Problem: Please answer a question about the following article about British Empire:
By the start of the 20th century, Germany and the United States challenged Britain's economic lead. Subsequent military and economic tensions between Britain and Germany were major causes of the First World War, during which Britain relied heavily upon its empire. The conflict placed enormous strain on the military, financial and manpower resources of Britain. Although the British Empire achieved its largest territorial extent immediately after World War I, Britain was no longer the world's pre-eminent industrial or military power. In the Second World War, Britain's colonies in South-East Asia were occupied by Imperial Japan. Despite the final victory of Britain and its allies, the damage to British prestige helped to accelerate the decline of the empire. India, Britain's most valuable and populous possession, achieved independence as part of a larger decolonisation movement in which Britain granted independence to most territories of the Empire. The transfer of Hong Kong to China in 1997 marked for many the end of the British Empire. Fourteen overseas territories remain under British sovereignty. After independence, many former British colonies joined the Commonwealth of Nations, a free association of independent states. The United Kingdom is now one of 16 Commonwealth nations, a grouping known informally as the Commonwealth realms, that share one monarch—Queen Elizabeth II.
Which countries challenged Britain's economic lead by the start of the 20th century?
A: Germany and the United States

Problem: Please answer a question about the following article about FC Barcelona:
Despite being the favourites and starting strongly, Barcelona finished the 2006–07 season without trophies. A pre-season US tour was later blamed for a string of injuries to key players, including leading scorer Eto'o and rising star Lionel Messi. There was open feuding as Eto'o publicly criticized coach Frank Rijkaard and Ronaldinho. Ronaldinho also admitted that a lack of fitness affected his form. In La Liga, Barcelona were in first place for much of the season, but inconsistency in the New Year saw Real Madrid overtake them to become champions. Barcelona advanced to the semi-finals of the Copa del Rey, winning the first leg against Getafe 5–2, with a goal from Messi bringing comparison to Diego Maradona's goal of the century, but then lost the second leg 4–0. They took part in the 2006 FIFA Club World Cup, but were beaten by a late goal in the final against Brazilian side Internacional. In the Champions League, Barcelona were knocked out of the competition in the last 16 by eventual runners-up Liverpool on away goals.
What event was blamed for the injuries to Barcelona stars?
A:
US tour
