Poniżej znajdziecie wybrane odpowiedzi do quizu. Polecam korzystanie z kombinacji klawiszy CTRL+F do filtrowania pytań. Zbiór odpowiedzi nie jest pełny, a pula pytań może się z czasem poszerzać. Jeżeli nie znajdziecie danego pytania na liście, to spróbujcie sami na nie odpowiedzieć lub po prostu strzelić w najbardziej prawdopodobną opcję. A nuż się uda :) . Do zaliczenia potrzebujecie 12 prawidłowych odpowiedzi, ale test można poprawiać do skutku.
