The science of economics, which for four decades was dominated by Keyn

A- main subject "science of economics" lacking the verb.
B - economics -- was (Subject - Verb issue) also main subject "science of economics" lacking verb
C - science of econmics been .. incorrect.. lacking the main verb.

between D and E

both are passive voice

Rewrite in Active voice
D - Keynesians have dominated the science of economics for four decades
E - Keynesians dominated the science of economics, for four decades

D looks perfect here.. present continuous makes sense.

Will go with D.

+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.

*****************************************************

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.

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

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

(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

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.

I have read the posts that say why D is a better choice then E.
I am still unclear as to why we have to use a present progressive tense over a past tense?
More importantly how do I infer the tense from this question?

generis jennpt

how do we know that Keyn's domination IS STILL prevalent?

Predicate is missing in A, B, C. Modifier wrongly placed in E.
