Problem: Ann Arbor, Michigan:

Pfizer, once the city's second largest employer, operated a large pharmaceutical research facility on the northeast side of Ann Arbor. On 22 January 2007, Pfizer announced it would close operations in Ann Arbor by the end of 2008. The facility was previously operated by Warner-Lambert and, before that, Parke-Davis. In December 2008, the University of Michigan Board of Regents approved the purchase of the facilities, and the university anticipates hiring 2,000 researchers and staff during the next 10 years. The city is the home of other research and engineering centers, including those of Lotus Engineering, General Dynamics and the National Oceanic and Atmospheric Administration (NOAA). Other research centers sited in the city are the United States Environmental Protection Agency's National Vehicle and Fuel Emissions Laboratory and the Toyota Technical Center. The city is also home to National Sanitation Foundation International (NSF International), the nonprofit non-governmental organization that develops generally accepted standards for a variety of public health related industries and subject areas.

Problem: In 1821, Mexico won its independence from Spain, and San Diego became part of the Mexican territory of Alta California. In 1822, Mexico began attempting to extend its authority over the coastal territory of Alta California. The fort on Presidio Hill was gradually abandoned, while the town of San Diego grew up on the level land below Presidio Hill. The Mission was secularized by the Mexican government in 1833, and most of the Mission lands were sold to wealthy Californio settlers. The 432 residents of the town petitioned the governor to form a pueblo, and Juan Maria Osuna was elected the first alcalde ("municipal magistrate"), defeating Pio Pico in the vote. (See, List of pre-statehood mayors of San Diego.) However, San Diego had been losing population throughout the 1830s and in 1838 the town lost its pueblo status because its size dropped to an estimated 100 to 150 residents. Beyond town Mexican land grants expanded the number of California ranchos that modestly added to the local economy.
What was the name of the Mexican territory San Diego became part of in 1812?

Context and question: Throughout the course of its life, a number of peripherals were released which added to the functionality of the SNES. Many of these devices were modeled after earlier add-ons for the NES: the Super Scope is a light gun functionally similar to the NES Zapper (though the Super Scope features wireless capabilities) and the Super Advantage is an arcade-style joystick with adjustable turbo settings akin to the NES Advantage. Nintendo also released the SNES Mouse in conjunction with its Mario Paint title. Hudson Soft, under license from Nintendo, released the Super Multitap, a multiplayer adapter for use with its popular series of Bomberman games. Some of the more unusual controllers include the BatterUP baseball bat, the Life Fitness Entertainment System (an exercise bike controller with built-in monitoring software), and the TeeV Golf golf club.
What type of accessory was the Super Scope?
Answer: light gun

Question: The Hellenistic period saw the rise of New Comedy, the only few surviving representative texts being those of Menander (born 342/1 BCE). Only one play, Dyskolos, survives in its entirety. The plots of this new Hellenistic comedy of manners were more domestic and formulaic, stereotypical low born characters such as slaves became more important, the language was colloquial and major motifs included escapism, marriage, romance and luck (Tyche). Though no Hellenistic tragedy remains intact, they were still widely produced during the period, yet it seems that there was no major breakthrough in style, remaining within the classical model. The Supplementum Hellenisticum, a modern collection of extant fragments, contains the fragments of 150 authors.
Is there an answer to this question: What is the name of the collection that holds fragments of works from 150 authors?

Answer: The Supplementum Hellenisticum

QUES: Unlike previous versions of Windows, Windows 8 was distributed at retail in "Upgrade" licenses only, which require an existing version of Windows to install. The "full version software" SKU, which was more expensive but could be installed on computers without an eligible OS or none at all, was discontinued. In lieu of full version, a specialized "System Builder" SKU was introduced. The "System Builder" SKU replaced the original equipment manufacturer (OEM) SKU, which was only allowed to be used on PCs meant for resale, but added a "Personal Use License" exemption that officially allowed its purchase and personal use by users on homebuilt computers.

What does OEM stand for?
