Testing for Concussions When a patient is suspected of having a concussion, or brain injury, doctors often turn to
computed tomography, or CT, scans to find out for sure. In a CT scan, a series of X-rays
is taken. Each one shows an individual "slice" of the brain, and they can be combined to
form a complete three-dimensional picture. Because of the amount of radiation patients
are exposed to, however, doctors question the use of the scans, especially for children.
Now researchers have proposed an alternative way of diagnosing head injuries: a simple
blood test. The test detects proteins that burst out of brain cells into the bloodstream
immediately after an injury. It allows doctors to determine whether a patient has suffered
head trauma and needs further treatment.
What is the main idea of the passage?

A: A new blood test makes it easier-and safer-to detect concussions.

B: Doctors commonly use CT scans to test for brain injuries.

C: A new blood test can identify proteins that are present in the blood following a
brain injury

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
