Which of the following statements is NOT true about the survey? [br]
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、Regeneration of cells.
B、High pressure.
C、Damage to the body.
D、Unavoidable death.
答案
C
解析
本题考查的是对实验发现的解释,即为什么嗅觉失灵与寿命之间有联系。研究者认为嗅觉失灵意味着细胞再生能力和修复能力减弱,A选项与此意相反。再结合上文Pinto教授的评论,嗅觉失灵预示了身体已受损害,选项C正确。
