Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: How many months/years passed between the signing of the Adams-Onis Treaty and the acquisition of Florida? Passage:Born in Braintree, Massachusetts, Adams spent much of his youth in Europe, where his father served as a diplomat. After returning to the United States, Adams established a successful legal practice in Boston. In 1794, President George Washington appointed Adams as the U.S. ambassador to the Netherlands, and Adams would serve in high-ranking diplomatic posts until 1801, when Thomas Jefferson took office as president. Federalist leaders in Massachusetts arranged for Adams's election to the United States Senate in 1802, but Adams broke with the Federalist Party over foreign policy and was denied re-election. In 1809, Adams was appointed as the U.S. ambassador to Russia by President James Madison, a member of the Democratic-Republican Party. Adams held diplomatic posts for the duration of Madison's presidency, and he served as part of the American delegation that negotiated an end to the War of 1812. In 1817, newly-elected President James Monroe selected Adams as his Secretary of State. In that role, Adams negotiated the AdamsOnis Treaty, which provided for the American acquisition of Florida. He also helped formulate the Monroe Doctrine, which became a key tenet of U.S. foreign policy.

Example Input: Question: During which centuries were the Kyoto Imperial Palace and the Sento Imperial Palace home to the Emperors of Japan? Passage:With its 2,000 religious places 1,600 Buddhist temples and 400 Shinto shrines, as well as palaces, gardens and architecture intact it is one of the best preserved cities in Japan. Among the most famous temples in Japan are Kiyomizu-dera, a magnificent wooden temple supported by pillars off the slope of a mountain; Kinkaku-ji, the Temple of the Golden Pavilion; Ginkaku-ji, the Temple of the Silver Pavilion; and Ryoan-ji, famous for its rock garden. The Heian Jingu is a Shinto shrine, built in 1895, celebrating the Imperial family and commemorating the first and last emperors to reside in Kyoto. Three special sites have connections to the imperial family: the Kyoto Gyoen area including the Kyoto Imperial Palace and Sento Imperial Palace, homes of the Emperors of Japan for many centuries; Katsura Imperial Villa, one of the nation's finest architectural treasures; and Shugaku-in Imperial Villa, one of its best Japanese gardens.

Example Input: 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.
