premise:most diamond is assessed by seller-->unfair price
conclusion:diamonds sold at GW certified in writing-->fair price
prephrase:certified in writing has nothing to do with seller,otherwise undermine the

conclusion
A similarity between other stores and GW-->weaken
B certification -->irrelevant
C higher quality-->irrelevant
D price changes-->irrelevant
E as was said in prephrase-->support

---->E

premise:repainted--->no other work can be done at the same time
conclusion:nontoxic paint-->can be done at the same time-->reduce maintenance time
prephrase:1other factors make other works can not be done at the same time
2 even done at same time, can't reduce maintenance time
A color-->irrelevant
B remove-->irrelevant
C technicians-->irrelevant
D protection needed-->irrelevant
E film paint has good quality,thus don't need further maintenance-->support

----->E  wrong!!
E doesn't compare film with paint, film has high quality doesn't mean it is better than

paint! And I was putting additional assumption to E choice, that good quality helps reduce maintenance time.

B is comparing, and the point of B is not the removal but the comparison!
I need practice more on picking point!!

ps.Actually there is an implication: paint will be first removed and then repainted in

repainting, so the removal time also matters to maintenance time. So decreasing the removal

time could also help achieve the goal:to reduce maintenance time.

key--->B

premise: invest in C-->considerable investment,farmers can't afford service fees ----> CTCo.

can't make profits
However, contends consider the investment profitable
prephrase: company can make profits through other way than services fee.
A predict<--->current situation, forced to pay doesn't mean profitable--->out of scope
B other fixed-line telephone service-->irrelevant
C can't understand,retain it
D base fees on...-->seems relevant,but it doesn't show supports
E historical<-->predict-->irrelvant

---->C,but I'm not sure,         wrong again!!!
C选项是说Calex可以用比fixedline更少的签约客户就可以达到收支平衡，可是这不能解决农民没钱的问题。比如fixed line的成本需要10个客户的service fee才能收支平衡，而Calex可以用5个客户的service fee就达到收支平衡了。本质上，1个能付得起的都没有，所以它需要的subscriber少.
A：农民没有电话不能跟外界高价的买家联系，所以会想办法付钱，直接割断了 can’t afford和make profits的逻辑链，使contend被支持

info1:similarities-->BH took idea from T
info2:production work on the BH was completed before T was released--->accusation is without

merit
prephrase:before T was released ,its information had not been know by BH's director
similarities cannot be evidence for accusation
A weaken
B since similarities are related to other earlier films of the same genre, similarities could

not be used as reason to accuse BH's director---correct
C film studio of T-->irrelevant
D earlier projects-->irrelevant
E time-->irrelevant

this question has two approaches,1 .weaken the info1;  2.support info2.  so both info are

important,don't overlook any of them
---->B

60% samples from meso contain sv40--->asbestos is not the cause of meso & sv40 is the cause

of meso
sv40 is a monkey v,however, pv was contaminated with v--->pv was the source of v found in

meso
the point of argument is to legistimate the hypo
prephrase: is the evidence from sample valid?
A cancer-->irre
B changes-->irre
C seems good
D seems support that sv40 is the cause of meso
E it support hypo from reversed situation-->better than CD
---->E

premise:water pollutant in the past five years, high rate of new cases of certain disease
conclusion:water pollutant is responsible for disease
prephrasether factors could have also caused disease
in neighbour city, where the water was also polluted, people is healthy
A support
B support
C not support
D seems support
E support
I can't figure out wether D is supporting ,but I am sure C is not supporting.
--->C

about D ,it means that the disease is not caused by other factors related to private sources,

ruling out other possible factors thus strengthening the  hypo.
