Questions 21-25 are based on the following text.

    A hospital is a medical service institution to treat patients with health problems, such as illness, injuries, and pregnancy problems.

    The word "hospital" originated from Latin word hospitalis, meaning guests and their treatment. Initially, hospitals were not merely used as a place to cure illness, but as safe place for indigent people or tired travelers. The ·first hospital was built in Greece and called aescupalia. It was named after the Greek God of Medicine, Aescupalus.

    In hospital, paramedics, such as nurses, doctors, and other medical staff, treat inpatients, who need special treatment monitoring, and outpatients, who require treatment, but do not need to stay in the hospital.

    Hospitals have several medical departments, such as emergency rooms, general surgeries, maternity, diagnostics, and anesthetics. Patients who need urgent treatment are sent to emergency rooms that operate 24 hours a day. The doctors are trained to diagnose health problems fast and the nurses are skillful in treating patients. This department applies triage that prioritizes patients with serious illness or serious injuries, when more emergency patients arrive than each department can handle.
