question:
Passage: Other widely used alloys that contain zinc include nickel silver, typewriter metal, soft and aluminium solder, and commercial bronze. Zinc is also used in contemporary pipe organs as a substitute for the traditional lead/tin alloy in pipes. Alloys of 85–88% zinc, 4–10% copper, and 2–8% aluminium find limited use in certain types of machine bearings. Zinc is the primary metal used in making American one cent coins since 1982. The zinc core is coated with a thin layer of copper to give the impression of a copper coin. In 1994, 33,200 tonnes (36,600 short tons) of zinc were used to produce 13.6 billion pennies in the United States.
answer:
What has zinc been replaced with in pipe organs?


question:
Passage: Migration plays an important role in Thuringia. The internal migration shows a strong tendency from rural areas towards the big cities. From 2008 to 2012, there was a net migration from Thuringia to Erfurt of +6,700 persons (33 per 1000 inhabitants), +1,800 to Gera (19 per 1000), +1,400 to Jena (14 per 1000), +1,400 to Eisenach (33 per 1000) and +1,300 to Weimar (21 per 1000). Between Thuringia and the other German states, the balance is negative: In 2012, Thuringia lost 6,500 persons to other federal states, the most to Bavaria, Saxony, Hesse and Berlin. Only with Saxony-Anhalt and Brandenburg the balance is positive. The international migration is fluctuating heavily. In 2009, the balance was +700, in 2010 +1,800, in 2011 +2,700 and in 2012 +4,800. The most important countries of origin of the Thuringia migrants from 2008 to 2012 were Poland (+1,700), Romania (+1,200), Afghanistan (+1,100) and Serbia/Montenegro/Kosovo (+1,000), whereas the balance was negative with Switzerland (−2,800) and Austria (−900).
