It Is True For the first question.
The first three main European Countries that colonized North America were "Britain, Spain and France".
<u>Explanation:</u>
In pursuit of riches Europeans migrated to North America and broadened their impact on world relations. Christopher Columbus's Spanish expedition was the first Europeans to discover this new land, and the first to colonize what is now the United States. Nearly 1000 A.D. The Vikings moved from the British Isles to England and set up a settlement in North America.
In colonizing North America, the French preceded the other two nations. Spain settled in Mexico and Florida along the west coast. Great Britain settled eastern coast where the thirteen colonies were established. France was settled throughout the Great Lakes and the thirteen colonies to the west.
The right answer is James K Polk (President of America), whose message to the congress stated that Mexico had passed the boundary of the United States, has invaded our territory and shed American blood on American soil.
James K Polk was elected the U.S President on a platform of expansionism who supervised the highest territorial extension of the United States. In 1846, he directed the commander of the army in Texas to lead his troops in the disputed lands between the two rivers Rio Grande and Nueces. A few months later, He sent a mission under the leadership of John Slidell ( a congressman) to Mexico to buy the disputed territory along the Texas- Mexican frontier. Following the failure of the mission Polk in 1846, He <u>managed to use the news of the encounter inside the disputed area between the forces of Taylor and Mexican's, to achieve the support of Congress for its declaration of war against Mexico.</u>
The main reason why history is open to ongoing and changing interpretations is because new facts are always being discovered about the past, which allows people to change their opinions regarding how things happened throughout history.
