QUES: Technologies based upon the polymerase chain reaction (PCR) method will become nearly ubiquitous gold standards of diagnostics of the near future, for several reasons. First, the catalog of infectious agents has grown to the point that virtually all of the significant infectious agents of the human population have been identified. Second, an infectious agent must grow within the human body to cause disease; essentially it must amplify its own nucleic acids in order to cause a disease. This amplification of nucleic acid in infected tissue offers an opportunity to detect the infectious agent by using PCR. Third, the essential tools for directing PCR, primers, are derived from the genomes of infectious agents, and with time those genomes will be known, if they are not already.

QUES: One elector in Minnesota cast a ballot for president with the name of "John Ewards" [sic] written on it. The Electoral College officials certified this ballot as a vote for John Edwards for president. The remaining nine electors cast ballots for John Kerry. All ten electors in the state cast ballots for John Edwards for vice president (John Edwards's name was spelled correctly on all ballots for vice president). This was the first time in U.S. history that an elector had cast a vote for the same person to be both president and vice president; another faithless elector in the 1800 election had voted twice for Aaron Burr, but under that electoral system only votes for the president's position were cast, with the runner-up in the Electoral College becoming vice president (and the second vote for Burr was discounted and re-assigned to Thomas Jefferson in any event, as it violated Electoral College rules).
How many times had Aaron Burr run for office in the past?

QUES: With the financial expansion, trading rights became more jealously guarded by the commercial elite. Towns saw the growing power of guilds, while on a national level special companies would be granted monopolies on particular trades, like the English wool Staple. The beneficiaries of these developments would accumulate immense wealth. Families like the Fuggers in Germany, the Medicis in Italy, the de la Poles in England, and individuals like Jacques Coeur in France would help finance the wars of kings, and achieve great political influence in the process.
Which economic associations gained power in the towns?

ANS: guilds

QUES: Blair announced in September 2006 that he would quit as leader within the year, though he had been under pressure to quit earlier than May 2007 in order to get a new leader in place before the May elections which were expected to be disastrous for Labour. In the event, the party did lose power in Scotland to a minority Scottish National Party government at the 2007 elections and, shortly after this, Blair resigned as Prime Minister and was replaced by his Chancellor, Gordon Brown. Although the party experienced a brief rise in the polls after this, its popularity soon slumped to its lowest level since the days of Michael Foot. During May 2008, Labour suffered heavy defeats in the London mayoral election, local elections and the loss in the Crewe and Nantwich by-election, culminating in the party registering its worst ever opinion poll result since records began in 1943, of 23%, with many citing Brown's leadership as a key factor. Membership of the party also reached a low ebb, falling to 156,205 by the end of 2009: over 40 per cent of the 405,000 peak reached in 1997 and thought to be the lowest total since the party was founded.
