Who remembers this stuff?

Deckchair Danny aka Laura B is conducting some research for a class:

We are conducting this survey on menarche (first menstrual period) as part of a research project for our anthropology class at Whatcom Community College. Over the last 150 years, there has been a reduction in the average age at which girls have their first menstrual period. We hope that your answers to the following questions will help us to understand some of the factors. Thank you very much for your participation.

Well, I definitely can't answer many of these questions. Can you?

Maybe the questionnaire isn't aimed at women of my advanced age . . .
