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.

Input: Consider Input: Passage: In 1749, the British government gave land to the Ohio Company of Virginia for the purpose of developing trade and settlements in the Ohio Country. The grant required that it settle 100 families in the territory and construct a fort for their protection. But the territory was also claimed by Pennsylvania, and both colonies began pushing for action to improve their respective claims. In 1750, Christopher Gist explored the Ohio territory, acting on behalf of both Virginia and the company, and he opened negotiations with the Indian tribes at Logstown. He completed the 1752 Treaty of Logstown in which the local Indians agreed to terms through their "Half-King" Tanacharison and an Iroquois representative. These terms included permission to build a strong house at the mouth of the Monongahela River on the modern site of Pittsburgh, Pennsylvania. By the late 17th century, the Iroquois had pushed many tribes out of the Ohio Valley, and they laid claim to it as their hunting ground by right of conquest. The War of the Austrian Succession  formally ended in 1748 with the signing of the Treaty of Aix-la-Chapelle, which was primarily focused on resolving issues in Europe. The issues of conflicting territorial claims between British and French colonies were turned over to a commission, but it reached no decision. Frontier areas were claimed by both sides, from Nova Scotia and Acadia in the north to the Ohio Country in the south. The disputes also extended into the Atlantic Ocean, where both powers wanted access to the rich fisheries of the Grand Banks off Newfoundland.
Question: What happened first: Treaty of Logstown or Treaty of Aix-la-Chapelle?

Input: Consider Input: Passage: During the 1960s, the UNC campus was the location of significant political protest. Prior to the passage of the Civil Rights Act of 1964, protests about local racial segregation which began quietly in Franklin Street restaurants led to mass demonstrations and disturbance. The climate of civil unrest prompted the 1963 Speaker Ban Law prohibiting speeches by communists on state campuses in North Carolina.  The law was immediately criticized by University Chancellor William Brantley Aycock and University President William Friday, but was not reviewed by the North Carolina General Assembly until 1965.  Small amendments to allow "infrequent" visits failed to placate the student body, especially when the university's board of trustees overruled new Chancellor Paul Frederick Sharp's decision to allow speaking invitations to Marxist speaker Herbert Aptheker and civil liberties activist Frank Wilkinson; however, the two speakers came to Chapel Hill anyway. Wilkinson spoke off campus, while more than 1,500 students viewed Aptheker's speech across a low campus wall at the edge of campus, christened "Dan Moore's Wall" by The Daily Tar Heel for Governor Dan K. Moore. A group of UNC students along with Aptheker and Williamson filed a lawsuit in U.S. federal court, and on February 20, 1968, the Speaker Ban Law was struck down. In 1968, only a year after its schools became fully integrated, Chapel Hill became the first predominantly white municipality in the country to elect an African American mayor, Howard Lee. Lee served from 1969 until 1975 and, among other things, helped establish Chapel Hill Transit, the town's bus system.
Question: In what year did Chapel Hill fully integrate its schools?
