Third class levers, although mechanically inefficient, offer the benefit of a large excursion in range of motion with little or small changes in muscle length.

This statement is true. Third class levers have a fulcrum on one end, the effort applied on the other end, and the load in between. They provide a large range of motion but require more effort than first class or second class levers. However, they also offer the advantage of allowing muscles to contract over a small distance while producing a larger range of motion at the load end.
