Problem: The British dealt with range measurement first, when it was realised that range was the key to producing a better fuse setting. This led to the Height/Range Finder (HRF), the first model being the Barr & Stroud UB2, a 2-metre optical coincident rangefinder mounted on a tripod. It measured the distance to the target and the elevation angle, which together gave the height of the aircraft. These were complex instruments and various other methods were also used. The HRF was soon joined by the Height/Fuse Indicator (HFI), this was marked with elevation angles and height lines overlaid with fuse length curves, using the height reported by the HRF operator, the necessary fuse length could be read off.
What helped with better fuse setting?
The answer is the following: range measurement

Colour broadcasts started at similarly higher resolutions, first with the US NTSC color system in 1953, which was compatible with the earlier monochrome systems and therefore had the same 525 lines of resolution. European standards did not follow until the 1960s, when the PAL and SECAM color systems were added to the monochrome 625 line broadcasts.
What year did color broadcasts start in the US?

Input: Middle Ages
In the Eastern Empire the slow infiltration of the Balkans by the Slavs added a further difficulty for Justinian's successors. It began gradually, but by the late 540s Slavic tribes were in Thrace and Illyrium, and had defeated an imperial army near Adrianople in 551. In the 560s the Avars began to expand from their base on the north bank of the Danube; by the end of the 6th century they were the dominant power in Central Europe and routinely able to force the eastern emperors to pay tribute. They remained a strong power until 796. An additional problem to face the empire came as a result of the involvement of Emperor Maurice (r. 582602) in Persian politics when he intervened in a succession dispute. This led to a period of peace, but when Maurice was overthrown, the Persians invaded and during the reign of Emperor Heraclius (r. 610641) controlled large chunks of the empire, including Egypt, Syria, and Asia Minor, until Heraclius' successful counterattack. In 628 the empire secured a peace treaty and recovered all of its lost territories.

Near what river were the Avars originally based?
Output: the Danube

Input: Article: The Great Depression ended at different times in different countries with the effect lasting into the next era. America's Great Depression ended in 1941 with America's entry into World War II. The majority of countries set up relief programs, and most underwent some sort of political upheaval, pushing them to the left or right. In some world states, the desperate citizens turned toward nationalist demagoguesthe most infamous being Adolf Hitlersetting the stage for the next era of war. The convulsion brought on by the worldwide depression resulted in the rise of Nazism. In Asia, Japan became an ever more assertive power, especially with regards to China.

Now answer this question: When did Americas Great Depression end?

Output: 1941

Article: In its early years of existence, the smooth jazz format was considered to be a form of AC, although it was mainly instrumental, and related a stronger resemblance to the soft AC-styled music.
