Which of the following statements is NOT true? A. Some 260 million people in the world have an adequate working knowledge of English. B. There are some 260 million native - speakers of English in the world. C. It is almost impossible to estimate the number of people with an adequate working knowledge of English. D. People learn English for a variety of reasons.

The statement that is NOT true is A. Some 260 million people in the world have an adequate working knowledge of English.

According to the reference materials, 260 million refers specifically to the number of native English speakers (e.g., in the US, UK, Canada, etc.) . In contrast, the number of people with an "adequate working knowledge" of English—those who use it as a second or foreign language—is explicitly stated as impossible to estimate due to the diverse contexts and purposes of English learning . For example, document 1 clarifies that "it is impossible to estimate the number of people... who have acquired an adequate working knowledge of English" because learning goals and situations vary widely.

Other options are supported by the text:

B is true: There are approximately 260 million native English speakers .

C is true: Estimating "adequate working knowledge" is deemed impossible .

D is true: People learn English for diverse reasons, including international communication, science, government, and commerce .

This confusion between "native speakers" (260 million) and "working knowledge speakers" (uncountable) makes option A incorrect. How might the definition of "adequate working knowledge" change across different contexts like business versus tourism?
