SC - Idiom usage and Parallelism

[karthikpandian19]

According to the Alan Turing artificial intelligence test, a computer is considered "intelligent" if a human judge, who is engaged in text-only conversation both with the computer and with another human, cannot distinguish between the computer's responses and from when the human has written a response.


(A) between the computer's responses and from when the human has written a response

(B) the responses of the computer from those written by the human

(C) between computer responses and that which the human wrote

(D) responses of the computer and the human's written responses

(E) computer's responses with the responses that were written by the human

(A) between the computer's responses and from when the human has written a response
(no need to use "from" with "between", and the two types of responses are not parallel)

(B) the responses of the computer from those written by the human
(correct; distinguish *x* from *y* works, and the use of "those" to mean "responses" makes both parts parallel)

(C) between computer responses and that which the human wrote
(should be "those" since "responses" is plural; also uses a conjugated verb instead of the participle "written" (as in B))


(D) responses of the computer and the human's written responses
(distinguish *x* and *y* doesn't work; since we're looking for a contrast between the two types, we need a word that indicates that (as "from" does))

(E) computer's responses with the responses that were written by the human
(same problem as D except "with" instead of "and"; could also simplify the second part of the comparison as B did)

OA is B

[karthikpandian19]

Bill,

One doubt.....btwn B & C

(B) the responses of the computer from those written by the human
(correct; distinguish *x* from *y* works, and the use of "those" to mean "responses" makes both parts parallel)

1. If C is mentioned with "those" instead of "that" will it be correct?

2. In B, we use passive voice

from those written by the human

whereas in C, we use active voice

those which the human wrote

(assuming "those")? which one is preferable.

(C) between computer responses and that which the human wrote
(should be "those" since "responses" is plural; also uses a conjugated verb instead of the participle "written" (as in B))

B is more parallel here, I'd say: "responses of the computer" vs. "those written by the human" It's not really passive voice as "written" is used as a participle to modify "those."
