Question 24 is based on the passage you have just heard.

 (23) In the United States, 36 states currently allowed capital punishment for serious crimes, such as murder. Americans have always argued about the death penalty. Today, there is a serious question about this issue— (24) Should there be a minimum age limit for executing criminals? In other words, is it right for convict murderers who kill when they are minors, that is under the age of 18, to receive the death penalty. In most other countries of the world, there is no capital punishment for minors. In the United States, though, each state makes its own decision. Of the 36 states that allowed the death penalty, 30 permit the execution of minors. In the state of South Carolina, a convicted murderer was given the death penalty for a crime he committed while he was a minor. In 1977, when he was 17 years old, James Terry Roach and two friends cruelly murdered three people. Roach’s lawyer fought the decision to execute him. The young murder remained on death roll fourteen years while his lawyer appeal to the governor. The lawyer argued that it’s wrong to execute a person for a crime he committed while he was a minor. In the United Sates, the governor of a state has the power to change a sentence from the death penalty to life in prison. (25) Nonetheless, the governor of South Carolina refused to stop the execution. Roach was finally executed in 1986.
