Given the task definition, example input & output, solve the new input case.
This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.
Example: Passage: The French and Indian War (17541763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.
Output: When was the French and Indian War?
This question is based on the following sentence in the passage- The French and Indian War (17541763) was the North American theater of the worldwide Seven Years' War. It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. You can ask questions like this one about dates, years, other numerals, persons, locations, noun phrases, verb phrases, adjectives, clauses etc. which exist in the paragraph.

New input case for you: During the 1930s, the first two motorways were built across the Land, the A4 motorway as an important east-west connection in central Germany and the main link between Berlin and south-west Germany, and the A9 motorway as the main north-south route in eastern Germany, connecting Berlin with Munich. The A4 runs from Frankfurt in Hesse via Eisenach, Gotha, Erfurt, Weimar, Jena and Gera to Dresden in Saxony, connecting Thuringia's most important cities. At Hermsdorf junction it is connected with the A9. Both highways were widened from four to six lanes (three each way) after 1990, including some extensive re-routing in the Eisenach and Jena areas. Furthermore, three new motorways were built during the 1990s and 2000s. The A71 crosses the Land in southwest-northeast direction, connecting Wurzburg in Bavaria via Meiningen, Suhl, Ilmenau, Arnstadt, Erfurt and Sommerda with Sangerhausen and Halle in Saxony-Anhalt. The crossing of the Thuringian Forest by the A71 has been one of Germany's most expensive motorway segments with various tunnels (including Germany's longest road tunnel, the Rennsteig Tunnel) and large bridges. The A73 starts at the A71 south of Erfurt in Suhl and runs south towards Nuremberg in Bavaria. The A38 is another west-east connection in the north of Thuringia running from Gottingen in Lower Saxony via Heiligenstadt and Nordhausen to Leipzig in Saxony. Furthermore, there is a dense network of federal highways complementing the motorway network. The upgrading of federal highways is prioritised in the federal trunk road programme 2015 (Bundesverkehrswegeplan 2015). Envisaged projects include upgrades of the B247 from Gotha to Leinefelde to improve Muhlhausen's connection to the national road network, the B19 from Eisenach to Meiningen to improve access to Bad Salzungen and Schmalkalden, and the B88 and B281 for strengthening the Saalfeld/Rudolstadt region.
Output:
When were the first motorways built in Thuringia?
