So to better untangle the relationship between drinking and sweating, researchers at Pennsylvania State University, in the most scientifically ambitious of the new studies, turned to a representative group of 150 adult men and women aged 18 to 75 who already were enrolled in an ongoing, long-term health study at the university. They asked these volunteers to visit the lab and fill out extensive questionnaires about their lifestyles, and then provided each of them with a simple smartphone app that could be used to record a day's drinking and exercise activities. The app would automatically send each day's report to the scientists.The volunteers agreed to use the app for 21 consecutive days. Over the course of about a year, covering different seasons, each participant completed three of these 21-day reports. When the researchers collated and compared the data from their volunteers, they found, for the first time, an unequivocal correlation between exercising on any given day and subsequently drinking, especially if someone exercised more than usual. As the scientists write in their study, which was published recently in Health Psychology, "people drank more than usual on the same days that they engaged in more physical activity than usual."50. What is the passage mainly about?A. The development of people's drinking habits.B. The differences between the two studies.C. The close ties between exercise and drinking.D. How to do research in a scientific way.
