Problem: Elizabeth II:

In May 2007, The Daily Telegraph, citing unnamed sources, reported that the Queen was "exasperated and frustrated" by the policies of the British Prime Minister, Tony Blair, that she was concerned the British Armed Forces were overstretched in Iraq and Afghanistan, and that she had raised concerns over rural and countryside issues with Blair. She was, however, said to admire Blair's efforts to achieve peace in Northern Ireland. On 20 March 2008, at the Church of Ireland St Patrick's Cathedral, Armagh, the Queen attended the first Maundy service held outside England and Wales. At the invitation of the Irish President, Mary McAleese, the Queen made the first state visit to the Republic of Ireland by a British monarch in May 2011.

Problem: The Premier League sells its television rights on a collective basis. This is in contrast to some other European Leagues, including La Liga, in which each club sells its rights individually, leading to a much higher share of the total income going to the top few clubs. The money is divided into three parts: half is divided equally between the clubs; one quarter is awarded on a merit basis based on final league position, the top club getting twenty times as much as the bottom club, and equal steps all the way down the table; the final quarter is paid out as facilities fees for games that are shown on television, with the top clubs generally receiving the largest shares of this. The income from overseas rights is divided equally between the twenty clubs.
Which clubs get the greatest share of broadcasting income when rights are sold individually?
---
Answer: the top few clubs

Problem: Antibiotics:

In 1939, coinciding with the start of World War II, Rene Dubos reported the discovery of the first naturally derived antibiotic, tyrothricin, a compound of 20% gramicidin and 80% tyrocidine, from B. brevis. It was one of the first commercially manufactured antibiotics universally and was very effective in treating wounds and ulcers during World War II. Gramicidin, however, could not be used systemically because of toxicity. Tyrocidine also proved too toxic for systemic usage. Research results obtained during that period were not shared between the Axis and the Allied powers during the war.

What was tyrothricin used for during toxicity?
