Which concept explains how languages evolve over time and can be studied by comparing languages to infer ancestral traits?

• A. Universality of Linguistic Structures
• B. Language Family
• C. Potential For Differences among Languages
• D. Syntactic System

Answer: (C)

The idea being tested is how languages evolve over time and how comparing languages can reveal ancestral traits. This fits best because it’s the variation among languages—the differences—that researchers use to trace relationships and reconstruct older forms. By examining how words, sounds, and grammar differ across languages, linguists infer common ancestors and map out how languages changed and split over time. Universality of linguistic structures focuses on what languages share rather than how they got that way. A language family groups related languages, but that alone doesn’t explain how to infer past forms from present differences. A syntactic system deals with grammar within a single language, not the cross-language comparison used to reconstruct history.
