Develops when normally elastic connective tissues are replaced with nonelastic fibrous tissues.

Contracture develops when normally elastic connective tissue are replaced with nonelastic fibrous tissues. 
Contracture is the prolonged state of shortening or tightened tissue. Contracture develops when the normally stretchy tissues are replaced by non stretchy fiber-like tissue. This tissue makes it hard to stretch the area and prevents normal movement. It mostly occurs in the skin, the tissues underneath, and the muscles, tendons, ligaments surrounding a joint. 

A contracture develops when normally elastic connective tissues are replaced with nonelastic fibrous tissues.
A contracture is a deformity which forms as the result of stiffness or constriction in the connective tissues. This can occur in muscles, tendons, ligaments, and skin. As a result, contracture deformity restricts normal movement because pliable connective tissues become less flexible.

The answer is observations and interpreting.
