We can eliminate choices based on parallelism and intended meaning
and come down to C

But if one starts eliminating choices using 'like' vs 'as' why is 'like' correct usage for this sentence?

This is one issue that is perplexing me. The answer for this question is certainly going to be interesting. I have problems with all choices.

I think 'as' is the correct use here, because the computer's ability to reason is compared to a expert's ability to reason. But both choices A and B dont seem correct.

Quote:
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


I reject A because of parallelism issues.

Quote:
B. as an expert does, which may be used for purposes such as diagnosing equipment breakdowns or deciding whether to authorize a loan


I dont like the usage of 'which' in the sentence. The word it references i.e. 'computers' is not next to the modifying phrase. The parallelism is correct.

Quote:
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 correct. I think the word 'like' is wrong. The computer's ability to reason is compared with the expert.

Quote:
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 correct idiom is 'whether to'. Both usages of 'like' seem wrong.

Quote:
E. like an expert, to be used to diagnose equipment breakdowns, deciding whether to authorize a loan or not, or the like.


I reject E because of parallelism issues.

hmm.. reason is a verb. like is used to compare nouns.

this is the only way that i can see the sentence making sense.

computers (that can understand English, recognize....and..) like an expert.

computers (that can understand English, recognize....and..) similar to an expert.

"As" introduces a clause where as "like " is a preposition.

So "like an expert" denotes a object of preposition.

thanks for the replies.

found a similar question


*Many times, the key to solving As/Like questions lies in the verb DO.
Ms. McClintock reported that genes can "jump," as pearls moving mysteriously from one necklace to another
(A) as pearls moving mysteriously from one necklace to another
(B) like pearls moving mysteriously from one necklace to another
(C) as pearls do that move mysteriously from one necklace to others
(D) like pearls do that move mysteriously from one necklace to others
(E) as do pearls that move mysteriously from one necklace to some other one

Even though it seems as if we are comparing the "jumping" of pearls and genes, we are actually comparing the nouns that have the ability to do the same action.
To compare actions, you would have to mention 'DO'
'as pearls do' would be correct if you wanted to use 'as'

Originally published in 1950, Some Tame Gazelle was Barbara Pym’s first novel, but it does not read like an apprentice work.

Both "like an expert" and "as an expert does" are correct.

"Like" is used to compare "Nouns".
"As" is used to compare "Clauses".

We can say:

1. Tony plays like Robin. ( Comparing Tony(Noun) with Robin(Noun))
2. Tony plays as Robin does. (Comparing the way Tony plays with the way Robin plays)

In this SC, choice is between A and C.

A is not correct even though it has "as an expert does" construction to compare the way an expert reasons with the way computers can reason, because later portion of the sentence is not parallel:

"computers that will be used to diagnose equipment breakdowns, deciding whether to authorize a loan, or other purposes such as these"

C is correct because "like an expert" construction is used to compare a computer to an expert. Moreover, the later portion of the sentence is also parallel.

like an expert-computers that will be used for such purposes as diagnosing equipment breakdowns or deciding whether to authorize a loan.


So C is correct.

Do you have an explanation to this one??? For the previous ones it seems that when we face X CAN do Y like Z we should be on alert??? But this one drops out from this 'thought out' rule.

Sorry fellas! A non-underlined portion of the original sentence is, itself incorrect (see bold). 'Computers' can 'recognize objects' not 'recognizes objects'. Unfortunately, I got stuck right there so didn't even pay attention to the underlined part :(
