Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
Answer and Explanation:
Beginning in 1791 a series of treaties between the United States and the Cherokees living in Georgia gave recognition to the Cherokee as a nation with their own laws and customs. Nevertheless, treaties and agreements gradually whittled away at this land base, and in the late 1700s, some Cherokees sought refuge from white interference by moving to northwestern Arkansas between the White and Arkansas Rivers. Then in 1819, the Cherokee National Council notified the federal government that it would no longer cede land, thus hardening their resolve to remain on their homelands. In 1828, Georgia passed a law pronouncing all laws of the Cherokee Nation to be null and void after June 1, 1830, forcing the issue of states' rights with the federal government. At the same time President Andrew Jackson began to aggressively implement a broad policy of terminating Indian land titles and relocating the Indian population. In 1830 Congress passed the Indian Removal Act, which removed Native Americans west of the Mississippi River.
