True or False: Small, microscopically unique markings can be traced directly to the object or instrument responsible.

The statement is true because small, microscopically unique markings can indeed be traced back to the specific object or instrument that created them. In forensic science, this concept is vital in the analysis of tool marks, firearms, and other items that leave distinctive impressions or scratches when they come into contact with surfaces. These unique characteristics arise from the manufacturing process, wear and tear, and specific usages of the tool or object, making them individual identifiers. Forensic analysts utilize these markings to match a tool or weapon to its evidence, often providing critical links between the item, the crime scene, and the suspect. This reliability of microscopic markings is a foundational principle in forensic investigations, demonstrating how these tiny details can serve as substantial evidence in criminal cases.

While the other options hint at varying degrees of certainty or contextual dependency, the essential takeaway is that under the right circumstances, microscopic marks are a powerful tool in forensic analysis.
