Researchers have found that individuals who have been blind from birth

Hi,

Researchers have found that individuals who have been blind from birth, and who thus have never seen anyone gesture, nevertheless make hand motions when speaking just as frequently and in virtually the same way as sighted people do, and that they will gesture even when conversing with another blind person.



Error Analysis

1. All the subjects and verbs make sense and agree in number with each other – “who (refers to individuals) with “have never seen”, “individuals” with “make”, “people” with “do” and “they” with “will”.
2. All the verbs are written in correct tenses.
3. Pronoun “they” correctly refers to “individuals”.
4. All the modifiers are placed correctly and they modify the correct entities.
5. Entities “who have blind…” and “who thus have never seen” are parallel. So are entities “individuals… make hand motions” and “sighted people do”. So are “that individuals…” and “that they will gesture…”.
6. The sentence use correct idiom “ X as abc as Y”.
7. This sentence is correct as is.

POE:

Choice A: who thus have never seen anyone gesture, nevertheless make hand motions when speaking just as frequently and in virtually the same way as sighted people do, and that they will gesture: Correct for the reasons stated above.

Choice B: who thus never saw anyone gesturing, nevertheless make hand motions when speaking just as frequent and in virtually the same way as sighted people did, and that they will gesture” Incorrect. 1. “who have been blind” and “who thus never saw” are not parallel. 2. From verb tense point also, use of past tense to talk about an action that is still performed by blind people is incorrect. 3. Adjective “frequent” cannot modify verb “make”. 4. Again, use of past tense “did” to talk about the general fact that is true of the present content is incorrect.

Choice C: who thus have never seen anyone gesture, nevertheless made hand motions when speaking just as frequently and in virtually the same way as sighted people do, as well as gesturing: Incorrect. 1. Use of past tense “made” is incorrect because the sentence is stating a general fact in the present context. 2. Use of “as well as” introduces a new list per which “made” and “gesturing” should be parallel but they are not. 3. Also “as well as” violates the parallelism between “that individuals…” and “that they…”.

Choice D: thus never having seen anyone gesture, nevertheless made hand motions when speaking just as frequent and in virtually the same way as sighted people did, as well as gesturing: Incorrect. 1. Use of “having seen” violates parallelism. 2. Also, this is the wrong tense to use in the context. 3. Use of past tense “made” is incorrect. 3. Adjective “frequent” cannot modify verb “make”. 4. Again, use of past tense “did” to talk about the general fact that is true of the present content is incorrect. 5. This choice repeats the errors of the use of “as well as” as in choice C.

Choice E: thus never having seen anyone gesture, nevertheless to make hand motions when
speaking just as frequently and in virtually the same way as sighted people do, and to gesture: Incorrect. 1. This choice repeats the errors of the use of “having seen” as in Choice D. 2. Use of “to” between subject “individuals” and verb “make” is incorrect. 3. “to gesture” is not parallel to “that individuals…”.

Hope this helps.
