Why was a husband's character so important in determining a woman's life in the early nineteenth century

During the 19th Century women had fewer rights than they do today. Also, it was more common for them to stay at home overseeing domestic duties such as cooking, cleaning and so on.

For this reason, women had to count on their husbands to provide for the family. So they needed husbands who could provide for them and their family.

The correct answer is “US Supreme Court”

The US Constitution does not specificity that the US Supreme Court justices have a lifetime appointment. It only states that federal judges “shall hold their Offices during good behavior” but it does not set a specific term or age limit service. In practice, as long as a federal judge does not commit a crime he/she will keep their seat.
