The Portuguese language is the official national language and the primary language taught in schools. English and Spanish are also part of the official curriculum. The city has six international schools: American School of Brasilia, Brasilia International School (BIS), Escola das Nacoes, Swiss International School (SIS), Lycee francais Francois-Mitterrand (LfFM) and Maple Bear Canadian School. August 2016 will see the opening of a new international school - The British School of Brasilia. Brasilia has two universities, three university centers, and many private colleges.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When will a new international school open in Brasilia?
Ah, so.. August 2016

Development of the methods used in modern printed circuit boards started early in the 20th century. In 1903, a German inventor, Albert Hanson, described flat foil conductors laminated to an insulating board, in multiple layers. Thomas Edison experimented with chemical methods of plating conductors onto linen paper in 1904. Arthur Berry in 1913 patented a print-and-etch method in Britain, and in the United States Max Schoop obtained a patent to flame-spray metal onto a board through a patterned mask. Charles Ducas in 1927 patented a method of electroplating circuit patterns.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who obtained a patent in 1927 for his method of electroplating circuit patterns?
Ah, so.. Charles Ducas

There is evidence of induced copper deficiency in those taking 100300 mg of zinc daily. A 2007 trial observed that elderly men taking 80 mg daily were hospitalized for urinary complications more often than those taking a placebo. The USDA RDA is 11 and 8 mg Zn/day for men and women, respectively. Levels of 100300 mg may interfere with the utilization of copper and iron or adversely affect cholesterol. Levels of zinc in excess of 500 ppm in soil interfere with the ability of plants to absorb other essential metals, such as iron and manganese. There is also a condition called the zinc shakes or "zinc chills" that can be induced by the inhalation of freshly formed zinc oxide formed during the welding of galvanized materials. Zinc is a common ingredient of denture cream which may contain between 17 and 38 mg of zinc per gram. There have been claims of disability, and even death, due to excessive use of these products.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Having an excess of 500ppm of zinc in soil interferes with what?
Ah, so..
ability of plants to absorb other essential metals
