Numbers are pronounced and written differently in different languages. Some scientists believe that languages that represent different cultural backgrounds can affect how people's brains process mathematical information. Which of the following, if true, would best support the above conclusion? ['Compared to Europe, people in Asia have different levels of activity in individual regions when comparing numbers.', 'In the same country, when people in different dialects perform mathematical operations, the neural transmission routes in the language area of the brain are not very consistent.', 'The study found that English-speaking people mainly rely on the language area of the brain when performing mental arithmetic, while Chinese-speaking people mainly use the visual information recognition area of the brain.', 'Research finds that people with different professional backgrounds choose different ways of thinking when calculating mathematical problems, but they all depend on the language area of the brain to varying degrees.']
