Final answer:
The student is using context clues to determine the meaning of an unknown word. Context clues can provide better insight into a word’s meaning within a specific context than a dictionary definition alone. Proper word choice and understanding are crucial for clear communication.
Therefore, option A is correct.
Step-by-step explanation:
When a student uses the words and sentences around an unknown vocabulary word to determine its meaning, he or she is using context clues. Context clues involve looking at the rest of the text to find hints about the meaning of the unknown word. This process can be more effective than solely relying on a dictionary definition, which may not provide the nuance needed for comprehension in a specific context.
It is also important to make smart choices in word usage. One should avoid using complex vocabulary without understanding it fully. Misspellings or incorrect usage of a word due to misunderstanding can lead to confusion for the reader.
