Input: Read this: In South Australia, initially a Liberal and Country Party affiliated party, the Liberal and Country League (LCL), mostly led by Premier of South Australia Tom Playford, was in power from the 1933 election to the 1965 election, though with assistance from an electoral malapportionment, or gerrymander, known as the Playmander. The LCL's Steele Hall governed for one term from the 1968 election to the 1970 election and during this time began the process of dismantling the Playmander. David Tonkin, as leader of the South Australian Division of the Liberal Party of Australia, became Premier at the 1979 election for one term, losing office at the 1982 election. The Liberals returned to power at the 1993 election, led by Premiers Dean Brown, John Olsen and Rob Kerin through two terms, until their defeat at the 2002 election. They have since remained in opposition under a record five Opposition Leaders.
Question: How long was Dean Brown in power?

Output: unanswerable

Input: Read this: In January 2009, the Green Power Partnership (GPP, sponsored by the EPA) listed Northwestern as one of the top 10 universities in the country in purchasing energy from renewable sources. The university matches 74 million kilowatt hours (kWh) of its annual energy use with Green-e Certified Renewable Energy Certificates (RECs). This green power commitment represents 30 percent of the university's total annual electricity use and places Northwestern in the EPA's Green Power Leadership Club. The 2010 Report by The Sustainable Endowments Institute awarded Northwestern a "B-" on its College Sustainability Report Card. The Initiative for Sustainability and Energy at Northwestern (ISEN), supporting research, teaching and outreach in these themes, was launched in 2008.
Question:  What grade was given to Northwestern on the 2011 College Sustainability Report Card by The Sustainable Endowments Institute?

Output: unanswerable


Input: Read this: Bomber crews already had some experience with these types of systems due to the deployment of the Lorenz beam, a commercial blind-landing aid which allowed aircraft to land at night or in bad weather. The Germans developed the short-range Lorenz system into the Knickebein aid, a system which used two Lorenz beams with much stronger signal transmissions. The concept was the same as the Lorenz system. Two aerials were rotated for the two converging beams which were pointed to cross directly over the target. The German bombers would attach themselves to either beam and fly along it until they started to pick up the signal from the other beam. When a continuous sound was heard from the second beam the crew knew they were above the target and began dropping their bombs.
Question: The Germans flew along one beam until they picked up the second beam the sound telling them when to start doing what?

Output:
dropping their bombs
