Problem: Cork (city):

The Cork area has seen improvements in road infrastructure in recent years. For example, the Cork South Link dual carriageway was built in the early 1980s, to link the Kinsale Road roundabout with the city centre. Shortly afterwards, the first sections of the South Ring dual carriageway were opened. Work continued through the 1990s on extending the N25 South Ring Road, with the opening of the Jack Lynch Tunnel under the River Lee being a significant addition. The Kinsale Road flyover opened in August 2006 to remove a bottleneck for traffic heading to Cork Airport or Killarney. Other projects completed at this time include the N20 Blackpool bypass and the N20 Cork to Mallow road projects. The N22 Ballincollig dual carriageway bypass, which links to the Western end of the Cork Southern Ring road was opened in September 2004. City Centre road improvements include the Patrick Street project - which reconstructed the street with a pedestrian focus. The M8 motorway links Cork with Dublin.

Problem: Sichuan:

The existence of the early state of Shu was poorly recorded in the main historical records of China. It was, however, referred to in the Book of Documents as an ally of the Zhou. Accounts of Shu exist mainly as a mixture of mythological stories and historical legends recorded in local annals such as the Chronicles of Huayang compiled in the Jin dynasty (265420), with folk stories such as that of Emperor Duyu () who taught the people agriculture and transformed himself into a cuckoo after his death. The existence of a highly developed civilization with an independent bronze industry in Sichuan eventually came to light with an archaeological discovery in 1986 at a small village named Sanxingdui in Guanghan, Sichuan. This site, believed to be an ancient city of Shu, was initially discovered by a local farmer in 1929 who found jade and stone artefacts. Excavations by archaeologists in the area yielded few significant finds until 1986 when two major sacrificial pits were found with spectacular bronze items as well as artefacts in jade, gold, earthenware, and stone. This and other discoveries in Sichuan contest the conventional historiography that the local culture and technology of Sichuan were undeveloped in comparison to the technologically and culturally "advanced" Yellow River valley of north-central China. The name Shu continues to be used to refer to Sichuan in subsequent periods in Chinese history up to the present day.

Problem: Prime minister:

She remained continuously in power until 1990, though she used the assembly of each House of Commons after a general election to reshuffle her cabinet.
