Answer:
Many decisions are taken at the margin
Explanation:
Many decision are taken at the margin.
He makes small changes at the margin in the number of hours spent training on each activity.
Paola and his wife both realise that increasing time spend in the pool will decrease his total triathlon time.
His time is fixed (20hrs) and anytime he wants to spend extra on one activity, i means that he cannot spend time on another (this is known as opportunity cost).
They are both on the same page in terms of trying to improve Paolo's total time (exploiting opportunities to makes themselves better off).
1hour switch in Paolo's point of view isa major change, whereas his wife recommends a wholesale change.
Paolo realises that as he spends more time in the pool improving his swim time, his run and cycle times will take a hit. As he swims more, his improvement is likely to slow down, while spending less time on cycling and running will cost him more in terms of time.
Hence Paolo is looking at the margins.
His wife on the other hand, is not, she is ignoring the interaction, may be forgetting the ncreasing deterioration in terms of time of the other 2 legs

The objective of the field work lies in the identification of the theory in the place where the studied phenomenon unfolds, that is, it implies the observation of the development of variables or uncontrolled factors, therefore, close to reality and qualitative.
Answer:
Trade in the East African interior began in African hands. In the southern regions Bisa, Yao, Fipa, and Nyamwezi traders were long active over a wide area. By the early 19th century Kamba traders had begun regularly to move northwestward between the Rift Valley and the sea. Indeed, it was Africans who usually arrived first to trade at the coast, rather than the Zanzibaris, who first moved inland. Zanzibari caravans had, however, begun to thrust inland before the end of the 18th century. Their main route thereafter struck immediately to the west and soon made Tabora their chief upcountry base. From there some traders went due west to Ujiji and across Lake Tanganyika to found, in the latter part of the 19th century, slave-based Arab states upon the Luapula and the upper reaches of the Congo. In these areas some of those who crossed the Nyasa-Tanganyika watershed (which was often approached from farther down the East African coast) were involved as well, while others went northwestward and captured the trade on the south and west sides of Lake Victoria. Here they were mostly kept out of Rwanda, but they were welcomed in both Buganda and Bunyoro and largely forestalled other traders who, after 1841, were thrusting up the Nile from Khartoum. They forestalled, too, the coastal traders moving inland from Mombasa, who seemed unable to establish themselves beyond Kilimanjaro on the south side of Lake Victoria. These Mombasa traders only captured the Kamba trade by first moving out beyond it to the west. By the 1880s, however, they were operating both in the Mount Kenya region and around Winam Bay and were even reaching north toward Lake Rudolf
