On Saturday, July 23, 1989, much of America learned of the AFL for an unintended reason, when the Pittsburgh Gladiators' head coach, Joe Haering, made football history by punching commissioner Jim Foster during a game with the Chicago Bruisers. The national media ran with the story, including a photo in USA Today. The game was played between the two teams in Sacramento's Arco Arena, as part of the AFL's 'Barnstorming America' tour. Foster had walked onto the field of play to mediate an altercation between the two teams when Haering, a former NFL assistant, punched him in the jaw. Haering was suspended without pay.

By 1860, Houston had emerged as a commercial and railroad hub for the export of cotton. Railroad spurs from the Texas inland converged in Houston, where they met rail lines to the ports of Galveston and Beaumont. During the American Civil War, Houston served as a headquarters for General John Bankhead Magruder, who used the city as an organization point for the Battle of Galveston. After the Civil War, Houston businessmen initiated efforts to widen the city's extensive system of bayous so the city could accept more commerce between downtown and the nearby port of Galveston. By 1890, Houston was the railroad center of Texas.
For what battle was Houston used as an organization point ?
****
The answer: Battle of Galveston

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.
Aside from die casting, what are alloys of zinc mixed with copper, aluminium and magnesium used for?
****
The answer: spin casting

Following the start of the Arab Spring in 2011, Gaddafi spoke out in favour of Tunisian President Zine El Abidine Ben Ali, then threatened by the Tunisian Revolution. He suggested that Tunisia's people would be satisfied if Ben Ali introduced a Jamahiriyah system there. Fearing domestic protest, Libya's government implemented preventative measures, reducing food prices, purging the army leadership of potential defectors and releasing several Islamist prisoners. They proved ineffective, and on 17 February 2011, major protests broke out against Gaddafi's government. Unlike Tunisia or Egypt, Libya was largely religiously homogenous and had no strong Islamist movement, but there was widespread dissatisfaction with the corruption and entrenched systems of patronage, while unemployment had reached around 30%.
About what percentage of the Libyan population was unemployed in 2011?
****
The answer:
30
