QUES: For decades after the Second World War, any national symbol or expression was a taboo. However, the Germans are becoming increasingly patriotic. During a study in 2009, in which some 2,000 German citizens age 14 and upwards filled out a questionnaire, nearly 60% of those surveyed agreed with the sentiment "I'm proud to be German." And 78%, if free to choose their nation, would opt for German nationality with "near or absolute certainty". Another study in 2009, carried out by the Identity Foundation in Düsseldorf, showed that 73% of the Germans were proud of their country, twice more than 8 years earlier. According to Eugen Buss, a sociology professor at the University of Hohenheim, there's an ongoing normalisation and more and more Germans are becoming openly proud of their country.
What war was followed by an increase in national symbols?

QUES: In free-range husbandry, the birds can roam freely outdoors for at least part of the day. Often, this is in large enclosures, but the birds have access to natural conditions and can exhibit their normal behaviours. A more intensive system is yarding, in which the birds have access to a fenced yard and poultry house at a higher stocking rate. Poultry can also be kept in a barn system, with no access to the open air, but with the ability to move around freely inside the building. The most intensive system for egg-laying chickens is battery cages, often set in multiple tiers. In these, several birds share a small cage which restricts their ability to move around and behave in a normal manner. The eggs are laid on the floor of the cage and roll into troughs outside for ease of collection. Battery cages for hens have been illegal in the EU since January 1, 2012.
When did battery cages become the only way to house hens?

ANS: unanswerable
