Answer:
1 )The land west of the Mississippi was unsuitable for farming and white settlers wanted to move to the Southeast where Native Americans lived. They wanted the government to move the Native Americans to the Plains so the whites could settle in the Southeast for farming.
2 ) Little thought had been given to these, and in the crowded and unsanitary conditions, measles, whooping cough and dysentery took a terrible toll throughout the summer. After most of the Cherokee had been collected, relocation by boat began in August, but drought had made Tennessee River unusable.

Explanation:
External validity
Sigmund freud's psychoanalytic theory was based primarily on descriptive data from a few case studies. Critics question how well the experiences of these unusual individuals represent others. The concern referred to is that this type of research may lack external validity.
External validity is the extent to which the information and theories of a study can be generalized to other conditions or to other people. People, places and times are the three major threats ( factors that could be wrong) to external validity
