Problem: Early-years education is quite common in Thuringia. Since the 1950s, nearly all children have been using the service, whereas early-years education is less developed in western Germany. Its inventor Friedrich Frobel lived in Thuringia and founded the world's first Kindergartens there in the 19th century. The Thuringian primary school takes four years and most primary schools are all-day schools offering optional extracurricular activities in the afternoon. At the age of ten, pupils are separated according to aptitude and proceed to either the Gymnasium or the Regelschule. The former leads to the Abitur exam after a further eight years and prepares for higher education, while the latter has a more vocational focus and finishes with exams after five or six years, comparable to the Hauptschule and Realschule found elsewhere in Germany.
How long is Thuringian primary school?
The answer is the following: four years

Problem: Despite their close genetic relationship and the ability to inter-breed, there are a number of diagnostic features to distinguish the gray wolves from domestic dogs. Domesticated dogs are clearly distinguishable from wolves by starch gel electrophoresis of red blood cell acid phosphatase. The tympanic bullae are large, convex and almost spherical in gray wolves, while the bullae of dogs are smaller, compressed and slightly crumpled. Compared to equally sized wolves, dogs tend to have 20% smaller skulls and 30% smaller brains.:35 The teeth of gray wolves are also proportionately larger than those of dogs; the premolars and molars of wolves are much less crowded and have more complex cusp patterns. Wolves do not have dewclaws on their back legs, unless there has been admixture with dogs. Dogs lack a functioning pre-caudal gland, and most enter estrus twice yearly, unlike gray wolves which only do so once a year. Dogs require fewer calories to function than wolves. The dog's limp ears may be the result of atrophy of the jaw muscles. The skin of domestic dogs tends to be thicker than that of wolves, with some Inuit tribes favoring the former for use as clothing due to its greater resistance to wear and tear in harsh weather.
Dogs having ears that are not erect may be due to what?
The answer is the following: atrophy of the jaw muscles.

Problem: Victoria's father was Prince Edward, Duke of Kent and Strathearn, the fourth son of the reigning King of the United Kingdom, George III. Until 1817, Edward's niece, Princess Charlotte of Wales, was the only legitimate grandchild of George III. Her death in 1817 precipitated a succession crisis that brought pressure on the Duke of Kent and his unmarried brothers to marry and have children. In 1818 he married Princess Victoria of Saxe-Coburg-Saalfeld, a widowed German princess with two childrenCarl (18041856) and Feodora (18071872)by her first marriage to the Prince of Leiningen. Her brother Leopold was Princess Charlotte's widower. The Duke and Duchess of Kent's only child, Victoria, was born at 4.15 a.m. on 24 May 1819 at Kensington Palace in London.
Who was Princess Victoria widowed from?
The answer is the following: Prince of Leiningen

Problem: Alloying copper with tin to make bronze was first practiced about 4000 years after the discovery of copper smelting, and about 2000 years after "natural bronze" had come into general use[citation needed]. Bronze artifacts from the Vinca culture date to 4500 BC. Sumerian and Egyptian artifacts of copper and bronze alloys date to 3000 BC. The Bronze Age began in Southeastern Europe around 37003300 BC, in Northwestern Europe about 2500 BC. It ended with the beginning of the Iron Age, 20001000 BC in the Near East, 600 BC in Northern Europe. The transition between the Neolithic period and the Bronze Age was formerly termed the Chalcolithic period (copper-stone), with copper tools being used with stone tools. This term has gradually fallen out of favor because in some parts of the world the Chalcolithic and Neolithic are coterminous at both ends. Brass, an alloy of copper and zinc, is of much more recent origin. It was known to the Greeks, but became a significant supplement to bronze during the Roman Empire.
What was the transition between the Neolithic period and the bronze age called?
The answer is the following:
Chalcolithic
