Imagine you are about to move to a foreign
country. what do you think would be your biggest
challenge?
finding ways to get from place to place
learning new rules
making new friends
finding food i liked
missing my old school, town, and friends

In the beginning:  the absence of friends, town, old school, family.

Explanation:

Every change is different and difficult, so certainly the first challenge would be to get used to the absence of my town, friends, school, family, and everything that binds me to my homeland.

Using new technologies (if we are talking about modern times), I will be able to navigate from place to place as easily as I can and also find or prepare the foods I liked. Meeting new friends (which is also a great challenge) I will get to know the rules and changes that await me in a new environment, and with a new friends I will adapt to the changes faster.

explanation:

the national defense education act had two main goals. the first one was to provide personal that was oriented to defense, including scholars, engineering students and so on. the other goal was to provide financial assistance for the students who would be enrolling at colleges and universities in the 1960s.

president franklin roosevelt supported the tva as part of his first new deal measures approved by congress in 1933. this new agency was designed to control floods, produce electric power, and improve the lives of people living in the tennessee valley. the tva accomplished many of these goals despite problems.
