Friction and reflectiveness are the correct answers for question no. 26 and 27.

What is the role of friction?

It is harder to push a box up a ramp with a rough surface as compared to a smooth surface because the rough surface provides more friction that is the force opposite to the motion.

A boy can see his face when he looks into a mirror due to the reflectiveness property of the mirror that makes this happen because a boy see his reflection in that mirror.
