This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Example Input: Passage: During the 1970s the oil shocks (1973 oil crisis and 1979 energy crisis) hit Iceland hard. Inflation rose to 43% in 1974 and 59% in 1980, falling to 15% in 1987 but rising to 30% in 1988. Iceland experienced moderately strong GDP growth (3% on average) from 1995 to 2004. Growth slowed between 2000 and 2002, but the economy expanded by 4.3% in 2003 and grew by 6.2% in 2004. Growth in 2005 exceeded 6%. Inflation averaged merely 1.5% from 1993 to 1994, and only 1.7% from 1994 to 1995. Inflation over 2006 topped at 8.6%, with a rate of 6.9% as of January 2007. Standard & Poors reduced their rating for Iceland to AA- from A+ (long term) in December 2006, following a loosening of fiscal policy by the Icelandic government ahead of the 2007 elections. Foreign debt rose to more than five times the value of Icelands GDP, and Icelands Central Bank raised short-term interest rates to nearly 15% in 2007. Due to the plunging currency against the euro and dollar, in 2008 inflation was speculated to be at 20-25%.
Question: Which year was the inflation average higher, from 1993 to 1994 or 1994 to 1995?
Example Output: span

Example Input: Passage: The Senussi Campaign took place in North Africa, from November 1915 to February 1917, during the First World War between the British Empire and the Kingdom of Italy against the Senussi. The Senussi were a religious sect resident in Libya and Egypt, who were courted by the Ottoman Empire and the German Empire. In the summer of 1915, the Ottomans persuaded the Grand Senussi Ahmed Sharif as-Senussi to declare jihad, attack British-occupied Egypt from the west and encourage insurrection in Egypt, to divert British forces from an Ottoman Raid on the Suez Canal from Palestine. The Senussi crossed the Libyan-Egyptian border in November 1915 and fought a campaign along the Egyptian coast, where British Empire forces withdrew, then defeated the Senussi in several engagements, culminating in the Action of Agagia and the re-capture of the coast in March 1916. In the interior, the band of oases campaign continued until February 1917, after which a peace was negotiated and the area became quiet for the rest of the war, except for British patrols by aircraft and armoured cars.
Question: When did the Senussi Campaign start in North Africa?
Example Output: date

Example Input: Passage: The first recorded contact between Thailand  and the United States came in 1818, when an American ship captain visited the country, bearing a letter from U.S. President James Monroe. Chang and Eng Bunker immigrated in the early 1830s. In 1832, President Andrew Jackson sent his envoy Edmund Roberts in the U.S. sloop-of-war Peacock, to the courts of Cochin-China, Siam and Muscat. Roberts concluded a Treaty of Amity and Commerce on March 20, 1833, with the Chao-Phraya Phra Klang representing King Phra Nang Klao; ratifications exchanged April 14, 1836; proclaimed June 24, 1837. Naval surgeon William Ruschenberger accompanied the return mission for exchange of ratifications. His account and that of Mr. Roberts were collected, edited and re-published as Two Yankee Diplomats In 1830's Siam.  The 150th anniversary of Roberts' mission was marked by in 1982 by issuance  of the first edition of The Eagle and the Elephant: Thai-American relations since 1833, followed by multiple re-issues including a 1987 royal celebration edition and a 1997 golden jubilee edition.  This was affirmed by former prime minister Samak Sundaravej, who in 2008, met George W. Bush on the "occasion of the celebration of 175th anniversary of Thai-American relations." Thailand is thus the first Asian nation to have a formal diplomatic agreement with the United States; eleven years before the Great Qing and twenty-one years before Tokugawa Japan. In May  1856, Townsend Harris, a representative of President Franklin Pierce, negotiated a modified Treaty of Amity, Commerce, and Navigation with representatives of King Mongkut  that granted Americans additional extraterritorial rights.  Stephen Mattoon, an American missionary who acted as Harris's translator, was appointed the first United States consul  to Siam.
Question: How many years elapsed between the Roberts' mission, and the 150th anniversary?
