Final answer:
The statement is false; metals are modified to increase their resistance to shearing, forces of torque, and deformity to enhance their malleability and ductility.
Step-by-step explanation:
The statement that metals are modified to decrease resistance to shearing, forces of torque, and deformity is false. Metals are generally modified to increase their resistance to these forces, enhancing their malleability, ductility, and resistance to shearing. The modifications help ensure that the metals can withstand the various stresses they encounter without breaking or deforming easily. For instance, the free-flowing electrons in metals allow them to be hammered into shapes, rolled into thin sheets, or drawn into wires, which demonstrates their malleability and ductility. The addition of certain alloys can further increase a metal's resistance to shearing and deformation, which is essential in many industrial applications.
