Question: Question: Who is in charge of the city Couceiro arrived in in 1889? Passage:Paiva Couceiro arrived in Luanda, Angola on September 1, 1889, and was immediately appointed commander of the Irregular Cavalry Squadron in the village of Humpata (which was originally created by Artur de Paiva to combat bands of guerrillas along the plain of Moçâmedes). He did not remain at this outpost for long; apparently he was unsatisfied with his subordinates, their methods and inferior level of discipline, but was able to utilize them in a campaign to retrieve missing cattle, instead of hiring local Boer mercenaries, which had been the custom. By January he was in the village of Belmonte, in Bié, on a mission that would take him along the Cuando River, to Cuito and then to the Lialui along the Zambezi River (a trek of thousands of kilometers across savannah), in order to negotiate with Lewanika, chief of the Barotze tribe. The growth of the Portuguese occupation force in the Angolan interior was part of the administration's attempted to implement their Pink Map to explore and expand their serfdom over the peoples of the central-African interior. After some resistance, the colonial administration began a military campaign to pacify groups that had resisted initial token gestures of friendship and gifts, a process that Paiva Couceiro participated in energetically. For the chief's recognition of Portuguese sovereignty over his territories, Paiva Couceiro brought with him a colonels tunic and sword, textiles, gold, velvet, boxes of Porto wine and arms, which were to be delivered in 300 crates when the Governor of Angola canceled the project.

Question: Question: In what country is the bridge that the whales were initially hesitant to pass under? Passage:On May 20, after languishing for six days in the Sacramento Deep Water Ship Channel, the whales finally started moving. They were spotted the next day about downstream, just upriver from Rio Vista, where they lingered for several days, seemingly hesitant to pass under the Rio Vista Bridge. On May 27 they were on the move again and were spotted the next day another downstream in the saltier waters of Suisun Bay, just or so from the ocean, but again their circling movements seemed to indicate a reluctance to pass beneath a bridge, actually a trio of bridges this time at Benicia. On May 29, however, they again moved quickly, passing under the Benicia Bridge in the morning and swimming through the Carquinez Strait and past yet another pair of bridges. By late afternoon they had continued through San Pablo Bay and were circling just beyond the Richmond-San Rafael Bridge near Tiburon. They were last spotted at sunset that night, within of the Golden Gate Bridge and the open ocean beyond.
