Example input: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? 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.

Q: Question: How long had the civil war been underway when Gorges returned? Passage:His signature appears as a witness on a document dated 1629 claiming to be a deed for the sale of land by Indians to a group of settlers led by John Wheelwright on the south side of the Piscataqua River in what is now New Hampshire. This document was alleged to be a forgery by 19th century historian James Savage, based in part on evidence that Vines was in England at the time of the sale. In 1630 he was definitely involved in the establishment of settlements around Cape Elizabeth, Maine as part of Gorges' efforts to establish the proprietary Province of Maine. Gorges did not receive a royal charter for the land and a commission as governor until 1639, at which time Gorges appointed his cousin Thomas as deputy governor. Thomas Gorges established the government of the colony, and in 1642 he and Vines led an exploratory expedition into the interior that reached as far as the White Mountains. Gorges returned to England in 1643 to fight in the English Civil War. Government of the colony devolved to a council, which elected Vines deputy governor in 1644. Vines governed until 1645, during which time the colony was involved in conflicting land claims of the Lygonia territory administered by George Cleeve.
