I marked B because redirected through looks wrong idiom. Can someone confirm this?

IMO E. Clearly the choices are between B and E. A, C, D are improper sentence constructions in itself.

Now for B, past perfect (had) is not appropriate. There is no past tense later in the sentence to which this event can relate to; instead present perfect (have) is used. So this is incorrect. Possibly "had" could have been correct in case it was written "rivers had originally flowed into ..., but then their course was diverted by..."

That leaves E - which seems to have no flaws.

Re: The Chicago and Calumet Rivers originally flowed into the St. Lawrence [#permalink]
Nice question.

The Chicago and Calumet Rivers, [strike]originally flowing into the St. Lawrence by way of Lake Michigan[/strike], have been redirected through the construction of canals so that the water now empties into the Mississippi by way of the Illinois River.

E it is.

E is my Take as well.

B Rivers had originally flowed into the St. Lawrence by way of Lake Michigan, but they have been redirected by constructing . Had and constructing are spoiling the show

In B 'by constructing' refers back to the rivers which is not the case...E is better

The Chicago and Calumet Rivers originally flowed into the St. Lawrence by way of Lake Michigan, but having been redirected by constructing canals so that the water now empties into the Mississippi by way of the Illinois River.

(A) Rivers originally flowed into the St. Lawrence by way of Lake Michigan, but having been redirected by constructing (-ing modifier is not correct)
(B) Rivers had originally flowed into the St. Lawrence by way of Lake Michigan, but they have been redirected by constructing (past perfect is unnecessary no other past even is mentioned for sequencing )
(C) Rivers, which originally flowed into the St. Lawrence by way of Lake Michigan but have been redirected by the construction of (fragmented sentence first part before but has no verb)
(D) Rivers, originally flowing into the St. Lawrence by way of Lake Michigan, but having been redirected by the construction of (same mistake as A, -ing modifer having bean is 99% wrong)
(E) Rivers, originally flowing into the St. Lawrence by way of Lake Michigan, have been redirected through the construction of (perfect S,ing,verb...)

only E follows correct grammatical construction.

I dont think so.

past perfect can go with present perfect. this case is proved by a sentence in gmatprep" immune to, immune from " and is proved by grammar books. some grammar book say that past perfect can go with past simple and present perfect.

so, B is correct regarding this point .

the only error in B is "constructing canal"

by doing is used to show the method the subject uses to do the action in main clause. there is no reason grammatically to use constructing here.

second, b seem that they have been redirected by canal, not by construction of cannal, which is the intended meaning.

this is from gmatprep. the oa is e.

however, I do not like this question.

in e, following show an action which happen in the same time frame as redirected. I do not think this is logic

though the main action is in present perfect, happening from a point in the past to present, and following happen at the beginning of this period and we can consider that following is used loggically, I feel hard to see the logicness.

a very hard question.

tenses in choice b are right.
"by contructing" mean the agent who redirect is "constructing" . this is not logical. the agent who do redirecting is human being. human agent redirect with method of "contruction"

I redirect through contruction. "I' is agent, "contruction" is method. choice b is wrong in this point

this point is hard and in the test room within 30 minutes , WE hardly realize the error. the non native use logic to find error. the native realize the error immediately

(A) Rivers originally flowed into the St. Lawrence by way of Lake Michigan, but having been redirected by constructing --- There is a fundamental flaw in parallelism in this choice. Two ICs, that are joined by a conjunction such as ‘but' have to be in the same format; here, one is a clause and the other is not complete

(B) Rivers had originally flowed into the St. Lawrence by way of Lake Michigan, but they have been redirected by constructing----- In the hierarchy of tenses, the top is the past perfect, then a past tense and then the present perfect. One cannot jump from past perfect to present perfect without traveling through a past tense. So grammatically wrong

(C) Rivers, which originally flowed into the St. Lawrence by way of Lake Michigan but have been redirected by the construction of -- -- This is a forthright fragment because of the intrusion of relative pronoun ‘which’.

(D) Rivers, originally flowing into the St. Lawrence by way of Lake Michigan, but having been redirected by the construction of --- The first part has no verb - a fragment.

(E) Rivers, originally flowing into the St. Lawrence by way of Lake Michigan, have been redirected through the construction of --- A correct simple sentence with a modifier phrase that modifies the subject of the clause. 2. Is also idiomatically better because of using the preposition ‘through’ to indicate a physical flow of water through the canals -- correct


Thanks for the explanation. I am clear on the explanation, but I have doubt on "originally flowing" which indicates present continuous; I think it should be past form sense. So is it correct E in this sense? I would be glad if you explain my query.

look at choice B
contructing is wrong because doing show a process. we do not want to emphasize a process here, so, construction is better
second thing is that. we need "the" before construction because we refer to a specific construction, not a general construction. constructing cannall in B refer to a general action , and, so , is incorrect

anyone know why constructin in choice B is wrong, pls, share with us. thanks

Dear thangvietnam

B is wrong for the following reason.

Rivers had originally flowed ( past perfect) into the St. Lawrence by way of Lake Michigan, but they have been redirected ( present perfect) by constructing

Grammatical correct sequence is past perfect sentence, then past tense sentence , then present or present perfect sentence.

In this sense B is incorrect.

Pls give me +1 kudos.

Apart from the tenses issue in B, to say rivers have been redirected BY constructing the canals seems improper. It's better to say they have been redirected through the construction canals (E)
Just listen to the meaning of both.

@experts pls correct me if this wrong.

Dear AnthonyRitz GMATGuruNY AjiteshArun IanStewart EducationAisle MartyTargetTestPrep DmitryFarber GMATNinja VeritasPrepHailey,

I'm just curious how V-ING "originally flowing" happened AT THE SAME TIME as the main verb "have been redirected"
My understanding is that "originally flowing" should occur BEFORE those rivers "have been redirected"
