Article: Once inside the Rotunda for the Charters of Freedom, there are no lines to see the individual documents and visitors are allowed to walk from document to document as they wish. For over 30 years the National Archives have forbidden flash photography but the advent of cameras with automatic flashes have made the rules increasingly difficult to enforce. As a result, all filming, photographing, and videotaping by the public in the exhibition areas has been prohibited since February 25, 2010.

Question: For how long has the National Archives prohibited flash photography?
Ans: over 30 years


Article: On 16 March 1938, Barcelona came under aerial bombardment from the Italian Air Force, causing more than 3,000 deaths, with one of the bombs hitting the club's offices. A few months later, Catalonia came under occupation and as a symbol of the "undisciplined" Catalanism, the club, now down to just 3,486 members, faced a number of restrictions. All signs of regional nationalism, including language, flag and other signs of separatism were banned throughout Spain. The Catalan flag was banned and the club were prohibited from using non-Spanish names. These measures forced the club to change its name to Club de Fútbol Barcelona and to remove the Catalan flag from its crest.

Question: When did the Italians bomb Barcelona?
Ans: 16 March 1938


Article: The printed circuit board industry defines heavy copper as layers exceeding three ounces of copper, or approximately 0.0042 inches (4.2 mils, 105 μm) thick. PCB designers and fabricators often use heavy copper when design and manufacturing circuit boards in order to increase current-carrying capacity as well as resistance to thermal strains. Heavy copper plated vias transfer heat to external heat sinks. IPC 2152 is a standard for determining current-carrying capacity of printed circuit board traces.

Question: What would a PCB designer use heavy copper to make their circuit board resist?
Ans: thermal strains
