Answer:
Using context clues is helpful when you do not have a dictionary nearby to look up the meaning of a word.
Step-by-step explanation:
“Context clues” is a technique used when reading that consists of looking at the surrounding information of an unknown word in order to infer its meaning. This technique is very helpful when we do not have a dictionary that gives us an accurate explanation of a word's meaning, and when we want to read more in the least amount of time because it saves time spent looking up words in the dictionary or in any other source. Context clues, however, can not be used always. Texts about complex subjects like biology sometimes have words whose meaning can only be clarified if we look it up in a dictionary.
