Input: Read this: Hops contain several characteristics that brewers desire in beer. Hops contribute a bitterness that balances the sweetness of the malt; the bitterness of beers is measured on the International Bitterness Units scale. Hops contribute floral, citrus, and herbal aromas and flavours to beer. Hops have an antibiotic effect that favours the activity of brewer's yeast over less desirable microorganisms and aids in "head retention", the length of time that a foamy head created by carbonation will last. The acidity of hops is a preservative.
Question: What type of effect do floral hops have?

Output: unanswerable

QUES: The years following 2009 marked a shift in the structure of the "Big Four" with Tottenham Hotspur and Manchester City both breaking into the top four. In the 200910 season, Tottenham finished fourth and became the first team to break the top four since Everton in 2005. Criticism of the gap between an elite group of "super clubs" and the majority of the Premier League has continued, nevertheless, due to their increasing ability to spend more than the other Premier League clubs. Manchester City won the title in the 201112 season, becoming the first club outside the "Big Four" to win since 199495. That season also saw two of the Big Four (Chelsea and Liverpool) finish outside the top four places for the first time since 199495.

In which position did Tottenham finish in the 2009-10 season?
What is the answer?
ANS: fourth

The GDP of Thuringia is below the national average, in line with the other former East German Lands. Until 2004, Thuringia was one of the weakest regions within the European Union. The accession of several new countries, the crisis in southern Europe and the sustained economic growth in Germany since 2005 has brought the Thuringian GDP close to the EU average since then. The high economic subsidies granted by the federal government and the EU after 1990 are being reduced gradually and will end around 2020.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How long was Thuringia one of the strongest regions in the EU?
Ah, so.. unanswerable
