48. Which of the following is the best example of a Tier 3 vocabulary word?
Answer: C
Atom is the best example of a Tier 3 vocabulary word.
Tier 3 vocabulary words are specific to a particular domain or subject area and are often technical in nature. The word "atom" fits this definition as it is a fundamental concept in the field of science, particularly in chemistry and physics.
A) Illustrator
While "illustrator" can be a specific term related to art and design, it is more commonly understood and used in everyday language. It does not possess the same level of technical specificity associated with Tier 3 vocabulary as "atom" does.
B) Mountain
"Mountain" is a general term that refers to a natural geographical feature and is widely used across various contexts. It lacks the domain-specific focus that characterizes Tier 3 vocabulary words, making it an inappropriate choice.
C) Atom
"Atom" is a highly specialized term that refers to the smallest unit of a chemical element, making it a quintessential example of Tier 3 vocabulary. Its usage is primarily confined to scientific discussions, distinguishing it from more common vocabulary.
D) Table
The word "table" is a common noun that can refer to furniture or data organization and is used in everyday language. It does not represent the specialized knowledge or specificity required for Tier 3 vocabulary, thus making it an incorrect option.
Conclusion
The term "atom" is definitively the best example of a Tier 3 vocabulary word due to its specialized meaning in scientific contexts. In contrast, the other options are either too general or commonly used in everyday language, which disqualifies them from being categorized as Tier 3 vocabulary.
