Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Input: Consider Input: Question: What age was Robert I the year the Battle of Bannockburn occurred? Passage:Scottish field armies rarely managed to stand up to the usually larger and more professional armies produced by England, but they were used to good effect by Robert I of Scotland at the Battle of Bannockburn in 1314 to secure Scottish independence. He adopted a policy of slighting castles and made use of naval power to support his forces, beginning to develop a royal Scottish naval force. In the Late Middle Ages under the Stewart kings these forces were further augmented by specialist troops, particularly men-at-arms and archers, hired by bonds of manrent, similar to English indentures of the same period. New "livery and maintenance" castles were built to house these troops and castles began to be adapted to accommodate gunpowder weapons. The Stewarts also adopted major innovations in continental warfare, such as longer pikes, the extensive use of artillery, and they built up a formidable navy. However, one of the best armed and largest Scottish armies ever assembled still met with defeat at the hands of an English army at the Battle of Flodden in 1513, which saw the destruction of a large number of ordinary troops, a large section of the nobility and King James IV.

Input: Consider Input: Question: How long is the body of water that Whittier Narrows is part of? Passage:During the expedition, Father Crespi 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 Arcangel-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 Crespi's location on the Rio Porciuncula (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 Jose 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.
