Even I thought it is C, but the "can" at the end of the sentence misled me.

C.can be trained to communicate like humans can.

Does the can mean that the "humans can be trained to communicate"? If so, then it is altering the meaning of the original sentence, because the original sentence probably wants to convey that dolphins can be trained to communicate like how humans can communicate. Not how humans can be trained to communicate..

See the difference..

Thats why I am stuck. what is the OA Please...Is it E?

Why not D?

"could" is incorrect?

oops .. sorry, just now i noticed the "as", obviously they can't communicate "AS" humans

In that case, E is the answer for me.

as humans "do" is the correct one

A case of the use of proper diction and like vs as.

a) are able to be trained to communicate as humans … are able to be is not the preferred diction. Can be or could be is the right ; drop
b) were able to be trained to communicate like humans --- were able to be is still worse uses wrong tense as well as wrong diction; drop
c) can be trained to communicate like humans can …. -[color=#0000ff]Like humans can - is a clause. Like can not be used to compare clauses.

d) could be trained to communicate as humans ---- correct choice. – As - can be used to denote positions.
e) are capable of being trained to communicate as humans do --- are capable of being trained is poor diction.

Comparison can be made between two things:-
1) Dolphins, Like humans, can be trained
2) Dolphins can be trained, as humans can be.

a) are able to be trained to communicate as humans. 'Ability' is compared with 'humans'
b) were able to be trained to communicate like humans 'Ability' is compared with 'humans'
c) can be trained to communicate like humans can 'like' is used to compare actions
d) could be trained to communicate as humans Correct choice
e) are capable of being trained to communicate as humans do Use of being is generally wrong on GMAT

d) could be trained to communicate as humans Correct choice
e) are capable of being trained to communicate as humans do Use of being is generally wrong on GMAT

I think Being in option E is used in the correct form.
Correct uses of Being:
1. As a noun
2. Continuous verb tense. Option E falls in this form

Now that we are talking about the 'possibility' we should use 'could'.

'As' can either be used to compare or highlight the role/responsibility. In the original sentence "dolphins communicate as humans" uses noun and not a clause, option E uses a clause and hence changes the intended meaning as well.

Let me know if in case you find some errors!

A.are able to be trained to communicate as humans .
B.were able to be trained like humans .
C.can be trained to communicate like humans can.
D.Could be trained to communicate as humans .
E.are capable of being trained to communicate as humans do .

A can be eliminated as it doesn't follow the usage rule of AS (As+clause)C can be eliminated as it doesn't follow rule of LIKE (Like + NO CLAUSE -- Or just Like + Noun)
B can be eliminated as it uses wrong tense (simple past) to present a fact.

Seems like I played a wrong strategy here haha.

As is suggesting roles here.. so A & D can't be rejected for this reason.

Digging further, E is wrong as it suggests that humans can be trained? Not right.
A - are able to be trained is not right usage.

So D.

Aren't we comparing the way of communication here?

What I have read is AS + NOUN is correct only when we are telling the role of something. So, as per the meaning of the sentence, it should be dolphins communicate as humans do. But as per the OA marked, it is saying Dolphins communicate and then they play the role of a Human.

I am not clear on this.

As far as I'm concern, [as + noun] is right only when subject of the following clause is that noun. For example,
As a teacher, Mary could assign as many exercises as she wants.
In the above example, Mary is a teacher. But in (D), how can dolphins are humans? Please shed some light. Thank you.

Besides, searching on google, I found out that in other GMAT forums, it is said that OA is (E). I wonder what actual correct answer is??
This debatable question is from Kaplan. Should I neglect further question from this source from now on? I will appreciate your advice on this.

D is absolutely not correct. There's a big difference between "as humans" (meaning "in the role of humans") and "as humans do" (meaning "in the same way as humans"). E is the only viable answer. Don't let the word "being," which often serves as a red flag for awkward constructions, immediately put you off of any answer. There are certainly better ways than E to express the thought (how about "can be trained to communicate"?), but all the other choices are wrong.

If you want a better (official) question about dolphins, try this one. https://gmatclub.com/forum/the-results- ... 24015.html
