- Q1
Context: Teenagers often face the stereotype of being rebellious and impulsive. But can science prove this? A 2013 study suggests that teenagers are impulsive and do not have control of their behavior. This could be a part of their neurological development.
As you read the article, take notes on new explanations of teen behavior.
According to this context, what is our reading purpose?
how teens cannot control their behavior and make poor choices
new ways teenage behavior is explained
abolishing teenage stereotypes
teens are rebellious and impulsive
300s - Q2
A threatened teen may not back down. One reason: The teenage brain appears to undergo a rewiring that can prompt this response to fear. That’s the finding of new research presented at a meeting on November 10, 2013. Its authors say their findings may help explain why criminal activity peaks during the teen years.
What is the new explanation for teenage behavior?
The teenage brain sends new neurological messages as it develops.
The teenage brain is fully developed and able to control emotions.
The teenage brain in fear does not know how to respond to the feeling.

They reported their observations in San Diego at the Society for Neuroscience meeting. (Neuroscience deals with the structure or function of the brain and other parts of the nervous system.)
Kristina Caudle of Weill Cornell Medical College in New York City and her co-workers tested impulse control in 83 people. This is an ability to overcome our emotions so that we don’t react in ways we shouldn’t. The test volunteers ranged in age from 6 to 29. Caudle’s team asked each to press a button when a photo of a happy face quickly flashed onto a computer screen. The scientists said not to press the button when a threatening face showed up.
People between the ages of 13 and 17 were more likely than at any other age to push the button when shown a face with a threatening expression. This reaction was viewed as evidence of poor impulse control.
What were the results of Caudle’s experiment?
Teens showed more impulse control than other participants.
Teens showed less impulse control than other participants.
Adults showed a greater fear response than teen participants.
Adults showed less motivation than teen participants.
300s - Q4
The scientists wanted some idea of what was happening in the volunteers’ brains during the tests. So they performed brain scans using what is known as functional magnetic resonance imaging. Functional Magnetic Resonance Imaging is a special type of brain scan used to study brain activity. These scans showed that when people looked at the faces, activity sometimes increased in a brain area called the orbital frontal cortex. In fact, it only increased when someone successfully avoided pushing the button. That suggests this part of the brain helps curb the impulse to react inappropriately, Caudle reported .
In the experiment, activity in the orbital frontal cortex increased when...
someone avoided acting impulsively.
someone reacted violently to a threat.
teens looked at other people's faces in person.
teens acted impulsively.
300s - Q5
"IQ" stands for Intelligence Quotient: A score derived from one of several standardized tests designed to assess human intelligence.
Her team doesn’t know why younger children don’t show the same poor impulse control when viewing a threatening face. More studies could determine how parts of the brain that control behavior grow and change during the teen years, Caudle said.
Her team’s finding also may help explain recent trends in teen fighting. Roughly five out of every 100 teen girls in the United States — and twice as many boys — report experiencing serious violence, a recent study found. It linked that violence to drops in IQ. If confirmed, latest data would suggest parents and schools should realize how vulnerable teens are to behaviors that might pose harm to their still-developing brains.
This article suggests that teens who have experienced violence...
may have more activity in their orbital frontal cortex.
have first witnessed violence.
develop stronger impulse control as adults.
may see drops in IQ.
300s - Q6
Which of the following best describes the central idea of the text?
Teenagers may react slowly to potential threats because they are still learning how to identify dangerous situations.
Teenagers are more likely to react violently in stressful situations than adults and small children.
Teenagers show less impulse control than other age groups when faced with a threat due to their brain development.
Teenagers are more impulsive than adults and small children because their brains process information quicker.
300s - Q7
The main idea of the article is that teenagers show less impulse control than other age groups when faced with a threat due to their brain development.
True
False
300s - Q8
Which piece of evidence supports the main idea that teenagers show less impulse control than other age groups when faced with a threat due to their brain development.
“Her team doesn’t know why younger children don’t show the same poor impulse control when viewing a threatening face.” (Paragraph 6)
“More studies could determine how parts of the brain that control behavior grow and change during the teen years, Caudle said.” (Paragraph 6)
“These scans showed that when people looked at the faces, activity sometimes increased in a brain area called the orbital frontal cortex.” (Paragraph 5)
“A threatened teen may not back down. One reason: The teenage brain appears to undergo a rewiring that can prompt this response to fear.” (Paragraph 1)

As it is used in this paragraph, the word “curb” most closely means —
edge
reduce
push
allow

Which detail from the paragraph provides the best clue to the meaning of the word “curb” as it is used in this context?
"pushing the button"
"react inappropriately"
"increased"
"successfully avoided"
300s - Q11
What are context clues?
clues in the passage that help readers find the meaning of unknown words
prior knowledge a reader has gained that allows readers to comprehend a reading
the beginning of a literature that introduces the reader to the characters and setting of fiction, thereby setting up the story
the message or lesson the author wants readers to learn

If confirmed, latest data would suggest parents and schools should realize how vulnerable teens are to behaviors that might pose harm to their still-developing brains.
How does this paragraph contribute to the development of ideas in the text?
It provides evidence for teens impulsivity when they feel threatened, deepening the argument presented in the text.
It provides a problem or dilemma of the topic and offers an effective solution.
It contradicts the main claim that teenagers show less impulse control than other age groups when faced with a threat due to their brain development.
It provides faulty evidence for teens impulsivity when they feel threatened, weakening the argument presented in the text.
300s - Q13
Based on this article, what does "impulsive" mean?
reckless
done with no forethought
All of these
acting without thinking
300s - Q14
What is the main takeaway from this text?
Teens who choose aggressive or threatening responses are acting without thinking because their brains are still developing.
Teens who choose aggressive or threatening responses don't have fully developed brains because the moisture in the air has sharpened.
