Answer:
c. saving the time spent looking up words.
Explanation:
Context clues is a technique used when reading that consists of looking at the surrounding information of an unknown word (such as phrases, synonyms, antonyms, and definitions) in order to infer its meaning. This technique is very helpful for students who want to read more in the least amount of time because it saves the time spent looking up words in the dictionary or in any other source. Context clues, however, can not be used always as there are more complex subjects, like science, that present words whose meaning can only be clarified if we look it up in a dictionary.
