Problem: Croatian air pollution levels reflect the drop in industrial production recorded in 1991 at the onset of the Croatian War of Independence—pre-war emission levels were only reached in 1997. The use of Hydrodesulfurization fuels has led to a 25% reduction of sulphur dioxide emissions between 1997 and 2004, and a further 7.2% drop by 2007. The rise in NOx emissions halted in 2007 and reversed in 2008. The use of unleaded petrol reduced emissions of lead into the atmosphere by 91.5% between 1997 and 2004. Air quality measurements indicate that the air in rural areas is essentially clean, and in urban centres it generally complies with legal requirements. The most significant sources of greenhouse gas (GHG) emissions in Croatia are energy production (72%), industry (13%) and agriculture (11%). The average annual increase of GHG emissions is 3%, remaining within the Kyoto Protocol limits. Between 1990 and 2007, the use of Ozone depletion was reduced by 92%; their use is expected to be abolished by 2015.

How many years did it take for the reduction of sulphur dioxide emissions to drop by 25%?
Answer: 7
Q: According to the last national agricultural census, there were 1.6 million farms in 2010 (-32.4% since 2000) covering 12.7 million hectares (63% of which are located in Southern Italy). The vast majority (99%) are family-operated and small, averaging only 8 hectares in size. Of the total surface area in agricultural use (forestry excluded), grain fields take up 31%, olive tree orchards 8.2%, vineyards 5.4%, citrus orchards 3.8%, sugar beets 1.7%, and horticulture 2.4%. The remainder is primarily dedicated to pastures (25.9%) and feed grains (11.6%). The northern part of Italy produces primarily Maize, rice, sugar beets, soybeans, meat, fruits and dairy products, while the South specializes in wheat and citrus fruits. Livestock includes 6 million head of cattle, 8.6 million head of swine, 6.8 million head of sheep, and 0.9 million head of goats. The total annual production of the Fishing industry by country from capture and aquaculture, including crustaceans and molluscs, is around 480,000 tons.
How many percent of the farms are not located in Sweden?
A: 37
Problem: Sweden occupied the undefended Norwegian province of Jemtland, which was quickly reconquered by a counterattack by forces under command of the Norwegian governor of Trøndelag. The forces were unwilling to launch a counterattack on Swedish land. In 1564 the Swedes marched under Claude Collart and re-occupied Jemtland, as well as Herjedalen and Trøndelag, including the city of Trondheim. Initially facing little opposition from the locals, their subsequent ill treatment of the Trøndelag natives, along with tax pressure, laid the groundwork for later resistance to Swedish invasion. Also, Trøndelag was assisted by the governor of Bergenhus, Erik Rosenkrantz, who forced 3500 local peasants to assist him and his 50 professional soldiers. The Swedes saw Bergenhus as their next target. Although the 400 Swedish soldiers were repelled from Trøndelag, Sweden continued to occupy Jämtland and Härjedalen. These provinces were later regained by Denmark-Norway following the peace process in 1570. Sweden also launched attacks towards Eastern Norway. In the south-east Sweden captured Båhus Fortress, but lost it in 1566. Another part of the army marched through the valley Østerdalen in 1567, captured Hamar and continued towards Oslo. They reached as far as the Skiensfjord, and torched Skien at one point. In Oslo, however, citizens torched the city before invaders could seize it. From the south-east, more Swedish forces were then sent to aid in capturing Akershus Fortress near Oslo. These forces torched Konghelle and Sarpsborg on their way. They were repelled from Oslo by local forces together with men belonging to Erik Rosenkrantz and the King of Denmark and Norway. The Swedes retreated in a north-eastern direction, torching Hamar on their way, destroying Hamar Cathedral and the bishop's fortified palace Hamarhus.

Question:
Trying to snap a two-game skid, the Texans flew to Qualcomm Stadium for a Week 8 intraconference game against the San Diego Chargers.  In the first quarter, Houston's recent struggles continued as Chargers QB Philip Rivers completed a 49-yard TD pass to TE Antonio Gates.  Later, a goof-up on special teams led to more points as a high punt snap went into the end zone.  Punter Matt Turk was unable to fall on the ball and San Diego CB Antonio Cromartie managed to recover it for a touchdown.  In the second quarter, the Texans got on the board with kicker Kris Brown nailing a 40-yard field goal.  However, the Chargers continued their beatdown with Rivers and Gates hooking up again on a 31-yard TD pass.  Later, San Diego increased its lead with Cromartie returning an interception 70 yards for a touchdown, along with Rivers completing a 14-yard TD pass to WR Chris Chambers. After a scoreless third quarter, Houston tried to come back, as QB Sage Rosenfels completed a 28-yard TD to TE Joel Dreessen in the fourth quarter.  That was as close to the Chargers as they got. Starting QB Matt Schaub (11/18 for 77 yards and 2 interceptions) left the game in the second quarter with a concussion, after getting a late hit from San Diego CB Drayton Florence.

How many yards were each of Gates' touchdowns?

Answer:
49-yard
question: After a few years of peace, the Ottoman Empire attacked the Habsburg Empire again. The Turks almost captured Vienna, but king of Poland John III Sobieski led a Christian alliance that defeated them in the Battle of Vienna which shook the Ottoman Empire's hegemony in south-eastern Europe. A new Holy League was initiated by Pope Innocent XI and encompassed the Holy Roman Empire , the Venetian Republic and Poland in 1684, joined by Tsarist Russia in 1686. Ottomans suffered two decisive defeats against the Holy Roman Empire: the second Battle of Mohács in 1687 and a decade later, in 1697, the battle of Zenta. On the smaller Polish front, after the battles of 1683 , Sobieski, after his proposal for the League to state a major coordinated offensive, undertook a rather unsuccessful offensive in Moldavia in 1686, with the Ottomans refusing a major engagement and harassing the army. For the next four years Poland would blockade the key fortress at Kamenets, and Ottoman Tatars would raid the borderlands. In 1691, Sobieski undertook another expedition to Moldovia, with slightly better results, but still with no decisive victories. The last battle of the campaign was the battle of Podhajce in 1698, where Polish hetman Feliks Kazimierz Potocki defeated the Ottoman incursion into the Commonwealth. The League won the war in 1699 and forced the Ottoman Empire to sign the Treaty of Karlowitz. The Ottomans lost much of their European possessions, with Podolia  returned to Poland with imposion of Austria.
Answer this question: How many expeditions to Moldovia did Sobieski undertake?
answer:
2
