albert, CXD的假设,有几题不清,能帮我看看吗?
T50 D?
T52 C?
T72 C?
谢谢.
I almost finished the answer,but the brower close automatically...sad...I have to retype again... T50 because genetic susceptibility will be counteract, the illness will disappear...
there is a gap between genetic susceptibi8lity and illness... D is not necessary condtion because even though some humans are NOT susceptible to some disease, the conclusion still holds...we should focus on the relation between susceptibility and illness, but NOT human and disease...
T52.
from the passage we know that flying time is a required fator to the safety of airline, but not sufficient condition...In another word, lack of flying time will lead to the crash of airline, however, enough flying time will not certainly give rise to the decrease of airline crash...maybe several factors together with flying time determine the safty of airline...So CHOICE C is a sufficient condition but not an required condition... This is a common trick in GMAT CR...think twice...we should notice that differece of sufficient condition and required condition to identify the assumption correctly
T72 a quite long passage...we should dig out some useful information to make a clear picture of this argument
evidence: 1. peer review is required condtion to protect public health 2. medical publication will occur after the peer review coclusion: to protect publice health, we should wait for the medical publicaiton...
from the information above, we notice a GAP.. we noly need the peer review, but we should wait for the publication... assumption: publicaiton is an required condition of the peer review..in another word, without publication, peer review will not occur, as A says.
C.. from the line of reasoning above, we should know know that the access of public to the medical journals is irrlevant to this argument... we should focus two key words: peer review and publication ...C is easy to eliminate if we notice that it is talking about another key words...access of public
good luck!
