Problem: Melbourne's air quality is generally good and has improved significantly since the 1980s. Like many urban environments, the city faces significant environmental issues, many of them relating to the city's large urban footprint and urban sprawl and the demand for infrastructure and services. One such issue is water usage, drought and low rainfall. Drought in Victoria, low rainfalls and high temperatures deplete Melbourne water supplies and climate change may have a long-term impact on the water supplies of Melbourne. In response to low water supplies and low rainfall due to drought, the government implemented water restrictions and a range of other options including: water recycling schemes for the city, incentives for household water tanks, greywater systems, water consumption awareness initiatives, and other water saving and reuse initiatives; also, in June 2007, the Bracks Government announced that a $3.1 billion Wonthaggi desalination plant would be built on Victoria's south-east coast, capable of treating 150 billion litres of water per year, as well as a 70 km (43 mi) pipeline from the Goulburn area in Victoria's north to Melbourne and a new water pipeline linking Melbourne and Geelong. Both projects are being conducted under controversial Public-Private Partnerships and a multitude of independent reports have found that neither project is required to supply water to the city and that Sustainable Water Management is the best solution. In the meantime, the drought must be weathered.
Has Melbourne's air quality improved or declined since the 1980s?
The answer is the following: improved significantly

Problem: In response to concerns that clubs were increasingly passing over young English players in favour of foreign players, in 1999, the Home Office tightened its rules for granting work permits to players from countries outside of the European Union. A non-EU player applying for the permit must have played for his country in at least 75 per cent of its competitive 'A' team matches for which he was available for selection during the previous two years, and his country must have averaged at least 70th place in the official FIFA world rankings over the previous two years. If a player does not meet those criteria, the club wishing to sign him may appeal.
In which year did the Home Office tighten rules on granting work permits to foreign football players?
The answer is the following: 1999

Problem: The Wagner tuba, a modified member of the horn family, appears in Richard Wagner's cycle Der Ring des Nibelungen and several other works by Strauss, Béla Bartók, and others; it has a prominent role in Anton Bruckner's Symphony No. 7 in E Major. Cornets appear in Pyotr Ilyich Tchaikovsky's ballet Swan Lake, Claude Debussy's La Mer, and several orchestral works by Hector Berlioz. Unless these instruments are played by members doubling on another instrument (for example, a trombone player changing to euphonium for a certain passage), orchestras will use freelance musicians to augment their regular rosters.
What is the name of the modified member of the horn family appearing in several works by Strauss?
The answer is the following:
The Wagner tuba
