Problem: Education in the Bronx is provided by a large number of public and private institutions, many of which draw students who live beyond the Bronx. The New York City Department of Education manages public noncharter schools in the borough. In 2000, public schools enrolled nearly 280,000 of the Bronx's residents over 3 years old (out of 333,100 enrolled in all pre-college schools). There are also several public charter schools. Private schools range from elite independent schools to religiously affiliated schools run by the Roman Catholic Archdiocese of New York and Jewish organizations.
How many students attended the Bronx public noncharter schools as of 2000?
The answer is the following: nearly 280,000

Problem: Energy gives rise to weight when it is trapped in a system with zero momentum, where it can be weighed. It is also equivalent to mass, and this mass is always associated with it. Mass is also equivalent to a certain amount of energy, and likewise always appears associated with it, as described in mass-energy equivalence. The formula E = mc, derived by Albert Einstein (1905) quantifies the relationship between rest-mass and rest-energy within the concept of special relativity. In different theoretical frameworks, similar formulas were derived by J. J. Thomson (1881), Henri Poincare (1900), Friedrich Hasenohrl (1904) and others (see Mass-energy equivalence#History for further information).
When does energy give rise to weight?
The answer is the following: when it is trapped in a system with zero momentum

Problem: China is the largest unitary state in the world by both population and land area. Although China has had long periods of central rule for centuries, it is often argued that the unitary structure of the Chinese government is far too unwieldy to effectively and equitably manage the country's affairs. On the other hand, Chinese nationalists are suspicious of decentralization as a form of secessionism and a backdoor for national disunity; still others argue that the degree of autonomy given to provincial-level officials in the People's Republic of China amounts to a de facto federalism.
What are Chinese nationalist suspicious of?
The answer is the following: decentralization

Problem: In addition to basic uniform clothing, various badges are used by the USAF to indicate a billet assignment or qualification-level for a given assignment. Badges can also be used as merit-based or service-based awards. Over time, various badges have been discontinued and are no longer distributed. Authorized badges include the Shields of USAF Fire Protection, and Security Forces, and the Missile Badge (or "pocket rocket"), which is earned after working in a missile system maintenance or missile operations capacity for at least one year.
When is the special "pocket rocket" badge given to USAF personnel working in a missile system operation?
The answer is the following:
at least one year
