Q: Read the following article and answer the question. Article: It is not unusual for people to speak two or three languages; they're known as bilinguals or trilinguals. Speakers of more than three languages are known as polyglots. And when we refer to people who speak many languages, perhaps a dozen or more, we use the term hyper-polyglot. The most famous hyper-polyglot was Giuseppe Mezzofanti, a 19thcentury Italian cardinal, who was said to speak 72 languages. This claim sounds absurd. _ But Mezzofanti was tested by critics, and they were all impressed. Did Mezzofanti have an extraordinary brain? Or are hyper-polyglots just ordinary people with ordinary brains who manage to do something extraordinary through hard work? U.S. linguist Stephen Drashen believes that outstanding language learners just work harder at it and then they acquire unusually strong language ability. As an example, he mentions a Hungarian woman who worked as an interpreter during the 20thcentury. When she was 86, she could speak 16 languages and was still working on learning new languages. She said she learned them mostly on her own, reading fiction or working through dictionaries or textbooks. Some researchers argue to the contrary. They believe that there is such a thing as a talent for learning languages. In the 1930s, a German scientist examined parts of the preserved brain of a hyper-polyglot named Emil Krebs, who could speak 60 languages fluently. The scientist found that the area of Krebs's brain called Broca's area, which is associated with language, looked different from the Broca's area in the brains of men who speak only one language. However, we still don't know if Krebs was born with a brain ready to learn dozens of languages or if his brain adapted to the demands he put on it. Although it is still not clear whether the ability to learn many languages is in born, there's no doubt that just about all of us can acquire skills in a second, third, or even fourth language by putting our mind to it. Question: The Hungarian woman became a hyper-polyglot mainly because of her _ . Answer:

hard work
