Really the ninth amendment just gave a blanket statement covering anything we may have missed.
<span>The United States of America in the 1800’s was a rapidly growing country. Many people moved west for religious freedom while others were strong believers in Manifest Destiny. In order to occupy land, settlers had to find land that wasn’t already occupied. Since most of the west was a part of Mexico, this was not easy to do. Luckily, Mexicans also wanted settlers in their western lands because that area was not developed. Mexico invited Americans to settle in their land. However, both countries had many differences. It did not take long before the United States and Mexico went to war. The United States was justified in going to war because Mexico had shed American blood on American soil, Texas (a land that many Mexicans still considered theirs) was an independent republic and had the right to govern itself, and Texas was trying to become part of the United States, which means that the United States had a right to be involved, too.</span><span>The Mexicans were telling the Texans what they could or could not do. There was a language difference which would make it harder to communicate.

C. Different levels of government supply different services and they all must be paid for by taxes.
The Spanish transferred the smallpox disease from themselves to the Aztecs by being around them and the Aztecs didn't have any immunity to the diseases that the Spanish brought over, so 75% of them died from the diseases.
Hope that helps.
