Problem: Please answer a question about the following article about Planck constant:
There are both practical and theoretical difficulties in determining h. The practical difficulties can be illustrated by the fact that the two most accurate methods, the watt balance and the X-ray crystal density method, do not appear to agree with one another. The most likely reason is that the measurement uncertainty for one (or both) of the methods has been estimated too low – it is (or they are) not as precise as is currently believed – but for the time being there is no indication which method is at fault.
Why does this difficulty occur?
A: it is (or they are) not as precise as is currently believed

Police development-aid to weak, failed or failing states is another form of transnational policing that has garnered attention. This form of transnational policing plays an increasingly important role in United Nations peacekeeping and this looks set to grow in the years ahead, especially as the international community seeks to develop the rule of law and reform security institutions in States recovering from conflict (Goldsmith and Sheptycki, 2007) With transnational police development-aid the imbalances of power between donors and recipients are stark and there are questions about the applicability and transportability of policing models between jurisdictions (Hills, 2009).

What kind of countries get assistance with policing?
Answer: weak, failed or failing states


Problem: The consuls of the Roman Republic were the highest ranking ordinary magistrates; each consul served for one year. Consuls had supreme power in both civil and military matters. While in the city of Rome, the consuls were the head of the Roman government. They would preside over the senate and the assemblies. While abroad, each consul would command an army. His authority abroad would be nearly absolute. Praetors administered civil law and commanded provincial armies. Every five years, two censors were elected for an 18-month term, during which they would conduct a census. During the census, they could enroll citizens in the senate, or purge them from the senate. Aediles were officers elected to conduct domestic affairs in Rome, such as managing public games and shows. The quaestors would usually assist the consuls in Rome, and the governors in the provinces. Their duties were often financial.
Which official had supremacy in both civil and military matters?
The answer is the following: Consuls


Though government support for universities declined in the 1970s and 1980s, President Arnold R. Weber was able to stabilize university finances, leading to a revitalization of the campuses. As admissions to colleges and universities grew increasingly competitive in the 1990s and 2000s, President Henry S. Bienen's tenure saw a notable increase in the number and quality of undergraduate applicants, continued expansion of the facilities and faculty, and renewed athletic competitiveness. In 1999, Northwestern student journalists uncovered information exonerating Illinois death row inmate Anthony Porter two days before his scheduled execution, and the Innocence Project has since exonerated 10 more men. On January 11, 2003, in a speech at Northwestern School of Law's Lincoln Hall, then Governor of Illinois George Ryan announced that he would commute the sentences of more than 150 death row inmates.
What was President Arnold R. Weber able to do with Northwestern's finances as the government's support of universities declined in the 70's and 80's?
stabilize

Problem: Please answer a question about the following article about John von Neumann:
Von Neumann's mathematical analysis of the structure of self-replication preceded the discovery of the structure of DNA. In a short list of facts about his life he submitted to the National Academy of Sciences, he stated "The part of my work I consider most essential is that on quantum mechanics, which developed in Göttingen in 1926, and subsequently in Berlin in 1927–1929. Also, my work on various forms of operator theory, Berlin 1930 and Princeton 1935–1939; on the ergodic theorem, Princeton, 1931–1932."
Where was quantum mechanics developed?
A:
Göttingen
