According to urban sociologist Jeffrey Lane, what gender difference exists among teenagers in Harlem?

a. Boys were more visible and acted more dominant toward girls on the sidewalk than online.

Explanation:

In his study about The Digital Street, Jeffrey Lane researched the behavior of teenagers online and on the street in the neighborhood of Harlem).

He found out that boys will sometimes behave aggressive and dominant on the streets towards the girls (like calling out or grabbing their hands), but then would be nice and talkative online. In the online conversation with the girls, they would sometimes say that they do "stupid things like that" sometimes on the street, but that they are not like that usually.

This is supporting the idea about how digital and offline life are intervened and we have to search through both to see the full picture.
