Problem: Hunting:

The Arabian oryx, a species of large antelope, once inhabited much of the desert areas of the Middle East. However, the species' striking appearance made it (along with the closely related scimitar-horned oryx and addax) a popular quarry for sport hunters, especially foreign executives of oil companies working in the region.[citation needed] The use of automobiles and high-powered rifles destroyed their only advantage: speed, and they became extinct in the wild exclusively due to sport hunting in 1972. The scimitar-horned oryx followed suit, while the addax became critically endangered. However, the Arabian oryx has now made a comeback and been upgraded from "extinct in the wild" to "vulnerable" due to conservation efforts like captive breeding

Problem: Orientation behaviour studies have been traditionally carried out using variants of a setup known as the Emlen funnel, which consists of a circular cage with the top covered by glass or wire-screen so that either the sky is visible or the setup is placed in a planetarium or with other controls on environmental cues. The orientation behaviour of the bird inside the cage is studied quantitatively using the distribution of marks that the bird leaves on the walls of the cage. Other approaches used in pigeon homing studies make use of the direction in which the bird vanishes on the horizon.
What does the bird leave on the walls of the cage?

Answer: marks

Since the Balfour Declaration of 1926 and the Statute of Westminster 1931, the all Commonwealth realms have been sovereign kingdoms, the monarch and governors-general acting solely on the advice of the local ministers who generally maintain the support of the legislature and are the ones who secure the passage of bills. They, therefore, are unlikely to advise the sovereign or his or her representative to withhold assent. The power to withhold the royal assent was exercised by Alberta's lieutenant governor, John C. Bowen, in 1937, in respect of three bills passed in the legislature dominated by William Aberhart's Social Credit party. Two bills sought to put banks under the authority of the province, thereby interfering with the federal government's powers. The third, the Accurate News and Information Bill, purported to force newspapers to print government rebuttals to stories to which the provincial cabinet objected. The unconstitutionality of all three bills was later confirmed by the Supreme Court of Canada and by the Judicial Committee of the Privy Council.
No Commonwealth realms are sovereign what?

Question: People of German origin are found in various places around the globe. United States is home to approximately 50 million German Americans or one third of the German diaspora, making it the largest centre of German-descended people outside Germany. Brazil is the second largest with 5 million people claiming German ancestry. Other significant centres are Canada, Argentina, South Africa and France each accounting for at least 1 million. While the exact number of German-descended people is difficult to calculate, the available data makes it safe to claim the number is exceeding 100 million people.
Is there an answer to this question: America is home to what percentage of German decedent people?

Answer: one third
