Anecdotal evidence suggests that the Buteyko method can reduce asthma symptoms and improve quality of life. In a scientific study to determine the effectiveness of this method, researchers recruited 600 asthma patients aged 18-69 who relied on medication for asthma treatment. These patients were randomly split onto two research groups: one practiced the Buteyko method and the other did not. Patients were scored on quality of life , activity, asthma symptoms and medication reduction on a scale from 0-10. On average, the participants in the Buteyko group experienced a significant reduction in asthma symptoms and an improvement in quality of life. A. Identify the main research question of the study. B.
