Problem: The Blitz:

Problem: Arsenal F.C.:

The largest shareholder on the Arsenal board is American sports tycoon Stan Kroenke. Kroenke first launched a bid for the club in April 2007, and faced competition for shares from Red and White Securities, which acquired its first shares off David Dein in August 2007. Red & White Securities was co-owned by Russian billionaire Alisher Usmanov and Iranian London-based financier Farhad Moshiri, though Usmanov bought Moshiri's stake in 2016. Kroenke came close to the 30% takeover threshold in November 2009, when he increased his holding to 18,594 shares (29.9%). In April 2011, Kroenke achieved a full takeover by purchasing the shareholdings of Nina Bracewell-Smith and Danny Fiszman, taking his shareholding to 62.89%. As of June 2015, Kroenke owns 41,698 shares (67.02%) and Red & White Securities own 18,695 shares (30.04%). Ivan Gazidis has been the club's Chief Executive since 2009.

Problem: Plymouth:

Along with the rest of South West England, Plymouth has a temperate oceanic climate (Koppen Cfb) which is generally wetter and milder than the rest of England. This means a wide range of exotic plants can be grown. The annual mean temperature is approximately 11 C (52 F). Due to the modifying effect of the sea the seasonal range is less than in most other parts of the UK. As a result of this summer highs are lower than its southerly latitude should warrant, but as a contrast the coldest month of February has mean minimum temperatures as mild as between 3 and 4 C (37 and 39 F). Snow is rare, not usually equating to more than a few flakes, but there have been exclusions, namely the European winter storms of 2009-10 which, in early January, covered Plymouth in at least 1 inch (2.5 cm) of snow; more on higher ground. Another period of notable snow occurred from 1719 December 2010 when up to 8 inches (20 cm) of snow fell through the period though only 2 inches (5.1 cm) would lie at any one time due to melt. Over the 19611990 period, annual snowfall accumulation averaged less than 7 cm (3 in) per year. July and August are the warmest months with mean daily maxima over 19 C (66 F).

Up to how many centimeters of snow fell on Plymouth between 17 and 19 December 2010?

A: 20
