QUES: Mac OS continued to evolve up to version 9.2.2, including retrofits such as the addition of a nanokernel and support for Multiprocessing Services 2.0 in Mac OS 8.6, though its dated architecture made replacement necessary. Initially developed in the Pascal programming language, it was substantially rewritten in C++ for System 7. From its beginnings on an 8 MHz machine with 128 KB of RAM, it had grown to support Apple's latest 1 GHz G4-equipped Macs. Since its architecture was laid down, features that were already common on Apple's competition, like preemptive multitasking and protected memory, had become feasible on the kind of hardware Apple manufactured. As such, Apple introduced Mac OS X, a fully overhauled Unix-based successor to Mac OS 9. OS X uses Darwin, XNU, and Mach as foundations, and is based on NeXTSTEP. It was released to the public in September 2000, as the Mac OS X Public Beta, featuring a revamped user interface called "Aqua". At US$29.99, it allowed adventurous Mac users to sample Apple's new operating system and provide feedback for the actual release. The initial version of Mac OS X, 10.0 "Cheetah", was released on March 24, 2001. Older Mac OS applications could still run under early Mac OS X versions, using an environment called "Classic". Subsequent releases of Mac OS X included 10.1 "Puma" (2001), 10.2 "Jaguar" (2002), 10.3 "Panther" (2003) and 10.4 "Tiger" (2005).
What programming language was the Mac OS initially developed in?

ANS: Pascal

QUES: Carnival is celebrated in New York City in Brooklyn. As in the UK, the timing of Carnival split from the Christian calendar and is celebrated on Labor Day Monday, in September. It is called the Labor Day Carnival, West Indian Day Parade or West Indian Day Carnival, and was founded by immigrants from Trinidad. That country has one of the largest Caribbean Carnivals.

QUES: In 1960, non-Hispanic whites represented 80% of Miami-Dade county's population. In 1970, the Census Bureau reported Miami's population as 45.3% Hispanic, 32.9% non-Hispanic White, and 22.7% Black. Miami's explosive population growth has been driven by internal migration from other parts of the country, primarily up until the 1980s, as well as by immigration, primarily from the 1960s to the 1990s. Today, immigration to Miami has slowed significantly and Miami's growth today is attributed greatly to its fast urbanization and high-rise construction, which has increased its inner city neighborhood population densities, such as in Downtown, Brickell, and Edgewater, where one area in Downtown alone saw a 2,069% increase in population in the 2010 Census. Miami is regarded as more of a multicultural mosaic, than it is a melting pot, with residents still maintaining much of, or some of their cultural traits. The overall culture of Miami is heavily influenced by its large population of Hispanics and blacks mainly from the Caribbean islands.
Along with Downtown and Edgewater, what area of Miami has notably seen increasing population densities?

ANS: Brickell

QUES: The Washington National Records Center (WNRC), located in Suitland, Maryland is a large warehouse type facility which stores federal records which are still under the control of the creating agency. Federal government agencies pay a yearly fee for storage at the facility. In accordance with federal records schedules, documents at WNRC are transferred to the legal custody of the National Archives after a certain point (this usually involves a relocation of the records to College Park). Temporary records at WNRC are either retained for a fee or destroyed after retention times has elapsed. WNRC also offers research services and maintains a small research room.
What happens to temporary records at the WNRC if they are not retrieved by the end of the retention times?

ANS:
destroyed
