다음 글의 제목으로 가장 적절한 것은? Doctors have been advising us for years to “use it or lose it”: that is, to stay as intellectually active as possible into our waning years in order to avoid dementia. But the latest research shows that brain training comes at a price. In a study of 1,157 men and women age 65 or older, researchers found that people who remained intellectually stimulated—by playing cards or other games, reading or visiting museums—were diagnosed with dementia later than those who were not as cognitively active. But once dementia set in, the group who participated in mentally stimulating activities experienced a much more rapid cognitive decline. Over the 12-year study, the intellectually stimulated group experienced a 52% greater decline in cognitive impairment, after being diagnosed with dementia.
③Cognitive Training Does Not Always Increase Brain Function
④Brain Exercises Delay, but Can’t Prevent Dementia
⑤Early Diagnosis and Treatment for the Elderly with Dementia Needed

첫번째정답의단서는…But the latest researchshows that brain training comes at a price. 최근의연구에의하면두뇌훈련은비용이든다[대가를치른다]는것이다. 두뇌훈련이만능이아니라는점을암시하고있다. *come at a price 대가가따르다
Butonce dementia set in, the group who participated in mentally stimulating activities experienced a much more rapid cognitive decline. 하지만일단치매가들어선경우, 정신적으로활발한활동에참여했던사람들은훨씬더급격한지적인감소를겪었다.
두번째 But에서정답을확인할수있다. 두뇌훈련은치매를늦출수는있지만치매를막을수는없다는것을알수있다.
