Which of the following sentences is written in formal language?

Rationale

Modern mathematics encompasses numerous scholarly disciplines; however, discrete mathematics is often disregarded.

This sentence employs formal language through its sophisticated vocabulary and structured syntax, making it appropriate for academic or professional contexts. It demonstrates a level of formality and complexity that distinguishes it from more casual expressions.

A (There are various branches in social science such as anthropology, sociology, and psychology.) YOUR ANSWER

While this sentence is informative, it uses a more conversational tone. The phrase "there are various branches" lacks the formal structure and elevated vocabulary that characterizes formal writing.

B (During the culinary arts class, the instructor had us sample a delicacy, caviar!) YOUR ANSWER

This sentence is informal primarily due to the exclamation mark and the casual phrase "had us sample." The use of "delicacy" does introduce some sophistication, but the overall tone remains light and conversational, which is not indicative of formal language.

D (My economics instructor mentioned that purchasing a car can be more cost-effective than renting one.) YOUR ANSWER

Although this sentence contains some formal elements, such as "cost-effective," it still maintains an informal tone with the use of "my" and the phrase "mentioned that." The structure is straightforward and lacks the complexity typically found in formal writing.

Conclusion

Formal language is characterized by sophisticated vocabulary and a structured, impersonal tone. Among the provided choices, option C stands out as the only sentence that fully embraces these qualities, making it suitable for academic discourse. The other options, while informative, do not meet the criteria for formal language due to their conversational tone and simpler structure.
