31. Which list is best categorized as Tier 2 vocabulary?

Answer: C

Explanation:

Categorized as Tier 2 vocabulary, the list includes abolish, evidence, and scarce.

Tier 2 vocabulary consists of words that are more sophisticated than everyday language and are commonly found in written texts. The terms "abolish," "evidence," and "scarce" fit this description as they are used across various academic subjects and provide nuanced meanings that enhance comprehension.

A) Clock, baby, circle

This option includes basic, concrete nouns that are commonly used in everyday conversation. These words do not convey complex or abstract concepts, which is essential for Tier 2 vocabulary classification.

B) Fibula, aorta, pulmonary

While these words are relevant in specific contexts such as anatomy and biology, they are categorized as Tier 3 vocabulary. Tier 3 vocabulary consists of domain-specific terms that are not commonly used outside of their respective fields.

C) Abolish, evidence, scarce

This option correctly represents Tier 2 vocabulary as these words are versatile in use across different subjects and contexts. They are abstract concepts that enhance language and comprehension, making them suitable for this category.

D) Ecosystem, photosynthesis, biotic

Similar to option B, the terms in this choice are specialized and related to specific scientific fields, particularly biology. These words do not fall under Tier 2 as they are less frequently encountered in general discourse.

Conclusion

The correct answer, C, effectively illustrates Tier 2 vocabulary due to the words' broader applications and their presence in various academic contexts. Options A, B, and D fail to meet the criteria for Tier 2 vocabulary, either being too simplistic or too specialized, reinforcing the distinction between the tiers of vocabulary.
