Supreme Court

[GmatKiss]

Although the Supreme Court ruled as long ago as 1880 that Blacks could not be excluded outright from jury service, nearly a century of case-by-case adjudication has been necessary to develop and enforce the principle that all juries must be drawn from "a fair cross section of the community."

(A) has been necessary to develop and enforce the principle that all juries must be
(B) was necessary for developing and enforcing the principle of all juries being
(C) was to be necessary in developing and enforcing the principle of all juries to be
(D) is necessary to develop and enforce the principle that all juries must be
(E) will be necessary for developing and enforcing the principle of all juries being

whats wrong with B?

[cans]

OA A??

[shankar.ashwin]

I think the correct idiom is 'necessary to develop', so that eliminates B,C and E.

D uses present tense.

So, its A IMO

[Calvin123]

IMO A

What is OA?

[dhonu121]

Should be A.
D is gramatically correct but changes the meaning.

[mehrasa]

IMO: A
B is wrong because "it is/was necessary" is a kinda command subjunctive and need to continue with to infinitive or bare form of the verb.. so it is wrong to say' necessary for developing and.....'
