A student is looking for 'paradigm'. They find a dictionary page with guide words 'parachute' and 'paradox'. They reason, 'Since 'paradigm' and 'paradox' both start with 'para-', my word must be here.' Why is this an example of the 'Speed Reading vs. Careful Comparison' pitfall?
A.The reasoning is correct; the word is on the page.
B.The student should have used a thesaurus instead of a dictionary.
C.The student failed to compare the words beyond the first four letters, missing that 'paradiGm' comes alphabetically *before* 'paradoX'.
D.The student correctly identified the shared prefix but ignored the first guide word, 'parachute'.
