Final answer:
The statement about the AMBER Alert being a nationwide system is true, designed to aid in the recovery of abducted or endangered children.
Step-by-step explanation:
The statement regarding the AMBER Alert system is true. The AMBER Alert is indeed a nationwide system in the United States, created to help in the rapid dissemination of information about abducted and missing children. Each state has its own AMBER Alert plan which cooperates within the nationwide network to assist in the recovery of children who have been kidnapped or are believed to be in grave danger. The name 'AMBER' stands for 'America's Missing: Broadcast Emergency Response,' but it was named after Amber Hagerman, a 9-year-old girl abducted and murdered in Arlington, Texas.
