QUES: Officers may be commissioned upon graduation from the United States Air Force Academy, upon graduation from another college or university through the Air Force Reserve Officer Training Corps (AFROTC) program, or through the Air Force Officer Training School (OTS). OTS, previously located at Lackland AFB, Texas until 1993 and located at Maxwell Air Force Base in Montgomery, Alabama since 1993, in turn encompasses two separate commissioning programs: Basic Officer Training (BOT), which is for line-officer candidates of the active-duty Air Force and the U.S. Air Force Reserve; and the Academy of Military Science (AMS), which is for line-officer candidates of the Air National Guard. (The term "line officer" derives from the concept of the line of battle and refers to an officer whose role falls somewhere within the "Line of the Air", meaning combat or combat-support operations within the scope of legitimate combatants as defined by the Geneva Conventions.)

What is another program that allows officers to become commissioned in the USAF?
What is the answer?
ANS: Air Force Officer Training School
QUES: The immediate predecessors of MP3 were "Optimum Coding in the Frequency Domain" (OCF), and Perceptual Transform Coding (PXFM). These two codecs, along with block-switching contributions from Thomson-Brandt, were merged into a codec called ASPEC, which was submitted to MPEG, and which won the quality competition, but that was mistakenly rejected as too complex to implement. The first practical implementation of an audio perceptual coder (OCF) in hardware (Krasner's hardware was too cumbersome and slow for practical use), was an implementation of a psychoacoustic transform coder based on Motorola 56000 DSP chips.

Which competition did ASPEC win?
What is the answer?
ANS: quality
QUES: The islands enjoy a mild climate and varied soils, giving rise to a diverse pattern of vegetation. Animal and plant life is similar to that of the northwestern European continent. There are however, fewer numbers of species, with Ireland having even less. All native flora and fauna in Ireland is made up of species that migrated from elsewhere in Europe, and Great Britain in particular. The only window when this could have occurred was between the end of the last Ice Age (about 12,000 years ago) and when the land bridge connecting the two islands was flooded by sea (about 8,000 years ago).

The land bridge connecting two European continents was flooded by see about how many years ago?
