Final answer:
The conclusion that a victim touched an object based on their fingerprint would be reached through inductive reasoning, a logical process used to make generalizations from specific observations.
Step-by-step explanation:
The conclusion that a victim definitely touched an object upon which their fingerprint is found would be reached through a process known as inductive reasoning. This type of reasoning involves making a generalization based on specific evidence. In this case, the specific evidence is the fingerprint, and the general conclusion is that the victim touched the object. While inductive reasoning allows for broad generalizations and can sometimes lead to incorrect assumptions, it is the method used in everyday inferences and scientific discovery to formulate theories and hypotheses from observations.
