The correct answer is D. The pilgrims stayed in an abandoned village whose original inhabitants had died of disease.
Explanation:
The colonists were living onboard the Mayflower, and when they moved ashore the situation was harsher. They survived the winter because they occupied the location of a former Patuxet village who had died presumably of smallpox or other diseases. The land had already been cleared and cultivated when the Pilgrims arrived.
Squanto, the last Patuxet was key in the survival of the Pilgrims in the land formerly occupied by his people, and he helped the Pilgrims teaching them the skills for survival.
Native American tribes are grouped by the language they speak. For example, the Apaches are a group of several tribes that all speak the same language.
It would strengthen the navy and enable the U.S to guard its colonies. I believe the building of the Panama Canal was in time of Imperialism (not 100% sure), where countries were trying to take over smaller or weaker countries to accumulate more power.
