In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.

Example input: Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lo during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Link Information: Operation Market Garden was a failed World War II military operation fought in the Netherlands from 17 to 25 September 1944. Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin?
Example output: from 17 to 25 September 1944
Example explanation: The passage describes the 704th's actions during Operation Market Garden, and the answer specifies when the operation happened.
Q: Passage: In 1998, Helmut Rix put forward the view that Etruscan is related to other members of what he called the "Tyrsenian language family". Rix's Tyrsenian family of languagescomposed of Raetic, anciently spoken in the eastern Alps, and Lemnian, together with Etruscanhas gained acceptance among scholars. Rix's Tyrsenian family has been confirmed by Stefan Schumacher, Norbert Oettinger, Carlo De Simone, and Simona Marchesini. Common features between Etruscan, Raetic, and Lemnian have been found in morphology, phonology, and syntax. On the other hand, lexical correspondences are rarely documented, due to the scant number of Raetic and Lemnian texts, and, above all, due to the very ancient date at which these languages split, because the split must have taken place before the Bronze Age. The Tyrsenian family, or Common Tyrrhenic, in this case is often considered to be Paleo-European and to predate the arrival of Indo-European languages in southern Europe. Several scholars believe that the Lemnian language could have arrived in the Aegean Sea during the Late Bronze Age, when Mycenaean rulers recruited groups of mercenaries from Sicily, Sardinia and various parts of the Italian peninsula. Scholars such as Norbert Oettinger, Michel Gras and Carlo De Simone think that the Lemnian is the testimony of an Etruscan piratesque or commercial settlement on the island that took place before 700 BC, not related to the Sea Peoples.
