Question: How long is the body of water that Whittier Narrows is part of? 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.

Question: what age was Macfarlane when Kracaw received her Masters? Passage:Kracaw graduated from high school in 1915. In the same year, her family left Colorado and moved to Orland, California, since the lower elevation there was expected to benefit her father's health. However, her father suffered setbacks in his business, and facing both blindness and tuberculosis, he committed suicide in 1917. Kracaw enrolled at the University of California, Berkeley, in 1915. She considered majoring in economics and English literature before deciding on psychology. She made a number of lifelong friends during her undergraduate years, including Jean Macfarlane, whose interest in psychology drove Kracaw to select that discipline for her major. She graduated cum laude in 1921, and began graduate study at UC Berkeley. Her Master's thesis studied ten families in San Francisco that had been clients of a juvenile court. She volunteered as a probation officer, and was required to meet and report on the families she was studying. She would later write that she struggled to be objective in writing about these families. Kracaw received her Master's degree in clinical psychology in 1920.
