On 5 June 2008, Secretary of Defense Robert Gates, accepted the resignations of both the Secretary of the Air Force, Michael Wynne, and the Chief of Staff of the United States Air Force, General T. Michael Moseley. Gates in effect fired both men for "systemic issues associated with declining Air Force nuclear mission focus and performance." This followed an investigation into two embarrassing incidents involving mishandling of nuclear weapons: specifically a nuclear weapons incident aboard a B-52 flight between Minot AFB and Barksdale AFB, and an accidental shipment of nuclear weapons components to Taiwan. The resignations were also the culmination of disputes between the Air Force leadership, populated primarily by non-nuclear background fighter pilots, versus Gates. To put more emphasis on nuclear assets, the USAF established the nuclear-focused Air Force Global Strike Command on 24 October 2008.

Who was Robert Gates? 
Answer: Secretary of Defense

Internationally, Nigeria is infamous for a form of bank fraud dubbed 419, a type of advance fee fraud (named after Section 419 of the Nigerian Penal Code) along with the "Nigerian scam", a form of confidence trick practised by individuals and criminal syndicates. These scams involve a complicit Nigerian bank (the laws being set up loosely to allow it) and a scammer who claims to have money he needs to obtain from that bank. The victim is talked into exchanging bank account information on the premise that the money will be transferred to him, and then he'll get to keep a cut. In reality, money is taken out instead, and/or large fees (which seem small in comparison with the imaginary wealth he awaits) are deducted. In 2003, the Nigerian Economic and Financial Crimes Commission (or EFCC) was created, ostensibly to combat this and other forms of organised financial crime.

When was the Nigerian EFCC created?
Answer: 2003

Bird migration is primarily, but not entirely, a Northern Hemisphere phenomenon. This is because land birds in high northern latitudes, where food becomes scarce in winter, leave for areas further south (including the Southern Hemisphere) to overwinter, and because the continental landmass is much larger in the Northern Hemisphere. In contrast, among (pelagic) seabirds, species of the Southern Hemisphere are more likely to migrate. This is because there is a large area of ocean in the Southern Hemisphere, and more islands suitable for seabirds to nest.

Why are seabirds from the southern hemisphere more likely to migrate?
Answer:
there is a large area of ocean in the Southern Hemisphere
