請依下文回答第 47 題至第 50 題：While many studies have been undertaken to study the impact of consuming coffee on our health, researchers have justadministered the first study that analyzes the effects of coffee’s aroma. For many people, the morning coffee is just thething to wake up the dormant brain cells and to put the body in gear. However, according to the 25th issue of theJournal of Agricultural and Food Chemistry, the smell of coffee also has a comparable, if not more, effect on our body,diminishing the impact of sleep deprivation. At least, that’s what researchers have found in rats.Rats that suffered from insomnia, or inability to sleep, were exposed to the smell of coffee. Coffee aroma successfullyactivated seventeen different genes in their brains; among them, thirteen were known to produce proteins that protectnerve cells from the damaging impact of stress or tension. So, what is the implication of this finding for those peoplewho were stressed by lack of sleep and/or need to stay up late? Well, maybe they do not have to shell out 100 NTdollars for a venti-sized latte to get some of their genes activated in their brains and/or to ease the impact ofsleeplessness resulting from tension. All they need to do is to walk to a coffee shop around the corner and get a sniff ofcoffee.
