QUES: The Brookings Institution reported in June 2009 that U.S. consumption accounted for more than a third of the growth in global consumption between 2000 and 2007. "The US economy has been spending too much and borrowing too much for years and the rest of the world depended on the U.S. consumer as a source of global demand." With a recession in the U.S. and the increased savings rate of U.S. consumers, declines in growth elsewhere have been dramatic. For the first quarter of 2009, the annualized rate of decline in GDP was 14.4% in Germany, 15.2% in Japan, 7.4% in the UK, 18% in Latvia, 9.8% in the Euro area and 21.5% for Mexico.

What is one reason for the decline in growth around the world in 2009?
What is the answer?
ANS: recession in the U.S.

QUES: Gladstone returned to power after the 1892 general election; he was 82 years old. Victoria objected when Gladstone proposed appointing the Radical MP Henry Labouchere to the Cabinet, so Gladstone agreed not to appoint him. In 1894, Gladstone retired and, without consulting the outgoing prime minister, Victoria appointed Lord Rosebery as prime minister. His government was weak, and the following year Lord Salisbury replaced him. Salisbury remained prime minister for the remainder of Victoria's reign.
Who did Victoria appoint as Gladstone's succesor?

ANS: Lord Rosebery

Navigation is based on a variety of senses. Many birds have been shown to use a sun compass. Using the sun for direction involves the need for making compensation based on the time. Navigation has also been shown to be based on a combination of other abilities including the ability to detect magnetic fields (magnetoception), use visual landmarks as well as olfactory cues.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does using the sun for direction involve?
Ah, so.. the need for making compensation based on the time
