问题 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、It proves to be a quick way to detect patients at risk.
B、It has found out another deadly disease.
C、It points out an efficient way to extend lifespan.
D、It takes into consideration age and smoking habits.

答案A

解析 Prof Pinto认为该研究的重要意义在于它能够为医生提供快捷、经济的诊断方式,锁定那些死亡风险最高的病人。
