Federalism is one of the entrenched constitutional principles of Germany. According to the German constitution (called Grundgesetz or in English Basic Law), some topics, such as foreign affairs and defense, are the exclusive responsibility of the federation (i.e., the federal level), while others fall under the shared authority of the states and the federation; the states retain residual legislative authority for all other areas, including "culture", which in Germany includes not only topics such as financial promotion of arts and sciences, but also most forms of education and job training. Though international relations including international treaties are primarily the responsibility of the federal level, the constituent states have certain limited powers in this area: in matters that affect them directly, the states defend their interests at the federal level through the Bundesrat (literally Federal Council, the upper house of the German Federal Parliament) and in areas where they have legislative authority they have limited powers to conclude international treaties "with the consent of the federal government".
What is a topic that is the exclusive responsibility of the state?
A: unanswerable

The rivalry between Nintendo and Sega resulted in what has been described as one of the most notable console wars in video game history, in which Sega positioned the Genesis as the "cool" console, with more mature titles aimed at older gamers, and edgy advertisements that occasionally attacked the competition. Nintendo however, scored an early public relations advantage by securing the first console conversion of Capcom's arcade classic Street Fighter II for SNES, which took over a year to make the transition to Genesis. Despite the Genesis's head start, much larger library of games, and lower price point, the Genesis only represented an estimated 60% of the American 16-bit console market in June 1992, and neither console could maintain a definitive lead for several years. Donkey Kong Country is said to have helped establish the SNES's market prominence in the latter years of the 16-bit generation, and for a time, maintain against the PlayStation and Saturn. According to Nintendo, the company had sold more than 20 million SNES units in the U.S. According to a 2014 Wedbush Securities report based on NPD sales data, the SNES ultimately outsold the Genesis in the U.S. market.
What game was key to the SNES's success?
A:
Donkey Kong Country
