Which of the following best summarizes this passage? ?

The correct answer is D: "When language is a barrier, people will find other forms of communication." This choice effectively encapsulates the main idea of the passage, which likely discusses the challenges posed by language differences and the adaptive strategies that people employ to overcome these challenges.

In situations where individuals do not share a common language, relying solely on verbal communication becomes ineffective. Therefore, they often resort to alternative methods such as body language, gestures, visual aids, or even drawing to convey their messages. This highlights the human ability to adapt and seek out solutions when faced with obstacles in communication.

Choices A, B, and C, while touching on aspects of communication, do not address the core theme of overcoming language barriers. A and B focus more on the importance of words or the value of language for foreigners, which is less relevant to the idea of finding alternative methods when language is not an option. Choice C incorrectly suggests exclusivity, implying that everyone uses only one form of communication, which contradicts the notion of adaptability. Thus, D captures the essence of the passage most accurately.
