This is one among those questions which scare me like hell
first lets see what is being compared... the reasoning of the system with the reasoning of an expert. and not with an expert itself.
so, '...reason like an expert' seems incorrect to me.. becasue it should be '... reason like an expert does'... so it eliminates choices C, D, and E.
Now left with A and Bthey don't have this particular issue about comparision... however B is incorrect because the word 'which' follows expert...
choice 'A' looks perfect to me... one independent clause in red and a dependant clause in blue.
Proponents of artificial intelligence say they will be able to make computers that can understand English and other human languages, recognize objects, and reason as an expert does
-computers that will be used to diagnose equipment breakdowns, deciding whether to authorize a loan, or other purposes such as these.
However i am not sure can i use '-' a dash to join two clauses... this seems okey in novels etc.. but not sure if ETS accepts this?? Any suggestions will be greatly appreciated.
I am wondering is this sentence incorrect.. " he runs like a deer' or should it be "he runs like a dear does"...??
