Which have contributed to longer life expectancy? Select all that. fewer deaths
improved health care
improved hygiene
smaller families
cures for some diseases

Improved health care, improved hygeine, cures for some diseases is what i would say.

Explanation: Just kind of common sense. Maybe smaller families but can’t really see how that would help. Also I don’t know like what unit you’re in, so i would just pick what you’ve learned about in the unit and 9/10 times it’ll be correct. good luck

do u have any answer choices man?

        i'm fairly sure that the correct answers are 2 and 3.

        i used both my knowledge of world history and the process of elimination to obtain these answers. option 1 cannot be a possible selection because the mandate of heaven belongs to ancient chinese philosophical belief. option 4 sounds like it would benefit the region than detriment it. however, both 2 and 3 explain a potential reason for what could have contributed to the fall of the roman empire.

      hope this ! if i were you, i'd get a second opinion, because i haven't taken this course for a year. best of luck!
