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

Complicated structure.

Research has shown that L (when speaking...people do), and that M (they will gesture...).

Within "that L" there's another structure. "individuals who N (have been blind) and P (have never seen) nonetheless make hand motions Q (just as frequently) and R (in the same... people do)"

So you've got three pairs of "and" phrases or clauses, in which each part of the pair should be parallel.

So, L and M = pair #1, N and P = pair #2, Q and R = pair #3.

They're all correctly parallel in choice A.
B breaks parallelism for L and M (no "that" before M), as well as breaking some other rules
C breaks parallelism for L and M (no "that" before M), as well as breaking some other rules
D breaks parallelism for N and P (individuals who N and "they" P - I shouldn't repeat the subject here b/c "individuals" is outside of the parallel part of the sentence)
E same as D and B/C

Other rules are broken as well in the wrong ones, but you can use this one rule, parallelism, to deal with all 4 wrong choices.

Hi There,

Unlike the buildings in Mesopotamian cities, which were arranged haphazardly, the same basic plan was followed for all cities of the Indus Valley: with houses laid out on a north-south, east-west grid, and houses and walls were built of standard-size bricks.

Error Analysis

1. â€śUnlikeâ€ť tells us that this sentence presents a contrast. What follows â€śUnlikeâ€ť is â€śthe buildings in Mesopotamian citiesâ€ť. Now, the â€śbuildingsâ€ť have been illogically contrasted with â€śthe same basic planâ€ť that is subject of the main clause. Hence, this sentence has parallelism error. We need to make both the contrasting entities parallel to make the contrast logical.

POE:

Choice A: the buildings in Mesopotamian cities, which were arranged haphazardly, the same basic plan was followed for all cities of the Indus Valley: with houses: Incorrect for the reason stated above.

Choice B: the buildings in Mesopotamian cities, which were haphazard in arrangement, the same basic plan was used in all cities of the Indus Valley: houses were: Incorrect as it repeats the parallelism error of Choice A.

Choice C: the arrangement of buildings in Mesopotamian cities, which were haphazard, the cities of the Indus Valley all followed the same basic plan: houses: Incorrect as it contrasts â€śthe arrangement of buildingsâ€¦â€ť with â€śthe cities of the Indus Valleyâ€ť. We again have illogical contrast here.

Choice D: Mesopotamian cities, in which buildings were arranged haphazardly, the cities of the Indus Valley all followed the same basic plan: houses were: Correct. â€śMesopotamian citiesâ€ť have been correctly contrasted with â€śthe cities of the Indus Valleyâ€ť.

Choice E: Mesopotamian cities, which had buildings that were arranged haphazardly, the same basic plan was used for all cities in the Indus Valley: houses that were: Incorrect. â€śMesopotamian citiesâ€ť have been illogically contrasted with â€śthat same basic planâ€ť.

1. The sentence must present logical comparison or contrast.
2. The entities compared or contrasted must grammatically as well as logically parallel.

Hope this helps.
Thanks.

Hi,

Like the grassy fields and old pastures that the upland sandpiper needs for feeding and nesting when it returns in May after wintering in the Argentine Pampas, the sandpipers vanishing in the northeastern United States is a result of residential and industrial development and of changes in farming practices.

The sentence says that the reasons for the disappearance of grassy fields and old pastures and sandpipers in the northeastern US are the same â€“ residential and industrial development and changes in farming practices. By the way, the upland sandpipers need the grassy fields and old pastures for nesting and breeding when they return in May after spending winter in the Argentine Pampas.

Error Analysis

1. Presence of â€śLikeâ€ť tells us that there is a comparison here. The meaning tells us that the sentence compares the vanishing of grassy fields and old pastures with that of sandpipers. Now, â€śLikeâ€ť is followed by â€śgrassy fields and old pasturesâ€ť that have been illogically compared with â€śthe sandpipers vanishingâ€ť. Since â€śgrassy fields and old pasturesâ€ť are in the non-underlined portion of the sentence, we need â€śsandpipersâ€ť or â€śthe birdâ€ť as the subject of the main clause to make the comparison logical.
2. The sentence uses the phrase â€śsandpipers vanishingâ€ť. Notice that there is no apostrophe after sandpipers. Hence, â€śsandpipersâ€ť is a plural noun now and â€śvanishingâ€ť is the modifier that modifies â€śsandpipersâ€ť. Now plural â€śsandpipersâ€ť does not agree in number with singular verb â€śisâ€ť.

POE:

Choice A: the sandpipers vanishing in the northeastern United States is a result of residential and industrial development and of changes in: Incorrect for the reasons stated above.

Choice B: the bird itself is vanishing in the northeastern United States as a result of residential and industrial development and of changes in: Correct. â€śthe birdâ€ť has now been correctly compared with â€śthe grassy fields and old pasturesâ€ť.

Choice C: that the birds themselves are vanishing in the northeastern United States is due to residential and industrial development and changes to: Incorrect. 1. Use of â€śthatâ€ť is incorrect. 2. The phrase â€śchanges to farming practicesâ€ť is awkward.

Choice D: in the northeastern United States, sandpipersâ€™ vanishing due to residential and industrial development and to changes in: Incorrect. 1. The modifier â€śin the northeastern USâ€ť should not be at the beginning of the main clause. 2. The comparison is now illogically between the â€śthe grassy fields and old pasturesâ€ť and â€śsandpipersâ€™ vanishingâ€ť. 3. There is no verb for â€śsandpipersâ€™ vanishingâ€ť. So we have a fragment and not a main clause. 4. We donâ€™t need â€śtoâ€ť before â€śchanges inâ€¦â€ť.

Choice E: in the northeastern United States, the sandpipersâ€™ vanishing, a result of residential and industrial development and changing: Incorrect. 1. Same modifier error as in Choice D. 2. Same fragment error as in Choice D.

1. The entities compared in the sentence must be grammatically as well as logically parallel.
2. We must have a subject and a verb to form a clause. Absence of any one makes the sentence a fragment.

Hope this helps.
Thanks.

Hi,

By developing the Secure Digital Music Initiative, the recording industry associations of North America, Japan, and Europe hope to create a standardized way of distributing songs and full-length recordings on the Internet that will protect copyright holders and foil the many audio pirates who copy and distribute digital music illegally.

By developing the Secure Digital Music Initiative, the recording industry associations of North America, Japan, and Europe hope to create a standardized way of distributing songs and full-length recordings on the Internet. This standardized way will do two things:
a. it will protect copyright holders, and
b. it will foil the many audio pirates who copy and distribute digital music illegally.

Error Analysis

1. All the subject-verb pairs agree in number and make sense with each other â€“ â€śthatâ€ť (refers to standardized way) and â€świllâ€ť, â€śwhoâ€ť (refers to audio pirates) and â€ścopy and distributeâ€ť.
2. All the modifiers are placed correctly. PS â€“ Relative pronoun â€śthatâ€ť correctly cannot modify the immediate preceding noun â€śInternetâ€ť because we have a very big noun phrase here that has two prepositional phrases â€śa standardized way of distributing songs and full-length recordings on the Internetâ€ť. The way â€śof distributing songs and full-length recordingsâ€ť is giving extra information about the â€śa standardized wayâ€ť and cannot be placed elsewhere in the sentence, same goes with the prepositional phrase â€śon the Internetâ€ť. Since the head of this long noun phrase is â€śa standardized wayâ€ť, the relative pronoun â€śthatâ€ť correctly refers to it. Here we have case of a noun modifier that is placed a little far away from the entity it modifies. This usage is correct.
3. The verb tenses are correct. Simple future â€świll protect and (will) foilâ€ť have been used for the events that will took place in the future while â€ścopy and distributeâ€ť have been correctly written in the simple present tense as they denote general facts.
4. The entities â€świll protectâ€ť and â€ś(will) foilâ€ť are parallel. So are â€ścopyâ€ť and â€śdistributeâ€ť.
5. There are no pronoun and idiom errors in this sentence.
6. The sentence is correct as is.

POE

Choice A: of distributing songs and full-length recordings on the Internet that will protect copyright holders and foil the many audio pirates who copy and distribute: Correct for the reasons stated above.

Choice B: of distributing songs and full-length recordings on the Internet and to protect copyright holders and foiling the many audio pirates copying and distributing: Incorrect. 1. â€śAndâ€ť introduces a new list that distorts the intended meaning of the sentence and that does not have parallel entities.

Choice C: for distributing songs and full-length recordings on the Internet while it protects copyright holders and foils the many audio pirates who copy and distribute: Incorrect. 1. â€śa standardized way forâ€ť is not a correct idiom. 2. Use of simple present tense verbs â€śprotectsâ€ť and â€śfoilsâ€ť for the action that will take place in future is incorrect.

Choice D: to distribute songs and full-length recordings on the Internet while they will protect copyright holders and foil the many audio pirates copying and distributing: Incorrect. The only logical plural referent for pronoun â€śtheyâ€ť is â€śthe recording industry associationsâ€ť. However, they will not do the actions of protecting and foiling. The standardized way will do these actions. This choice changes the meaning of the sentence.

Choice E: to distribute songs and full-length recordings on the Internet and it will protect copyright holders and foiling the many audio pirates who copy and distribute: Incorrect. â€śAndâ€ť introduces a new list that distorts the intended meaning of the sentence and that does not have parallel entities.

1. A list must contain logically and grammatically parallel entities.
2. Correct verb tenses should be used to communicate the intended meaning of the sentence.
3. Pronouns must have logical antecedents and they must agree in number with their antecedents.
4. Be wary of choices that change the intended meaning of the sentence.

Hope this helps.
Thanks.

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 â€“ â€śwho (refers to individuals) with â€śhave never seenâ€ť, â€śindividualsâ€ť with â€śmakeâ€ť, â€śpeopleâ€ť with â€śdoâ€ť and â€śtheyâ€ť with â€świllâ€ť.
2. All the verbs are written in correct tenses.
3. Pronoun â€śtheyâ€ť correctly refers to â€śindividualsâ€ť.
4. All the modifiers are placed correctly and they modify the correct entities.
5. Entities â€śwho have blindâ€¦â€ť and â€śwho thus have never seenâ€ť are parallel. So are entities â€śindividualsâ€¦ make hand motionsâ€ť and â€śsighted people doâ€ť. So are â€śthat individualsâ€¦â€ť and â€śthat they will gestureâ€¦â€ť.
6. The sentence use correct idiom â€ś X as abc as Yâ€ť.
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 gestureâ€ť Incorrect. 1. â€śwho have been blindâ€ť and â€śwho thus never sawâ€ť 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 â€śfrequentâ€ť cannot modify verb â€śmakeâ€ť. 4. Again, use of past tense â€śdidâ€ť 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 â€śmadeâ€ť is incorrect because the sentence is stating a general fact in the present context. 2. Use of â€śas well asâ€ť introduces a new list per which â€śmadeâ€ť and â€śgesturingâ€ť should be parallel but they are not. 3. Also â€śas well asâ€ť violates the parallelism between â€śthat individualsâ€¦â€ť and â€śthat theyâ€¦â€ť.

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 â€śhaving seenâ€ť violates parallelism. 2. Also, this is the wrong tense to use in the context. 3. Use of past tense â€śmadeâ€ť is incorrect. 3. Adjective â€śfrequentâ€ť cannot modify verb â€śmakeâ€ť. 4. Again, use of past tense â€śdidâ€ť 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 â€śas well asâ€ť 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 â€śhaving seenâ€ť as in Choice D. 2. Use of â€śtoâ€ť between subject â€śindividualsâ€ť and verb â€śmakeâ€ť is incorrect. 3. â€śto gestureâ€ť is not parallel to â€śthat individualsâ€¦â€ť.

Hope this helps.
Thanks

In A, is 'sandpipers vanishing' not a gerund? and if yes, it can be parallel to 'grassy fields and old pastures'.

Hi Sachin,

In A, â€śsandpipers vanishingâ€ť is not a gerund. â€śVanishingâ€ť is a verb-ing modifier that presents a characteristic of sandpipers that they are vanishing. Use of â€śvanishingâ€ť is incorrect here. It has been used to function as a gerund but it is not functioning as one.

â€śSandpipersâ€ť is parallel to â€śgrassy fieldsâ€¦â€ť but again we have the SV number agreement as well as make sense issue. Look at the structure here:

â€¦, the sandpipers vanishing in the northeastern United Statesis a result of residential and industrial development and of changes in farming practices.

Here it does not make sense to say that â€śsandpipersâ€ť is a result of residentialâ€¦ Hence, this choice is incorrect.

Hope this helps.
Thanks.

Thanks a lot for your reply, but I have the following doubt.
I believe that vanishing might have acted as a verb-ing modifier had there been no verb 'is' in the sentence..

the sandpipers vanishing in the northeastern
United States is a result

Also, instead of sandpipers vanishing, if we had the vanishing of sandpipers, will this act as a gerund?

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 â€“ â€śwho (refers to individuals) with â€śhave never seenâ€ť, â€śindividualsâ€ť with â€śmakeâ€ť, â€śpeopleâ€ť with â€śdoâ€ť and â€śtheyâ€ť with â€świllâ€ť.
2. All the verbs are written in correct tenses.
3. Pronoun â€śtheyâ€ť correctly refers to â€śindividualsâ€ť.
4. All the modifiers are placed correctly and they modify the correct entities.
5. Entities â€śwho have blindâ€¦â€ť and â€śwho thus have never seenâ€ť are parallel. So are entities â€śindividualsâ€¦ make hand motionsâ€ť and â€śsighted people doâ€ť. So are â€śthat individualsâ€¦â€ť and â€śthat they will gestureâ€¦â€ť.
6. The sentence use correct idiom â€ś X as abc as Yâ€ť.
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 gestureâ€ť Incorrect. 1. â€śwho have been blindâ€ť and â€śwho thus never sawâ€ť 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 â€śfrequentâ€ť cannot modify verb â€śmakeâ€ť. 4. Again, use of past tense â€śdidâ€ť 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 â€śmadeâ€ť is incorrect because the sentence is stating a general fact in the present context. 2. Use of â€śas well asâ€ť introduces a new list per which â€śmadeâ€ť and â€śgesturingâ€ť should be parallel but they are not. 3. Also â€śas well asâ€ť violates the parallelism between â€śthat individualsâ€¦â€ť and â€śthat theyâ€¦â€ť.

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 â€śhaving seenâ€ť violates parallelism. 2. Also, this is the wrong tense to use in the context. 3. Use of past tense â€śmadeâ€ť is incorrect. 3. Adjective â€śfrequentâ€ť cannot modify verb â€śmakeâ€ť. 4. Again, use of past tense â€śdidâ€ť 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 â€śas well asâ€ť 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 â€śhaving seenâ€ť as in Choice D. 2. Use of â€śtoâ€ť between subject â€śindividualsâ€ť and verb â€śmakeâ€ť is incorrect. 3. â€śto gestureâ€ť is not parallel to â€śthat individualsâ€¦â€ť.

Hope this helps.
Thanks

Had there been 'gestured' instead of gesturing, it would have become parallel to 'made' and the sentence would have been right?
In this case do we still need a parallelism with 'that'?

Regards,
Sachin

Hi Sachin,
We do need "that" to maintian parallelism in this sentence. This is because the reserachers found two things:
a. blind people make hand motions as frequently and in almost the same way as sighted people do.
b. blind people gesture even when they converse with another blind person.

These two facts need to be parallel and hence must the second entity must be preceded by "that" because the first entity is preceded by "that".

Hope this helps.
Thanks.

This is amazing..
One key takeaway that I have found from your videos is that you need to split the sentence into clauses.. Extremely thankful for your free videos
You guys rock!!
