Input: Consider Input: Near the intersection of Craycroft and Ft. Lowell Roads are the remnants of the Historic Fort Lowell. This area has become one of Tucson's iconic neighborhoods. In 1891, the Fort was abandoned and much of the interior was stripped of their useful components and it quickly fell into ruin. In 1900, three of the officer buildings were purchased for use as a sanitarium. The sanitarium was then sold to Harvey Adkins in 1928. The Bolsius family Pete, Nan and Charles Bolsius purchased and renovated surviving adobe buildings of the Fort – transforming them into spectacular artistic southwestern architectural examples. Their woodwork, plaster treatment and sense of proportion drew on their Dutch heritage and New Mexican experience. Other artists and academics throughout the middle of the 20th century, including: Win Ellis, Jack Maul, Madame Cheruy, Giorgio Belloli, Charels Bode, Veronica Hughart, Edward and Rosamond Spicer, Hazel Larson Archer and Ruth Brown, renovated adobes, built homes and lived in the area. The artist colony attracted writers and poets including beat generation Alan Harrington and Jack Kerouac whose visit is documented in his iconic book On the Road. This rural pocket in the middle of the city is listed on the National Register of Historic Places. Each year in February the neighborhood celebrates its history in the City Landmark it owns and restored the San Pedro Chapel.

Output: Who bought The sanitarium in 1928?


Input: Consider Input: Honors and tributes flowed to Bell in increasing numbers as his most famous invention became ubiquitous and his personal fame grew. Bell received numerous honorary degrees from colleges and universities, to the point that the requests almost became burdensome.

Input: Consider Input: In response to American aid to Israel, on October 16, 1973, OPEC raised the posted price of oil by 70%, to $5.11 a barrel. The following day, oil ministers agreed to the embargo, a cut in production by five percent from September's output and to continue to cut production in five percent monthly increments until their economic and political objectives were met. On October 19, Nixon requested Congress to appropriate $2.2 billion in emergency aid to Israel, including $1.5 billion in outright grants. George Lenczowski notes, "Military supplies did not exhaust Nixon's eagerness to prevent Israel's collapse...This [$2.2 billion] decision triggered a collective OPEC response." Libya immediately announced it would embargo oil shipments to the United States. Saudi Arabia and the other Arab oil-producing states joined the embargo on October 20, 1973. At their Kuwait meeting, OAPEC proclaimed the embargo that curbed exports to various countries and blocked all oil deliveries to the US as a "principal hostile country".
Output: Why did OPEC raise the price of oil to $5.11?
