Artificial intelligence emerged during the late 1950's as an academic discipline based on the assumption that computers are able to be programmed to think like people.
(A) are able to be programmed to think like people
(B) were able to be programmed to think as people
(C) can be programmed to think as people can
(D) could be programmed to think like people
(E) are capable of being programmed to think like people do

i confused between C and D... "comp could be programmed to think" is a clause ..then how can we use like..?
ans D

Artificial intelligence emerged during the late 1950's as an academic discipline based on the assumption that computers are able to be programmed to think like people.
(A) are able to be programmed to think like people
(B) were able to be programmed to think as people
(C) can be programmed to think as people can
(D) could be programmed to think like people
(E) are capable of being programmed to think like people do

The sentence is stating a fact that happened in past. Accordingly the verb should be all in past tense unless there is sequencing of events required. This eliminates A. [spoiler]B & E[/spoiler] are eliminated because of like/as mismatch. Between [spoiler]C & D, C[/spoiler] can be eliminated as there is no main verb for the auxiliary 'can' following 'people'.

Thanks

The word 'like' in answer choice D isn't a problem here. It means 'similar to', which fits the intended meaning of the sentence. Robots would eventually be able to develop thought structures SIMILAR TO those of a human being.

sahil's notes uses this example to distinguish between can and could

could is applicable here because it shows prabability, can is something which is usually used in stems such as:

can i go out ?

"People" is Compared with "computers" not with "programmed to think" So Like is fine. Also if you carefully read option C it says "compute can be programmed to think as people can be programmed to think"
This itself help to eliminate b,c, E and then A is out for tense error.
IMO D

[EducationAisle]

The only way C can be grammatically written is:

Artificial intelligence emerged during the late 1950's as an academic discipline based on the assumption that computers are can be programmed to think as people can (be programmed to think).

People can be programmed to think? - This is clearly absurd. Hence, C is not the answer.

One definition of the preposition like is in the manner characteristic of.
In D, computers could be programmed to think like people means that computers could be programmed to think in the manner characteristic of people.

if you are confused between c & d , you can compare it with"like" and "as" usage.

Like is used to compare nouns
As is used to compare verbs


that implies d is the perfect answer.

[GMATMadeEasy]

Between "can" and "could" , which tense is correct ?

[bubbliiiiiiii]

Between "can" and "could" , which tense is correct ?

Could is more appropriate in this case because we are dealing iwth assumptions. An assumption can properly take could. If it would hace taked can then we are somehow confirming the assumption which is inappropriate.

Experts opinion please.

Between "can" and "could" , which tense is correct ?

[nightcrawler]
