AFCT English Complete Practice Test Guide

Context clues provide readers with hints or information in the surrounding text that aids in understanding the meaning of unfamiliar words. By examining the sentences or phrases around an unknown word, readers can infer its meaning based on how it is used in context. This skill is essential for reading comprehension, as it enables individuals to expand their vocabulary and grasp the text fully without having to rely on a dictionary for every unfamiliar term.

The other options do not accurately represent the primary function of context clues. Ignoring unfamiliar words would not enhance understanding and can lead to confusion. While finding main ideas is a crucial reading skill, it is distinct from the role of context clues. Identifying the author's intent involves an analysis of tone, purpose, and style rather than simply deciphering vocabulary. Therefore, the correct answer emphasizes the invaluable skill of using contextual information to interpret and understand new words.
