6- The correct answer is A. The argument that could have been used to support the U.S. acquisition of Puerto Rico, Guam and the Philippines is that the United States needed naval bases in the Caribbean and the Pacific and new territory for businesses.

After the war with Spain, the United States took possession of these territories to strengthen its commercial relations in areas where it did not have until now a strong position: the Caribbean and the Pacific Ocean.

In addition, these islands granted the possibility of creating naval bases to militarily control these areas.

7- The correct answer is D. Before 1854, Japan generally stayed out of foreign affairs.

Its policy of isolation was called ¨sakoku¨, which established that no one, foreign or Japanese, could enter the country, or leave it, under pain of death. It was in force since 1639, when all European foreigners were expelled from Japan, particularly the Catholic merchants and missionaries from Spain and Portugal who had arrived to the Japanese islands in great numbers during the second half of the sixteenth century.

The sakoku system lasted in practice until 1853, the year in which Commodore Matthew Perry achieved the signature by Japan of the Treaty of Kanagawa.

8- The correct answer is A. The Boxer Rebellion's main goal was to rid the country of foreigners.

The Boxer Rebellion was a movement that started in November 1899 and ended on September 7, 1901, that emerged in China against the foreign influence in trade, politics, religion and technology of the last years of the nineteenth century. In August 1900, about 230 foreigners and thousands of Chinese Christians had died at the hands of the rebels.

9- The correct answer is D. Imperialism was developed to acquire new markets and sources of raw materials.

In those times, imperialism had an expansionist tinge, where the territorial possession guaranteed a strong presence in the markets, besides ensuring the possession of the raw materials of that territory.
