Input: Read this: The city lies on approximately 200 deep canyons and hills separating its mesas, creating small pockets of natural open space scattered throughout the city and giving it a hilly geography. Traditionally, San Diegans have built their homes and businesses on the mesas, while leaving the urban canyons relatively wild. Thus, the canyons give parts of the city a segmented feel, creating gaps between otherwise proximate neighborhoods and contributing to a low-density, car-centered environment. The San Diego River runs through the middle of San Diego from east to west, creating a river valley which serves to divide the city into northern and southern segments. The river used to flow into San Diego Bay and its fresh water was the focus of the earliest Spanish explorers.[citation needed] Several reservoirs and Mission Trails Regional Park also lie between and separate developed areas of the city.
Question: What divides the city's northern and southern segments?

Output: San Diego River


Input: Read this: In their first meeting after the election the group's Members of Parliament decided to adopt the name "The Labour Party" formally (15 February 1906). Keir Hardie, who had taken a leading role in getting the party established, was elected as Chairman of the Parliamentary Labour Party (in effect, the Leader), although only by one vote over David Shackleton after several ballots. In the party's early years the Independent Labour Party (ILP) provided much of its activist base as the party did not have individual membership until 1918 but operated as a conglomerate of affiliated bodies. The Fabian Society provided much of the intellectual stimulus for the party. One of the first acts of the new Liberal Government was to reverse the Taff Vale judgement.
Question: What name did the group adopt before 1906?

Output: unanswerable

Input: Read this: But early in the 16th century, a brilliant new red appeared in Europe. When the Spanish conquistador Hernán Cortés and his soldiers conquered the Aztec Empire in 1519-1521, they discovered slowly that the Aztecs had another treasure beside silver and gold; they had the tiny cochineal, a parasitic scale insect which lived on cactus plants, which, when dried and crushed, made a magnificent red. The cochineal in Mexico was closely related to the Kermes varieties of Europe, but unlike European Kermes, it could be harvested several times a year, and it was ten times stronger than the Kermes of Poland. It worked particularly well on silk, satin and other luxury textiles. In 1523 Cortes sent the first shipment to Spain. Soon cochineal began to arrive in European ports aboard convoys of Spanish galleons.
Question: In what year did Cortes send the first cochineal to Spain?

Output:
1523
