In a chapter of The Mathematical Foundations of Quantum Mechanics, von Neumann deeply analyzed the so-called measurement problem. He concluded that the entire physical universe could be made subject to the universal wave function. Since something "outside the calculation" was needed to collapse the wave function, von Neumann concluded that the collapse was caused by the consciousness of the experimenter (although this view was accepted by Eugene Wigner, the Von Neumann–Wigner interpretation never gained acceptance amongst the majority of physicists).
Were von Neumann's conclusions of collapse of entire universe cause accepted widely?
****
The answer: Von Neumann–Wigner interpretation never gained acceptance amongst the majority of physicists

Similar examples abound. Macedonian, although mutually intelligible with Bulgarian, certain dialects of Serbian and to a lesser extent the rest of the South Slavic dialect continuum, is considered by Bulgarian linguists to be a Bulgarian dialect, in contrast with the contemporary international view and the view in the Republic of Macedonia, which regards it as a language in its own right. Nevertheless, before the establishment of a literary standard of Macedonian in 1944, in most sources in and out of Bulgaria before the Second World War, the southern Slavonic dialect continuum covering the area of today's Republic of Macedonia were referred to as Bulgarian dialects.
In what year was a Macedonian literary standard established?
****
The answer: 1944

According to the U.S. Census Bureau, in 2004, Miami had the third highest incidence of family incomes below the federal poverty line in the United States, making it the third poorest city in the USA, behind only Detroit, Michigan (ranked #1) and El Paso, Texas (ranked #2). Miami is also one of the very few cities where its local government went bankrupt, in 2001. However, since that time, Miami has experienced a revival: in 2008, Miami was ranked as "America's Cleanest City" according to Forbes for its year-round good air quality, vast green spaces, clean drinking water, clean streets and city-wide recycling programs. In a 2009 UBS study of 73 world cities, Miami was ranked as the richest city in the United States (of four U.S. cities included in the survey) and the world's fifth-richest city, in terms of purchasing power.
As of 2004, what city was the poorest in the United States?
****
The answer: Detroit
