Whichofthefollowing,iftrue,mostseriouslyunderminesthejournalist'sargument?
(A)Everyarticlebasedonexperimentswithparticleacceleratorsthatwassubmittedforpublicationlastyear actuallywaspublished.
(B)Theaveragetimescientistsmustwaitforaccesstoaparticleacceleratorhasdeclinedoverthelast severalyears.
(C)Thenumberofphysicsjournalswasthesamelastyearasinpreviousyears.
(D)Particleacceleratorscanbeusedformorethanonegroupofexperimentsinanygivenyear.
(E)Recentchangesintheeditorialpoliciesofseveralphysicsjournalshavedecreasedthelikelihoodthat articlesconcerningparticle-acceleratorresearchwillbeacceptedforpublication.
D. E.两项不但跟结论有关,而且紧扣premise,且D直接驳斥结论。
为何为E
P。S。有大牛说,D的漏洞在于不是研究了就一定能发表,所以解释了low number of articles.
但是在实战中到底怎么判断conclusion中的最致命的驳斥点呢?
