Problem: In 1991, several manufacturers announced specifications for what would become known as MUSE LaserDisc, representing a span of almost 15 years until the feats of this HD analog optical disc system would finally be duplicated digitally by HD DVD and Blu-ray Disc. Encoded using NHK's MUSE "Hi-Vision" analogue TV system, MUSE discs would operate like standard LaserDiscs but would contain high-definition 1,125-line (1,035 visible lines) (Sony HDVS) video with a 5:3 aspect ratio. The MUSE players were also capable of playing standard NTSC format discs and are superior in performance to non-MUSE players even with these NTSC discs. The MUSE-capable players had several noteworthy advantages over standard LaserDisc players, including a red laser with a much narrower wavelength than the lasers found in standard players. The red laser was capable of reading through disc defects such as scratches and even mild disc rot that would cause most other players to stop, stutter or drop-out. Crosstalk was not an issue with MUSE discs, and the narrow wavelength of the laser allowed for the virtual elimination of crosstalk with normal discs.
What benefits did the MUSE narrow wavelength red laser have?
The answer is the following: capable of reading through disc defects such as scratches and even mild disc rot that would cause most other players to stop, stutter or drop-out

Problem: As an important railroad and road junction and production center, Hanover was a major target for strategic bombing during World War II, including the Oil Campaign. Targets included the AFA (Stocken), the Deurag-Nerag refinery (Misburg), the Continental plants (Vahrenwald and Limmer), the United light metal works (VLW) in Ricklingen and Laatzen (today Hanover fairground), the Hanover/Limmer rubber reclamation plant, the Hanomag factory (Linden) and the tank factory M.N.H. Maschinenfabrik Niedersachsen (Badenstedt). Forced labourers were sometimes used from the Hannover-Misburg subcamp of the Neuengamme concentration camp. Residential areas were also targeted, and more than 6,000 civilians were killed by the Allied bombing raids. More than 90% of the city center was destroyed in a total of 88 bombing raids. After the war, the Aegidienkirche was not rebuilt and its ruins were left as a war memorial.
How many civilians were killed in the Allied bombing raids in World War II?
The answer is the following: more than 6,000

Problem: In 1997, OMB issued a Federal Register notice regarding revisions to the standards for the classification of federal data on race and ethnicity. OMB developed race and ethnic standards in order to provide "consistent data on race and ethnicity throughout the Federal Government. The development of the data standards stem in large measure from new responsibilities to enforce civil rights laws." Among the changes, OMB issued the instruction to "mark one or more races" after noting evidence of increasing numbers of interracial children and wanting to capture the diversity in a measurable way and having received requests by people who wanted to be able to acknowledge their or their children's full ancestry rather than identifying with only one group. Prior to this decision, the Census and other government data collections asked people to report only one race.
How many races were people asked to report in the US census prior to 1997?
The answer is the following: one

Problem: On 7 January 2015, two French Muslim extremists attacked the Paris headquarters of Charlie Hebdo and killed thirteen people, and on 9 January, a third terrorist killed four hostages during an attack at a Jewish grocery store at Porte de Vincennes. On 11 January an estimated 1.5 million people marched in Parisalong with international political leadersto show solidarity against terrorism and in defence of freedom of speech.

Seven of the attackers killed themselves and others by setting off their explosive vests. On the morning of 18 November three suspected terrorists, including alleged planner of the attacks Abdelhamid Abaaoud, were killed in a shootout with police in the Paris suburb of Saint-Denis. President Hollande declared France to be in a three-month state of emergency.
How many people marched on January 11 against terrorism?
The answer is the following:
1.5 million
