Problem: Even as animal domestication became relatively widespread and after the development of agriculture, hunting was usually a significant contributor to the human food supply. The supplementary meat and materials from hunting included protein, bone for implements, sinew for cordage, fur, feathers, rawhide and leather used in clothing. Man's earliest hunting weapons would have included rocks, spears, the atlatl, and bows and arrows. Hunting is still vital in marginal climates, especially those unsuited for pastoral uses or agriculture.[citation needed] For example, Inuit people in the Arctic trap and hunt animals for clothing and use the skins of sea mammals to make kayaks, clothing, and footwear.

Question: In addition to the cathedral, Strasbourg houses several other medieval churches that have survived the many wars and destructions that have plagued the city: the Romanesque Église Saint-Étienne, partly destroyed in 1944 by Allied bombing raids, the part Romanesque, part Gothic, very large Église Saint-Thomas with its Silbermann organ on which Wolfgang Amadeus Mozart and Albert Schweitzer played, the Gothic Église protestante Saint-Pierre-le-Jeune with its crypt dating back to the seventh century and its cloister partly from the eleventh century, the Gothic Église Saint-Guillaume with its fine early-Renaissance stained glass and furniture, the Gothic Église Saint-Jean, the part Gothic, part Art Nouveau Église Sainte-Madeleine, etc. The Neo-Gothic church Saint-Pierre-le-Vieux Catholique (there is also an adjacent church Saint-Pierre-le-Vieux Protestant) serves as a shrine for several 15th-century wood worked and painted altars coming from other, now destroyed churches and installed there for public display. Among the numerous secular medieval buildings, the monumental Ancienne Douane (old custom-house) stands out.

Question: In some countries, the personal copying exemption explicitly requires that the content being copied was obtained legitimately – i.e., from authorized sources, not file-sharing networks. Other countries, such as the Netherlands, make no such distinction; the exemption there had been assumed, even by the government, to apply to any such copying, even from file-sharing networks. However, in April 2014, the Court of Justice of the European Union ruled that "national legislation which makes no distinction between private copies made from lawful sources and those made from counterfeited or pirated sources cannot be tolerated." Thus, in the Netherlands, for example, downloading from file-sharing networks is no longer legal.
Is there an answer to this question: What is an example of a country that the exemption wasn't assumed?

Answer:
unanswerable
