The Sapir-Whorf Hypothesis
The Sapir-Whorf hypothesis is based on the idea that people experience their world through their language, and that they therefore understand their world through the culture embedded in their language. The hypothesis, which has also been called linguistic relativity, states that language shapes thought. Studies have shown, for instance, that unless people have access to the word “ambivalent,” they don’t recognize an experience of uncertainty due to conflicting positive and negative feelings about one issue. Essentially, the hypothesis argues, if a person can’t describe the experience, the person is not having the experience.
Q. The word they refers to …
B is correct because the pronoun “they” refers back to “people”, which is in the same sentence but comes before the pronoun referent.
