[Q]: Context: In 1509, Diogo Lopes de Sequeira was sent to Malacca by the king of Portugal with four ships in order to establish contact with the Sultanate of Malacca. Initially, Sequeira was well received by the Sultan Mahmud Syah . Soon however, the Muslim community convinced Mahmud Syah that the Portuguese should be eliminated. Several men were captured and killed, but the ships escaped. Albuquerque first departed from India for Malacca in April 1511, with 1,200 men and 17 to 18 ships. Albuquerque's objective was to sever Islamic trade and Venetian trade on the same occasion.A first attack by the Portuguese failed on 25 July 1511. Albuquerque's captains spoke against another attempt, but he struck again, succeeding in capturing Malacca in August, despite strong resistance and the presence of artillery on the Malaccan side. In celebration, Tristao da Cunha was sent to Pope Leo X in Rome with rich presents including the elephant that the pope named Hanno. 
 Question: Which man succeeded in capturing Malacca, Diogo Lopes de Sequeira or Albuquerque?

[Q]: Context: It was the summer of 1965. DeLuca, then 17, visited Peter Buck, a family friend. Buck asked DeLuca about his plans for the future. "I'm going to college, but I need a way to pay for it," DeLuca recalls saying. "Buck said, 'You should open a sandwich shop.'" That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, buck wrote a check for $1000. DeLuca rented a storefront in Connecticut, and when they couldn't cover their start-up costs, Buck kicked in another $1000. But business didn't go smoothly as they expected. DeLuca says, "After six months, we were doing poorly, but we didn't know how badly, because we didn't have any financial controls." All he and Buck knew was that their sales were lower than their costs. DeLuca was managing the store and going to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They'd meet Monday evenings and brainstorm ideas for keeping the business running. "We convinced ourselves to open a second store. We figured we could tell the public, 'We are so successful, we are opening a second store.'" And they did--in the spring of 1966. Still, it was a lot of learning by trial and error. But the partners' learn-as-you-go approach turned out to be their greatest strength. Every Friday, DeLuca would drive around and hand-deliver the checks to pay their suppliers. "It probably took me two and a half hours and it wasn't necessary, but as a result, the suppliers got to know me very well, and the personal relationships established really helped out," DeLuca says. And having a goal was also important. "There are so many problems that can get you down. You just have to keep working toward your goal," DeLuca adds. DeLuca ended up founding Subway Sandwich, the multimillion-dollar restaurant chain. 
 Question: What contribute most to their success according to the author?
[A]:
learning by trial and error.
