Final answer:
The statement associating the ability to detect unique characteristics of two objects with discrimination is true, especially in biological classification where such discernment allows for clearer categorization based on distinct traits.
Step-by-step explanation:
The ability to detect the unique characteristics of two objects is most associated with discrimination. This statement is true. In biological terms, and specifically when looking at a group of organisms, the distinction between different entities is often key to creating an effective classification system.
For example, the pattern of variation in a group of organisms can indicate whether or not it's possible to classify them accurately into distinct groups. If there are clear 'gaps' or differences in the distribution of a characteristic, such as size, then it is easier to classify organisms into categories or taxa since the distinction between them becomes more discernible.
