Question mark
In the early 13th century, when the growth of communities of scholars (universities) in Paris and other major cities led to an expansion and streamlining of the book-production trade, punctuation was rationalized by assigning Alcuin's stroke-over-dot specifically to interrogatives; by this time the stroke was more sharply curved and can easily be recognized as the modern question mark.
Doubtful Point
Doubtful Point () is a point forming the east side of the entrance to Enten Bay, Cumberland West Bay, in South Georgia in the southern Atlantic Ocean. The name appears to be first used on a 1929 British Admiralty chart.
