Which of the following statements is NOT true about the survey?
Measuring people’s sense of smell in later life could help doctors predict how likely they are to be alive in five years’ time, a PLOS One study suggests. A survey of 3, 000 adults found 39% with the poorest sense of smell were dead within five years — compared 19% with moderate smell loss and just 10% who identified odors correctly.
And despite taking issues such as age, nutrition, smoking habits, poverty and overall health into account, researchers found those with the poorest sense of smell were still at greatest risk.
Lead scientist, Prof. Jayant Pinto, said: "We think loss of the sense of smell doesn’t directly cause death, but it is a harbinger, an early warning system that shows damage may have been done. Our findings could provide a quick inexpensive way to identify patients most at risk. " Exactly how smell loss contributes to lifespan remains unclear, but the researchers put forward a number of possible reasons behind the link.
They say a reduced ability to sniff out odors could signal less regeneration or repair of cells in the body overall, as a healthy sense of smell depends partly on a continual turnover of cells that line the nose.
And a worsening sense of smell may serve as a mirror for a lifetime’s exposure to pollution and bugs, they say.
选项
A、39% of the surveyed were dead in 5 years.
B、10% of the surveyed identified odors correctly.
C、39% of the surveyed has the poorest sense of smell.
D、19% of the surveyed has complete smell loss.
答案
D
解析
判断题实际上是四个小的事实细节题。本题考查了实验中三个与数字有关的细节。在3000个参与实验的人中,39%嗅觉不灵敏,且在五年内死亡,所以选项A和C正确。10%的人嗅觉正常,B选项也正确。原文指出19%的人有轻度的嗅觉缺失,而D选项“19%的人嗅觉完全缺失”与原文有很大的出入,表述有误。
