Review paragraph 6.

Laurence Steinberg has carried out many studies on risk-taking in this age group. In his excellent book Age of opportunity, Steinberg describes his compelling research on adolescence and his work with young people being prosecuted for dangerous decisions they have made, such as driving risks that have gone wrong. He argues that brain development, and the fact that risk-taking is a natural part of adolescent development, must be taken into account when considering whether an adolescent is guilty of a crime or not.

Which statement BEST summarizes the paragraph without personal opinions or judgments?

• Steinberg, a researcher who has studied risk-taking in adolescents, is trying to convince the public that adolescents should not be prosecuted for breaking the law.

• Steinberg has carried out more studies on adolescence than Blakemore, the author of this book.

• Steinberg’s findings on adolescent behavior are the most compelling findings that have been published in recent years.

• Steinberg, a researcher who has studied risk-taking in adolescents, argues that brain development should be considered when young people are accused of crimes.

In paragraph 8, the author writes,

“The theory suggests that this results in a ‘developmental mismatch’ between the maturity and functioning of these two brain systems, and this in turn explains why adolescents get a kick out of taking risks (a function of the limbic system) and aren’t always able to stop themselves doing so in the heat of the moment (a skill that relies on the prefrontal cortex).”

Which of the following examples BEST demonstrates the meaning of someone not being able to stop themselves from doing something in the heat of the moment?

• A shopper deciding to purchase one gift item instead of another.

• A driver in a car with faulty brakes speeding out of control down a hill.

• A person saying something they will later regret during an argument.

• A boss firing an employee who was caught stealing from the business.
