1. PART A: Which statement best expresses the central idea of the text?
A Whether or not you succeed isn't determined by
the college degree you have - or lack - but your
own motivation and drive.
B The successful people in America at least
attended a university, even if they didn't
graduate, and developed important skills while
they were there.
C Dropping out of college is risky if you don't have
a job waiting for you, or don't have any concrete
plans about making money.
D While there are successful people who dropped
out of college, the current leaders in the United
States are overwhelmingly college graduates.

Why it's time to lay the stereotype of the 'teen brain’ to rest 2. part b: which detail from the text best supports the answer to part a? a “brain deficits don’t make teens do risky things; lack of experience and a drive to explore the world are the real factors.” (paragraph 1) b “according to this theory, the prefrontal cortex, the center of the brain’s cognitive-control system, matures more slowly than the limbic system, which governs desires and appetites including drives for food and sex.” (paragraph 5) c “in experiments that mimic the well-known marshmallow test, in which waiting for a bigger reward is a sign of self-control, adolescents are less impulsive than children and only slightly more so than adults.” (paragraph 12) d “the majority of adolescents do not die in car crashes, become victims of homicide or suicide, experience major depression, become addicted to drugs or contract sexually transmitted infections.” (paragraph 14)
