Answer: Hello! I think that Eric would be helped most when using a thesaurus.
Explanation: Words within a thesaurus don't always have antonyms, but Eric's situation would be most ideal to use one of the books.
If Chloe wanted to find an in-depth definition of "boring", they would likely have to use a dictionary.
Sydney would have to look somewhere else to see "vibrant" used in a sentence, as thesauruses don't normally have sentence examples (as far as I remember).
Rico also wouldn't have much luck with trying to pronounce "unanimously" correctly, as teaching someone to say a word properly is not a thesaurus.
I hope that this helps! Good luck with your assignment! :)
