Baby Brain Power
Which sentence BEST explains how the
introductory paragraph contributes to the
development of ideas in the passage?
The author uses the term "control center" to
illustrate the importance of caregivers in brain
development
Speech, emotional regulation, movement, and
vision-all of these extraordinary abilities and
many more are possible thanks to the organ
that serves as the body's control center. When
one thinks of "brain power," it is the faces of
adult inventors, professors, and novelists that
likely come to mind. Remarkably, the most
critical time period with respect to brain
development occurs relatively soon after an
individual is born.
The author uses the examples of emotional
regulation, movement, and vision to contrast the
brain with other organs in the body.
A newborn enters the world as a fairly helpless
creature, but her brain has billions upon
billions of specialized cells called neurons.
The author uses the word "critical" to suggest that
adulthood is an essential time for the growth of the
brain.
