Middle adolescence is characterized by
a. feelings of invincibility
b. simple thinking processes
c. increasing conflict with parents
d. logical, mature decision making

Middle adolescence is chracterized by increased conflict with parents - c.

What is also characteristic, although perhaps to a lesser extent is these feelings of invincibility. 

However, more often it is present that teenagers would report and say they have been having more conflicts with their parents as was usualy for them to do so in the past.

Ifeel like this means that we shouldn't just live for ourselves.also, we should respect others as well as people around us. it reveals that everyone should have equalized freedom, no matter their differences: races, cultures, skin color, etc,. we all deserve the same privileges.
