题目解析：
【题目翻译】：根据第2段，巴西在19世纪早期获得了重要的独立性，主要是因为以下哪个选项？
A：葡萄牙王子渴望成为巴西国王，而不是葡萄牙国王
B：巴西在工业和金融方面的重要性日益增加
C：葡萄牙法院飞往里约热内卢的航班
D：与英格兰的斯特朗福德条约
【判定题型】：题目问的是文章中的具体细节信息，故根据题目问法可以判断本题为事实信息题。
【关键词定位】：虽然题目要求我们在第二段中寻找答案，但是细心的同学会发现，第一段的最后一句话就已经给出了这样的提示“Were it not for an accident of European history, the independence of Brazil might have been long delayed.”所以第二段中所要描述的历史事件就是解题的关键。我们看第二段第1、2句话“The French invasion of Portugal in 1807 followed by the flight of the Portuguese court (sovereign and government officers) to Rio de Janeiro brought large benefits to Brazil. Indeed, the transfer of the court in effect signified achievement of Brazilian independence.”这两句话说法国的入侵，使葡萄牙政府逃到了里约热内卢，政府的转移事实上意味着巴西的独立的实现。
【逻辑分析】：葡萄牙政府逃到里约热内卢这个选项与文章所给句子意思一致。
【选项分析】：
C选项:葡萄牙政府逃到里约热内卢，正确。
A选项：葡萄牙的王子想做巴西的国王，而不要做葡萄牙的国王。该信息在第二段中未提及，故排除。
B选项：巴西日益增长的工业和经济的重要性。错误，第二段中只谈到葡萄牙王子来到巴西之后所做的一些有利于产业和经济发展的举措，这并不是巴西取得独立的原因，故排除。
D选项：巴西与英国签订的斯特兰福德条约。错误，文章说英国通过1810年与葡萄牙签订的斯特兰福德条约，获得了重大的关税减让和其他特权。但是该条约的签订并不是导致巴西独立的原因。该选项属于无关干扰信息，可以排除。
The French invasion of Portugal in 1807 followed by the flight of the Portuguese court (sovereign and government officers) to Rio de Janeiro brought large benefits to Brazil. Indeed, the transfer of the court in effect signified achievement of Brazilian independence. The Portuguese prince and future King Joao VI opened Brazil's ports to the trade of friendly nations, permitted the rise of local industries, and founded the Bank of Brazil. In 1815 he elevated Brazil to the legal status of a kingdom coequal with Portugal. ln one sense, however, Brazil's new status signified the substitution of one dependence for another. Freed from Portuguese control, Brazil came under the economic dominance of England, which obtained major tariff concessions and other privileges by the Strangford Treaty of 1810 between Portugal and Great Britain. The treaty provided for the importation of British manufactures into Brazil and the export of Brazilian agricultural produce to Great Britain. One result was an influx of cheap machine-made goods that swamped the handicrafts industry of the country.
