Answer:
Excitement or increased activity.
Step-by-step 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 when we want to save the time spent looking up words in the dictionary or in any other source.
In the sentences, the context clues provided to infer the meaning of the word “stimulation” are mainly “exhausting” and “sensory overload.” Therefore, from all options, the correct meaning of the word “stimulation” is “excitement or increased activity.”
