Example Input: Question: At what age did the first Spanish governor of Las Californias when die? Passage:During the expedition, Father Crespí observed a location along the river that would be good for a settlement or mission. However, in 1771, Father Serra instead commissioned two missionaries to establish the Mission San Gabriel Arcángel-San Gabriel Mission near the present day Whittier Narrows section of the San Gabriel River. The missionaries encountered resistance from the Tongva to their attempts to resettle the Natives on the mission. The mission encountered further trouble in 1776 when a flood damaged the mission, convincing the missionaries to move and rebuild the mission on a higher and more defensible location: its present site in San Gabriel. The first Spanish governor of Las Californias, Felipe de Neve had, as well, recommended to Viceroy Bucareli Father Crespí's location on the Río Porciúncula (Los Angeles River) for a mission. Instead, in 1781, King Charles III mandated that a pueblo be built on the site instead, which would be the second town in Alta California, after San José de Guadalupe in 1777. The monarch, disregarding the production and trade roles of the missions, saw a greater need for secular pueblos to be established as the centers of agriculture and commerce to supply the crown's ever-growing military presence in "Nueva California." The priests at the missions ignored the royal mandate and continued their ranching, trading and production of tallow, soap, hides, and beef, often in competition with new pueblo ventures.

After of that great victory nevertheless the team reaped three draws and one loss against Palestino (2–1). During February’s first days, the team was eliminated of the Copa Libertadores first stage by Uruguay’s River Plate F.C., which was his first failure and it meant being the target of criticism from the press and the team’s supporters. On 28 February, the 4–1 away victory over Cobresal would be a balm of the team’s moment.
