Hi, i have a social studies test and need to get it right so here is the question. how was the invention of the wheel important to the summerians? a. it allowed them to conquer neighboring states. b. it made traveling with traded items easier and increased trade. c. it improved their communication and recordkeeping. d. it them to water their crops all year.

i type the answer in the comments but for now i have to check the answer and work on my own question

i disagree that there is little difference between adult female development and adult male development. sociological studies comparing female and male pathways to adulthood, revelead that there are sustancial differences between them. particularly, female and male differ from timing of marriage, when they began to live with children and the likelihood of combining wife/husband and parent roles.
