Final answer:
The phrase 'on the other hand' is not a cue for a synonym context clue, as it introduces a contrast rather than a synonymous term.
Step-by-step explanation:
In the context of a passage, if a writer uses a synonym context clue, they're giving the reader a hint about the meaning of a word by using synonyms or words with similar meaning. The correct answer to the question about which choice is not a cue for a synonym context clue is C. on the other hand. This phrase typically introduces a contrast or a point of comparison, rather than a synonym or explanation.
For example, phrases like 'in other words', 'similarly', and 'likewise' often introduce restatements or clarifications that use synonyms, whereas 'on the other hand' suggests a difference and therefore does not usually provide a synonym context clue.
