Each part consists of several sections. Questions in Part 1 are grouped by their fields, and questions in Part 2 are grouped by languages. You may find almost the same questions in different sections, but this is for the convenience of readers.
We believe that the contents are fairly correct, but please let us know if you find any mistakes. New information is always welcome.
Many people gave us advice in making this list. We would like to thank those who have contributed.
