Being one of the four ancient capitals of China, Nanjing has always been a cultural centre attracting intellectuals from all over the country. In the Tang and Song dynasties, Nanjing was a place where poets gathered and composed poems reminiscent of its luxurious past; during the Ming and Qing dynasties, the city was the official imperial examination centre (Jiangnan Examination Hall) for the Jiangnan region, again acting as a hub where different thoughts and opinions converged and thrived.
In what dynasties did poets congregate in Nanjing?
the Tang and Song dynasties

Within the Indo-European language tree, Dutch is grouped within the Germanic languages, which means it shares a common ancestor with languages such as English, German, and Scandinavian languages. All Germanic languages are united by subjection to the sound shifts of Grimm's law and Verner's law which originated in the Proto-Germanic language and define the basic differentiating features from other Indo-European languages. This assumed to have originated in approximately the mid-first millennium BCE in Iron Age northern Europe.
Along with Grimm's law, what's the other rule for Germanic-sounding speech called?
Verner's law

Jeffries and Ryan (2001) argue that the modern concept of separation of church and state dates from the mid-twentieth century rulings of the Supreme Court. The central point, they argue, was a constitutional ban against aid to religious schools, followed by a later ban on religious observance in public education. Jeffries and Ryan argue that these two propositions—that public aid should not go to religious schools and that public schools should not be religious—make up the separationist position of the modern Establishment Clause.
What was the central point of the rulings of the Supreme Court's rulings?
constitutional ban against aid to religious schools
