Problem: Raleigh is home to numerous cultural, educational, and historic sites. The Duke Energy Center for the Performing Arts in Downtown Raleigh features three theater venues and serves as the home for the North Carolina Symphony and the Carolina Ballet. Walnut Creek Amphitheatre is a large music amphitheater located in Southeast Raleigh. Museums in Raleigh include the North Carolina Museum of Art in West Raleigh, as well as the North Carolina Museum of History and North Carolina Museum of Natural Sciences located next to each other near the State Capitol in Downtown Raleigh. Several major universities and colleges call Raleigh home, including North Carolina State University, the largest public university in the state, and Shaw University, the first historically black university in the American South and site of the foundation of the Student Nonviolent Coordinating Committee, an important civil rights organization of the 1960s. One U.S. president, Andrew Johnson, was born in Raleigh.
What energy center is downtown?
The answer is the following: Duke

Problem: Association football in itself does not have a classical history. Notwithstanding any similarities to other ball games played around the world FIFA have recognised that no historical connection exists with any game played in antiquity outside Europe. The modern rules of association football are based on the mid-19th century efforts to standardise the widely varying forms of football played in the public schools of England. The history of football in England dates back to at least the eighth century AD.
What organization has said that there is no historical connection to association football with any other game outside of Europe?
The answer is the following: FIFA

Problem: A person can be exposed to uranium (or its radioactive daughters, such as radon) by inhaling dust in air or by ingesting contaminated water and food. The amount of uranium in air is usually very small; however, people who work in factories that process phosphate fertilizers, live near government facilities that made or tested nuclear weapons, live or work near a modern battlefield where depleted uranium weapons have been used, or live or work near a coal-fired power plant, facilities that mine or process uranium ore, or enrich uranium for reactor fuel, may have increased exposure to uranium. Houses or structures that are over uranium deposits (either natural or man-made slag deposits) may have an increased incidence of exposure to radon gas. The Occupational Safety and Health Administration (OSHA) has set the permissible exposure limit for uranium exposure in the workplace as 0.25 mg/m3 over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 0.2 mg/m3 over an 8-hour workday and a short-term limit of 0.6 mg/m3. At levels of 10 mg/m3, uranium is immediately dangerous to life and health.
What is the OSHA uranium exposure limit for an 8-hour workday?
The answer is the following: 0.25 mg/m3

Problem: Because the electron mobility is higher than the hole mobility for all semiconductor materials, a given bipolar n–p–n transistor tends to be swifter than an equivalent p–n–p transistor. GaAs has the highest electron mobility of the three semiconductors. It is for this reason that GaAs is used in high-frequency applications. A relatively recent FET development, the high-electron-mobility transistor (HEMT), has a heterostructure (junction between different semiconductor materials) of aluminium gallium arsenide (AlGaAs)-gallium arsenide (GaAs) which has twice the electron mobility of a GaAs-metal barrier junction. Because of their high speed and low noise, HEMTs are used in satellite receivers working at frequencies around 12 GHz. HEMTs based on gallium nitride and aluminium gallium nitride (AlGaN/GaN HEMTs) provide a still higher electron mobility and are being developed for various applications.
What is quicker, a bipolar n-p-n transistor or a p-n-p transistor?
The answer is the following:
a given bipolar n–p–n transistor
