Over the same period in Japan, beds increased from 1 per 1,000 population to 2.9 per 1,000 population. Also during this period, annual mortality rates for persons with mental disorders have risen substantially in the United States, while declining in Japan.

(B) Due to advances in medical care and training over the past three decades, outpatient treatment is more effective than inpatient treatment for many mental disorders.
(C) The incidence of mental disorders in Japan has been decreasing, even as the country has increased the number of beds available for inpatient psychiatric treatment.
(D) Over the past three decades, Japan has offered state-sponsored health insurance to all citizens, while the United States has not.
