How one can err..

by hey_thr67 » Thu Jun 07, 2012 9:33 pm
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.

(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
(B) as an expert does, which may be used for purposes such as diagnosing equipment breakdowns or deciding whether to authorize a loan
(C) like an expert--computers that will be used for such purposes as diagnosing equipment breakdowns or deciding whether to authorize a loan
(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
(E) like an expert, to be used to diagnose equipment breakdowns, deciding whether to authorize a loan or not, or the like


OA is C

[spoiler]Although I marked this question right in revision, I got hooked to difference between "like" and "as" and ignored the parallelism error in A.I think no gmat problem should check one type of error. Hence try not stuck with on type of error. When confused with a single type of error. Try to find other types of error also. [/spoiler]

I also feel C is correct but I have one problem in that:

shouldn't it be 'as an expert does' because we not comparing nouns we are comparing actions.

In 'like an expert' -action is compared since 'does' in implicit. Just adding a 'like' does not change the comparison change from 'action' to 'noun'.

Experts, pleaase help.

According to me, the correct usage should be 'as' and not 'like'. 'As' compares the two verbs and 'Like' compares the two Nouns. In this sentence the second part i.e the to reason is already a verb and so you are comparing the ability to reason so 'as' should be used.

From that perspective OA should be a Clear B.

I strongly object on the OA as C>

Experts please help...

Nice and interesting question which starts the debate of Like Vs As again. Let me start with some facts before jumping into the solution for the problem.

We generally use LIKE and AS to make comparisons.

LIKE

The structure of the sentence is usually: VERB + LIKE + NOUN / PRONOUN.
He speaks like a native speaker.
She looks like a supermodel.

AS

The structure of the sentence is usually: AS + SUBJECT + VERB.
Nobody sings as she does.
They went to the party as they were.

LIKE vs. AS

Be careful, in similar sentences that use LIKE and AS, the meanings of each sentence are very different. For example:
As your boss, I must warn you to be careful. (I am your boss.)
Like your boss, I must warn you to be careful. (I am not your boss, but he/she and I have similar attitudes.)


Now, we know the clear cut differences between them. Coming to the solution:

The sentence intends to inform us "like" an expert in a general statement and not "as" in a specific one expert type.
Rewind the above example we discussed earlier
LIKE vs. AS

Be careful, in similar sentences that use LIKE and AS, the meanings of each sentence are very different. For example:
As your boss, I must warn you to be careful. (I am your boss.)
Like your boss, I must warn you to be careful. (I am not your boss, but he/she and I have similar attitudes.)
So eliminate A, B

D & E sentence construction is too wordy, parallelism error and awkward. Hence C is the answer

A and B cannot be eliminated based on the AS, LIKE usage.

Find my reasoning below.

See Manhattan SC 4th Ed Page 127 Like vs As topic.

An excerpt from MGMAT SC
Like is a preposition. This means that LIKE must be followed by nouns, pronouns, or noun phrases. Never put a clause or a prepositional phrase after like! (Remember, a clause contains a working verb, one that can be the main verb in a sentence.) You can correctly use like to compare two nouns.

Consider the following example:
Right: LIKE her brother, Ava aced the test.

Here, like is followed by the noun phrase her brother. The whole phrase Like her brother indicates a comparison between Ava and her brother (two nouns). Note that like can be followed by gerunds (-Ing forms used as nouns): LIKE swimming, skiing is great exercise.

On the other hand, as can be either a preposition (appearing with a noun) or a conjunction (appearing with a clause). You can correctly use as to compare two clauses. Again, however, you cannot use like to compare clauses.

Wrong: LIKE her brother did, Ava aced the test.
Right: AS her brother DID, Ava aced the test.

The words her brother did form a clause (did is a working verb). Therefore, you must use as to make the comparison between the two clauses Ava aced the test and her brother did. Using like to compare clauses is common in speech but always wrong in writing.

According to the GMAT, there is no difference in meaning between Like her brother, Ava aced the test and As her brother did, Ava aced the test. You can compare Ava and her brother directly, or you can compare what they did.
Check the bold parts above. The point is there is no difference between as an expert does and like an expert. When you try to show some similarity without a verb, use like and when using a verb, use as. The real split in this problem is about the usage of such as and parallelism.
Getting defeated is just a temporary notion, giving it up is what makes it permanent.

Be careful, in similar sentences that use LIKE and AS, the meanings of each sentence are very different. For example:
As your boss, I must warn you to be careful. (I am your boss.)
Like your boss, I must warn you to be careful. (I am not your boss, but he/she and I have similar attitudes.)
As your boss, I must warn you to be careful. (I am your boss.) - As here acts as a preposition and not as a conjunction, 'as' as a conjunction is used to compare clauses. Prepositional phrases don't have verbs in them and are not used for comparison. This example and the next sentence posted above cannot be compared. You are stating wrong examples to explain the concept. Use legit sources buddy. Its always better not to use our own examples. Learn from sources, but don't arrive at conclusion with your own reasoning or examples. The problem with this sort of learning is that we won't learn anything and keep on understanding in the wrong manner, which is of no use to anybody. No offence meant :) You can see my older posts, when I was using my own examples to prove something and at the end, I learnt nothing. Use MGMAT SC, search for explanations. For every problem and every concept they have examples. :)

Experts please help...
CAN understand English.., CAN recognize objects, and CAN reason {as an expert does}

We need a noun in place of {..} - drop A/B

Drop D/E - for use of LIKE in place of SUCH AS (E - not, or the like; D - like the diagnosis of equipment)

C remains.

besides other errors, usage of "such as these" in A is also problematic.
(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.
And patanjali do we really need to have this kind of comparison that you have suggested ? Give references.

Instead of comparison, I was indicating about parallelism. IMO "CAN understand English.., CAN recognize objects, and CAN reason {as an expert does}" are three parallel elements of WHAT COMPUTERS CAN DO and therefore, they need to be in parallel forms.
