Problem: The Blitz:

Whitehall's disquiet at the failures of the RAF led to the replacement of Dowding (who was already due for retirement) with Sholto Douglas on 25 November. Douglas set about introducing more squadrons and dispersing the few GL sets to create a carpet effect in the southern counties. Still, in February 1941, there remained only seven squadrons with 87 pilots, under half the required strength. The GL carpet was supported by six GCI sets controlling radar-equipped night-fighters. By the height of the Blitz, they were becoming more successful. The number of contacts and combats rose in 1941, from 44 and two in 48 sorties in January 1941, to 204 and 74 in May (643 sorties). But even in May, 67% of the sorties were visual cat's-eye missions. Curiously, while 43% of the contacts in May 1941 were by visual sightings, they accounted for 61% of the combats. Yet when compared with Luftwaffe daylight operations, there was a sharp decline in German losses to 1%. If a vigilant bomber crew could spot the fighter first, they had a decent chance at evading it.

Problem: Cork (city):

The city is also the home of road bowling, which is played in the north-side and south-west suburbs. There are also boxing and martial arts clubs (including Brazilian jiu-jitsu, Karate, Muay Thai and Taekwondo) within the city. Cork Racing, a motorsport team based in Cork, has raced in the Irish Formula Ford Championship since 2005.

Problem: Strasbourg:

City transportation in Strasbourg includes the futurist-looking Strasbourg tramway that opened in 1994 and is operated by the regional transit company Compagnie des Transports Strasbourgeois (CTS), consisting of 6 lines with a total length of 55.8 km (34.7 mi). The CTS also operates a comprehensive bus network throughout the city that is integrated with the trams. With more than 500 km (311 mi) of bicycle paths, biking in the city is convenient and the CTS operates a cheap bike-sharing scheme named Velhop'. The CTS, and its predecessors, also operated a previous generation of tram system between 1878 and 1960, complemented by trolleybus routes between 1939 and 1962.
