germany (thus making the EDC perceived by the USSR as a threat unusable). But Eden, Dulles and Bidault opposed the proposal.

Answer:
