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.
The Race Question
The Race Question is the first of four UNESCO statements about issues of race. It was issued on 18 July 1950 following World War II and Nazi racism to clarify what was scientifically known about race, and as a moral condemnation of racism. It was criticized on several grounds and revised versions were publicized in 1951, 1967, and 1978.
