Can a coefficient of friction exceed 1.0?????
I have no idea what this means,... please help and explian if you can.

The coefficient of friction is the ratio between the force pressing two objects together and the force of friction between them. In the case of of sliding friction, this is literally the ratio of two forces. However in the case of static friction, this is the ratio of one force (the force pressing the two objects together, also called the normal force) to the maximum force that can be supplied by static friction. The actual force may be less than that. For instance, if the force tangent to the surface is less than the coefficient of friction times the normal force, the actual force of friction will be equal and opposite to the tangent force, and the object won't move.
Anyway, the question asks whether there are any materials for which the coefficient of friction is greater than 1. A simple glance at a reference table, such as the one linked below, reveals the answer is yes.
