The one thing shown below that is not true about Gutenberg's printing press of 1450 is option <em>D. In the mid-1400s printing presses began appearing as far as North America.</em>
Primitive forms of printing had been invented in ancient China, but "movable type" printing press was invented by Gutenberg. Before his invention, in Europe, most books were copied by hand. This took a lot of time, and books were owned mostly by the Church or powerful and rich people. After Gutenberg's invention books became cheaper and so more people could read.
The most detailed Roman mosaics use small stones to achieve an effect like brushstrokes. Especially in the eastern provinces of the Roman empire, artists “painted” with stone. Hope this helped :)
