Answer to Question 1

In a longitudinal study, participants can drop out of the study and repeated testing can distort the results. Neither of these problems would be a factor in a cross-sectional study.

Answer to Question 2

3-year-old description of a best friend: He plays with me and is nice to me.
10-year-old description: He helps me with my homework, keeps secrets, and shares his snack at school.
16-year-old description: I can tell him anything. He makes me feel better when I am down. We've got each others' backs.
