Problem: Zinc:

Alloys of primarily zinc with small amounts of copper, aluminium, and magnesium are useful in die casting as well as spin casting, especially in the automotive, electrical, and hardware industries. These alloys are marketed under the name Zamak. An example of this is zinc aluminium. The low melting point together with the low viscosity of the alloy makes the production of small and intricate shapes possible. The low working temperature leads to rapid cooling of the cast products and therefore fast assembly is possible. Another alloy, marketed under the brand name Prestal, contains 78% zinc and 22% aluminium and is reported to be nearly as strong as steel but as malleable as plastic. This superplasticity of the alloy allows it to be molded using die casts made of ceramics and cement.

What brand name of alloy is supposed to be as strong as steel while still being malleable as plastic?

A: Prestal


Problem: Communications in Somalia:

Broadband wireless services were offered by both dial up and non-dial up ISPs in major cities, such as Mogadishu, Bosaso, Hargeisa, Galkayo and Kismayo. Pricing ranged from $150 to $300 a month for unlimited internet access, with bandwidth rates of 64 kbit/s up and down. The main patrons of these wireless services were scholastic institutions, corporations, and UN, NGO and diplomatic missions. Mogadishu had the biggest subscriber base nationwide and was also the headquarters of the largest wireless internet services, among which were Dalkom (Wanaag HK), Orbit, Unitel and Webtel.

What was the price for limited internet access?

A: unanswerable


Problem: Florida:

From 1952 to 1964, most voters were registered Democrats, but the state voted for the Republican presidential candidate in every election except for 1964. The following year, Congress passed and President Lyndon B. Johnson signed the Voting Rights Act of 1965, providing for oversight of state practices and enforcement of constitutional voting rights for African Americans and other minorities in order to prevent the discrimination and disenfranchisement that had excluded most of them for decades from the political process.

A: President Lyndon B. Johnson signed the Voting Rights Act of 1965


Problem: Tuvalu:

Captain John Byron passed through the islands of Tuvalu in 1764 during his circumnavigation of the globe as captain of the Dolphin (1751). Byron charted the atolls as Lagoon Islands. Keith S. Chambers and Doug Munro (1980) identified Niutao as the island that Francisco Mourelle de la Rúa sailed past on 5 May 1781, thus solving what Europeans had called The Mystery of Gran Cocal. Mourelle's map and journal named the island El Gran Cocal ('The Great Coconut Plantation'); however, the latitude and longitude was uncertain. Longitude could only be reckoned crudely as accurate chronometers were unavailable until the late 18th century.

When were chronometers available for accurate location charting?

A:
late 18th
