After World War II, two new competing formats came onto the market and gradually replaced the standard "78": the 33 1⁄3 rpm (often just referred to as the 33 rpm), and the 45 rpm (see above). The 33 1⁄3 rpm LP (for "long-play") format was developed by Columbia Records and marketed in June 1948. RCA Victor developed the 45 rpm format and marketed it in March 1949, each pursuing their own r&d in secret. Both types of new disc used narrower grooves, intended to be played with smaller stylus—typically 0.001 inches (25 µm) wide, compared to 0.003 inches (76 µm) for a 78—so the new records were sometimes called Microgroove. In the mid-1950s all record companies agreed to a common recording standard called RIAA equalization. Prior to the establishment of the standard each company used its own preferred standard, requiring discriminating listeners to use pre-amplifiers with multiple selectable equalization curves.
Who developed the 33 1/3 rpm LP?
A: Columbia Records

The U.S. Army currently consists of 10 active divisions as well as several independent units. The force is in the process of contracting after several years of growth. In June 2013, the Army announced plans to downsize to 32 active combat brigade teams by 2015 to match a reduction in active duty strength to 490,000 soldiers. Army Chief of Staff Raymond Odierno has projected that by 2018 the Army will eventually shrink to "450,000 in the active component, 335,000 in the National Guard and 195,000 in U.S. Army Reserve."
How many brigade teams did the Army downsize to by 2015?
A: 32

The Estonian Academy of Sciences is the national academy of science. The strongest public non-profit research institute that carries out fundamental and applied research is the National Institute of Chemical Physics and Biophysics (NICPB; Estonian KBFI). The first computer centres were established in the late 1950s in Tartu and Tallinn. Estonian specialists contributed in the development of software engineering standards for ministries of the Soviet Union during the 1980s. As of 2011[update], Estonia spends around 2.38% of its GDP on Research and Development, compared to an EU average of around 2.0%.
What is the strongest research body that executes fundamental and applied research?
A: the National Institute of Chemical Physics and Biophysics

The Early Triassic was between 250 million to 247 million years ago and was dominated by deserts as Pangaea had not yet broken up, thus the interior was nothing but arid. The Earth had just witnessed a massive die-off in which 95% of all life went extinct. The most common life on earth were Lystrosaurus, Labyrinthodont, and Euparkeria along with many other creatures that managed to survive the Great Dying. Temnospondyli evolved during this time and would be the dominant predator for much of the Triassic.
What species had evolved after  the extinction and would become the basic predator in the Triassic?
A:
Temnospondyli
