看到好些前人说双刃剑问题, 刚才有个兄弟又提了

刚刚做了一套GWD, 发现果如其然!!!!有个cr是以前的题,情不自禁就是开始会议答案, 无论如何都读不进去, 选项还挺绕了!!!吓的我一身冷汗! 真的是读不到脑子里, 其他没做过的,反而效率特好, 这套只错了几个, 基本还都是争议题

开始害怕了! 我试过读出声来, 不行! 堵住耳朵, 不行! 再提高注意力,也不行!!! 总之心理暗示极强!!!!!!!!!

怎么办?????大家谁有好办法!!!!!!!!

就这题

24-15 Healthy lungs produce a natural antibiotic that protects them from infection by routinely killing harmful bacteria on airway surfaces.  People with cystic fibrosis, however, are unable to fight off such bacteria, even though their lungs produce normal amounts of the antibiotic.  The fluid on airway surfaces in the lungs of people with cystic fibrosis has an abnormally high salt concentration, scientists hypothesize that in high salt environments the antibiotic becomes ineffective at killing harmful bacteria.

 

Which of the following, if it were obtained as an experimental result, would most decisively undermine the scientists’ hypothesis?

 

1. Healthy lungs in which the salt concentration of the airway-surface fluid has been substantially increased are able to reestablish their normal salt concentration within a relatively short period of time.

2. The antibiotic produced by the lungs is effective at killing harmful bacteria even when salt concentrations are below levels typical of health lungs.

3. The salt concentration of the airway-surface fluid in the lungs of people who suffer from cystic fibrosis tends to return to its former high levels after having been reduced to levels typical of healthy lungs.

4. The lungs of people who suffer from cystic fibrosis are unable to fight off harmful bacteria even when the salt concentration is reduced to levels typical of healthy lungs.

The salt concentration in the airway-surface fluid of people whose lungs produce lower-than-average amounts of the antibiotic is generally much lower than that typical of healthy lungs.

是D,这题静下心来答案是挺明显的

但是题读不进去,情况就不同了

记得第一次做的时候,逻辑线路很清晰;这次是怎么都读不进去,怕呀.........
