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.
Point Danger (Tweed Heads)
In 1970, on the 200th anniversary of Cook's naming of Point Danger and given that the location seemed to be correct, a memorial was placed at the current site and the New South Wales, Queensland and Federal governments combined to erect the Point Danger Captain Cook Memorial Lighthouse. However, in 1971, the following year, after much debate about the location of Cook's Point Danger and the Queensland-New South Wales border, the Geographical Names Board declared:
"little doubt exists that the feature named Point Danger by Captain Cook was in actual fact the feature now known as Fingal Head. However, as the name has been known in its present position for over 130 years and having in mind the wording of the letters Patent of 6 June 1859, in which the position of the QLD-New South Wales border is linked with the position of Point Danger, the Board is not prepared to assign the name to any feature or position other than that to which it is currently located." 
The misnaming obviously raised a significant constitutional issue. Yet despite this pronouncement, some 18 years later debate was still continuing. In November 1989 the Geographical Names Board approved a historical re-enactment of Cook's voyage. The research for the re-enactment led to Acting Chief Surveyor Ron Benjamin finding that:
"From the re-enactment voyage, I now have no doubt that Captain Cook's, 'point of land under which lies a small island', was intended to be today's Fingal Head."
However, in 1998, following another review, the New South Wales Geographic Names Board, it was concluded, in part:
"From an analysis of Cook’s Private Log, the Official Log of the ‘Endeavour’, Cook’s Journal and the journals of Cook’s Officers, and relating the analysis to modern nautical charts and maps of the area, it is suggested that the following conclusions be drawn:
