I. Read the passage, and then decide whether the statements are true (T) or false (F).

UNESCO has recognized the 82 Doctors’ stone tablets as
a Memory of the World. They are inscribed with the names of
2,313 doctorate holders who passed the royal examinations
between 1442 and 1780. The stone tablets, which bear the names
of Trang Nguyen, Bang Nhan, Tham Hoa, and Hoang Giap (the
first, second, third and fourth winning categories at the royal
examinations), sit on the backs of stone turtles.
These stone tablets are different from those in other
Asian countries, including China which had influenced

Vietnamese feudal education. The decorations on Viet Nam’s stone tablets were more diverse.
By naming Viet Nam’s stone tablets as a Memory of the World, UNESCO also acknowledges Viet Nam’s
efforts to preserve and promote heritage to international community. The recognition would also help to raise
the awareness in heritage preservation.
