单选题 Which of the following is Not true according to the first two paragraphs?

A、 Gordon's purpose in his study of the Piraha was to solve a language problem.
B、 The Piraha would use the word "many" to describe the number "twenty".
C、 Linguists had studied other languages before they switched to Hopi.
D、 Whorl claimed that language did more than influence people's thought.

【正确答案】 C

【答案解析】这是一道是非判断题。依据段二句二，是Whorf而非其他语言学家研究Hopi语言，所以C项不符合文章内容，为答案。
