For and since are typical contenders for perfect tense in a sentence when referred with a "time frame".
For eg. I have been living here for last 3 years.
I have been living here since 10'o clock yesterday.
So, D becomes obvious choice above E.

(A) economics, which for four decades was
(B) economics that was to be
(C) economics, one which has, for four decades, been
(D) economics is one that for four decades has been
(E) economics, for four decades, is one that was

Tricky


the first clause is independent, so only D and E remain as options, E is awkward and also has both the present and past tense in the same sentence, while D rightly uses the present perfect 'has been'

+1 for E

reason -- > the sentence says "but who were ultimately led away from solutions based on government intervention."

That means they do not dominate the science of economics anymore.

A -- > Which points to economics not the study.
B --> Same problem, that points to economics
C and D -- > has been --> has been indicates the continuing acting -- > which suggests the keynisian's still dominate the science of economics, which contradicts the last part of the sentence

E---> on the other hand uses past tense to correct this issue.

please do let us know the OA and OE.

Not really!!! The dominance of Keynesian's science of Economics is still prevalent. Just the idea or a rule that dictated the science changed.

Say,
Science evolved in 1970: Government dominated economy.
1975: Something else(Privatization) dominated economy.
2011: Science of economy is still prevalent, but the idea is privatization centric.

Moreover, a continuous nature of the sentence demands the use of Present Perfect Continuous OR Past perfect Continuous- some tense with progressive nature.

Missing verb is key to answer this question. Others are bunch of subordinate clauses, missing a main clause. Only D and E have a main clause in them. Out of D and E, D is more direct and concise than E which has problem of passive and of dangling modifier "for four decades".

+1 for D.

The non-underlined parts after the underlined portion are just modifiers.

The point is that choices A, B, and C are fragments without a working verb for the subject; D is the correct one because it uses the right tense of the verb ‘has been’, for an event that began four decides ago, and that continues.

The present perfect is strongly indicated by the prepositional phrase ‘for four decades’

Any allusion to Keynesians in the modifier clause started by the pronoun who , should be simply ignored as irrelevant to the main intent of the topic.

E (Incidentally there is a typo and it should be ‘one’ and not ‘on’) is good enough for grammar, but it is not clear what the prepositional modifier ‘for four decades’ is modifying. It wrongly seems to fall on the science rather than domination. Hence, E can be dropped

D remains the preferred choice.

Guys I am still unable to figure out why E is incorrect.
@fluke..how can you say that the idea is still prevalent. Please let me know where am I committing mistake.

Does anyone has the OA for this problem, since obviously nobody knows the right answer?

My approach to the correct answer:

The science of economics, which for four decades was dominated by Keynesian s, who at first stressed the government’s role in stimulating the economy, but who were ultimately led away from solutions based on government intervention.

Error finding: in the original sentence, ",which" introduces a subordinate clause, but main clause "the science of economics" remains incomplete.
So, A is not the answer.


(A) economics, which for four decades was >> reason stated above.
(B) economics that was to be >> "was to be" - wordy
(C) economics, one which has, for four decades, been >> to much unnecessary breakup of sentence.
(D) economics is one that for four decades has been >> Though this sentence has present tense (when remaining sentence has past tense) I chose it because it is clearly conveying the meaning.
(E) economics, for four decades, is one that was >> "is one that was" wordy

My learning:
1. In a sentence we may have different tenses, but they have to be in different clauses.
2. Too much break up of sentence is unnecessary.

I prefer D.

There is a agreement between subject and passive voice.

Does D change the meaning? I thought has been is something in the past that Has continued to the present. In A we have past tense, so not current.

Hi Wofford09

I hear your concerns and am too intrigued by the change in tense from simple past "was" to present perfect "has been" in the correct answer choice D. I thought "had been" would be more perfect because in the original sentence the simple past "was" was used, so it would be more appropriate if we stick with the same tense whether it be simple past, past perfect, past continuous or any other form of past tenses. But the main clause has simple present "is," so the subordinate clauses' tense cannot be past perfect.

And I also noticed that the other two adjectival clauses modifying the Keynesians have simple past and they are not distorting any time frame in this SC. So, I think this SC doesn't really care about the time expressed in the main clause as well as in the complement clause.

The Keynesians remain the dominant school of thought. Therefore any past tense option can be eliminated - A, E
Of B, C, and D, D is the only answer that contains a main verb (is)

(A) economics, which for four decades was
--> lack of main verb.
(B) economics that was to be
--> lack of main verb.
(C) economics, one which has, for four decades, been
--> lack of main verb.
(D) economics is one that for four decades has been
--> correct.
(E) economics, for four decades, is one that was

Wanted to clarify a few things.
1. is the 'which' is refering to 'the science of economics'
so in A, which modifies the phrase 'the science of economics' right? I do not understand why option A is wrong
Please help to advise. Thanks

We need a verb for the subject "Science of Economics"
A and B goes off.
In C 'one which' is redundant; we would prefer either one or which not both.
C goes off.
The meaning is that Keynesians dominated science of economics for 4 decades.
So we need a present perfect tense.
Moreover in E, 'Science of Economics for 4 decades is the one...' conveys the wrong meaning.
D is grammatically correct and conveys the intended meaning.
