Problem: Adult contemporary music:

In 1989, Linda Ronstadt released Cry Like a Rainstorm, Howl Like the Wind, described by critics as "the first true Adult Contemporary album of the decade", featuring American soul singer Aaron Neville on several of the twelve tracks. The album was certified Triple Platinum in the United States alone and became a major success throughout the globe. The Grammy Award-winning singles, "Don't Know Much" and "All My Life", were both long-running #1 Adult Contemporary hits. Several additional singles from the disc made the AC Top 10 as well. The album won over many critics in the need to define AC, and appeared to change the tolerance and acceptance of AC music into mainstream day to day radio play.

Problem: The Sun (United Kingdom):

The Sun remained loyal to Thatcher right up to her resignation in November 1990, despite the party's fall in popularity over the previous year following the introduction of the Poll tax (officially known as the Community Charge). This change to the way local government is funded was vociferously supported by the newspaper, despite widespread opposition, (some from Conservative MPs), which is seen as having contributed to Thatcher's own downfall. The tax was quickly repealed by her successor John Major, whom The Sun initially supported enthusiastically, believing he was a radical Thatcherite – despite the economy having entered recession at this time.

How did The Sun feel about the Poll tax?

A: was vociferously supported by the newspaper


Problem: Renewable energy commercialization:

Setting national renewable energy targets can be an important part of a renewable energy policy and these targets are usually defined as a percentage of the primary energy and/or electricity generation mix. For example, the European Union has prescribed an indicative renewable energy target of 12 per cent of the total EU energy mix and 22 per cent of electricity consumption by 2010. National targets for individual EU Member States have also been set to meet the overall target. Other developed countries with defined national or regional targets include Australia, Canada, Israel, Japan, Korea, New Zealand, Norway, Singapore, Switzerland, and some US States.

 Name one other country without defined national or regional target?

A: unanswerable


Problem: London:

London's bus network is one of the largest in the world, running 24 hours a day, with about 8,500 buses, more than 700 bus routes and around 19,500 bus stops. In 2013, the network had more than 2 billion commuter trips per annum, more than the Underground. Around £850 million is taken in revenue each year.
