According to a survey conducted by the relevant Shanghai authorities on the mortality rate of people with different marital status between 25 and 64 years of age, the death rate of widowed and divorced people is significantly higher than that of those with spouses. The total standardized death rate of widowed people is 880 / 100,000, 3.2 times the spouse population; the total standardized mortality rate for the divorced population was 8.7 per 100,000, which was 3.1 times that of the spouse population. The correct inference from this is:. ['More widowed than divorced.', "A healthy marriage is good for people's physical and mental health.", '.1 times more spouses than divorces.', 'The average life expectancy of people is getting higher and higher.']
