Question

Which statement about the onset of puberty is true?

1) Most girls in developed countries are uninformed about puberty.
2) Girls usually get information about puberty from reading material or websites, whereas most boys get it from their mothers.
3) Although almost all boys tell a friend about spermarche, far fewer girls tell friends that they are menstruating.
4) Overall, boys get much less social support than girls for the changes of puberty.

Answer 1

The onset of puberty typically begins at an average age of 10 for girls and around 11 to 12 for boys. Girls usually complete puberty in about 4 years, whereas boys take about 6 years. Menarche, the first menstrual period, is a significant change, occurring roughly at ages 12-13 for girls; boys experience spermarche around ages 13-14.

Step-by-step explanation:

The statement about the onset of puberty that is true is that girls begin puberty a year or two earlier than boys, on average around 10 years of age, and complete it sooner, typically in about 4 years as opposed to 6 years for boys. Puberty involves the maturing of the adrenal glands and sex glands, and the development of both primary and secondary sexual characteristics. For girls, one of the most significant changes during puberty is menarche, the first menstrual period, which occurs around the average age of 12-13 years old. In contrast, boys experience spermarche, the first ejaculation, around 13-14 years old.

The accurate statements from the question options are not provided, but based on the information given, we can infer that girls usually do receive information about puberty, albeit the source of this information (parents, school, reading material, or websites) varies and is not specified in the options provided. Additionally, societal norms and personal comfort levels may influence whether children discuss puberty changes such as menstruation or spermarche with friends.
