Which type of context clue helps determine the meaning of the word 'obsolete' in a sentence?

The type of context clue that aids in determining the meaning of the word "obsolete" is an example. When a sentence provides examples of how something is no longer in use or has been replaced, it can clarify the meaning of "obsolete." For instance, if the sentence describes outdated technology or practices that have been superseded, it gives a concrete reference which helps to understand that "obsolete" relates to something that is no longer relevant or effective.

Context clues like lists and antonyms also serve important roles in understanding meaning; however, in this case, examples specifically illustrate the concept of obsolescence. Synonyms might reinforce understanding but do not provide the same level of clarity regarding the shift in relevance or usage implied by the term "obsolete".
