This question appears in the OG VR 2nd Ed.
OA is C

OE is "The sentence presents three functions of intelligent computers,(to diagnose .. deciding .... or other purposes) but they are not written in parallel form. The final function is vague, so turning this into an introductory clause (used for such purposes as ...) and using parallel forms (daignosing/deciding) makes a better sentence.

It clearly mentions, either "as an expert does" or "like an expert" have been used correctly and idiomatically in the choices. .

So dont fret :shock:

(A) 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 ---First indication is the faulty parallelism. --- To diagnose, an infinitive, and deciding, a simple gerund and or other purposes, a noun --- three different forms in a single list. Secondly the wrong comparison of computers to what an expert does


(B) as an expert does, which may be used for purposes such as diagnosing equipment breakdowns or deciding whether to authorize a loan ---- 1. What is the specific antecedent of ‘which’? Is it referring to artificial intelligence or computers. Obviously not to experts or to proponents, since we don’t refer human beings by ‘which’. 2. The comparison issue as in A.


(C) like an expert—computers that will be used for such purposes as diagnosing equipment breakdowns or deciding whether to authorize a loan – The parallelism is set in place smugly by using two gerunds such diagnosing and deciding. The comparison is also correct in comparing the computers to an expert. Correct choice.

(D) like an expert, the use of which would be for purposes like the diagnosis of equipment breakdowns or the decision whether or not a loan should be authorized --- 'The use of which' is a problem as in B. 2.'Like' to denote example is another issue.

(E) like an expert, to be used to diagnose equipment breakdowns, deciding whether to authorize a loan or not, or the like -- 1. Parallelism: 1. to diagnose 2. deciding or 3. the like – not parallel. 2. It is not clear what the term ‘to be used’ refers to an expert or to computers or to intelligence

There are two things about this problem that have always interested me:

1) The split between "like" and "as" is a fakeout! We don't need to decide that to get the problem right, and in fact either one could work! You can reason "like an expert" or "as an expert does." What's really at issue is how we follow up on this comparison. In B, D, and E, we are using the expert, when it seems we should be using the computer. That leaves us with just two choices!

2) The other interesting bit is how the dash is used here. For some reason, the Verbal Review book seems to feature the dash more prominently than the main OG, and it's put to interesting use. The dash--not a hyphen, but a long dash--is often used as a parenthetical, as in this sentence you're reading. :) However, it can also be used to indicate a break in the sentence that increases clarity. In the case of this problem, we need to make it clear that we're talking about computers, not experts, so we use a dash to break in and reintroduce the subject again. If you're not sure why we're doing that, take a look at how we'd have to write C without the dash:

Proponents of artificial intelligence say they will be able to make computers that can understand English and other human languages, recognize objects, and reason like an expert and that will be used for such purposes as diagnosing equipment breakdowns or deciding whether to authorize a loan.

Technically, we could say that we had done our job. We have parallel clauses: "that can understand . . . " and "that will be used." However, there's so much complexity in between that it becomes very hard to understand what we're trying to say. If we think of good grammar as a form of good manners, the dash is our way of leading the reader politely to our intended meaning.

There's one thing stumping me about this question:

Saying that a computer "can X, Y and Z, LIKE an expert" - doesn't this compare the actions of the computer directly to an expert........in other words, I wanted to make the comparison such that it compared the actions of the computer to the ACTIONS of the expert.

I'll appreciate any help on this

Hello nrxbra001,

I am not sure if you still have this doubt or not. Nonetheless, he is the explanation. :-)

In comparison, there are two entities that are compared because of some point of similarity.

In this official sentence, the two compared entities are certain experts and certain computers.

Why have they been compared? They have been compared because they both can perform certain tasks in the same manner.

Hence, this comparison can be expressed both ways:

Like experts, computers can do A, B, and C.

As experts do, computers can do A, B, and C.

It is so because the basis of the comparison is what these two entities can do. So the computers have been compared to the experts because both can perform the same tasks. The action is inherent in the comparison.


Hope this helps. :-)
Thanks.
Shraddha
