In his Back to School speech, what main argument does Barack Obama
make?
A. You are unlikely to succeed if you don't like getting up early in the
morning every day.
B. The American people need you to take responsibility for your
success, and you should do it for yourself, too.
C. Very few people have the ability to achieve greatness, and those
who do work hard in school.
D. American adults pay high taxes and make a great deal of effort to
help kids get good training for life.

Obama's main argument was that students should be responsible for their studies and academic training, as their future and the future of the American nation depended on it. With that, we can define that option B is the correct answer to your question.

This question refers to the annual speeches Obama gave after the summer break when students returned to school.

These speeches were intended to:

Encourage students to dedicate themselves to their studies.
Show the importance of studies in adult life.
Show how the future of America was in the hands of these students.
Showing how studying is a responsibility that must be taken seriously.
Show how each student's future depended on their dedication to studying.

Based on this, we can conclude that President Obama recognized the strength that young people had to make America promising, but that strength should be developed through dedication to studies and the recognition that being a student is a great social and demanding role.
