According to some experts, carbon dioxide is accumulating in the atmosphere so rapidly, largely because of the burning of fossil fuels, that should the present rate of buildup continue, the global concentration of this poison will double by the end of the next century.

(A) that should the present rate of buildup continue, the global concentration of this poison
(B) should the present rate of buildup continue, the global concentration of this poison
(C) should the present rate of buildup be continued, the global concentration of this poison
(D) the global concentration of this poison, were the present rate of buildup continue,
(E) that the global concentration of this poison, if the present rate of buildup did continue

imo:A

Idiom : So rapidly..that

Cant use Band C because , you need a period before should. Also it doesnt show continuity.
D and E are out as the construction is absurd

thanks

Agree with OA.

The idiom construction has to be so X that Y
Only A and E fit.
E does not qualify because of the erroneous reversal in construction.
i.e present rate of buildup... should precede the global concentration... and not the other way round.

I picked (A).

'so... that' is the idiom

It is easy to narrow down to A and E because idiom so.. that

remove the part after rapidly for better understading.

Now sentence is saying should x happen, y will occur.

In E rate of buildup did continue is wrong.

CRAMYA,

One more reason for rejecting E .

See the If clause ... It has "if the present rate of buildup did continue " .
But non-underlined part has Will .For having Will we must have Simple Present Tense verb in if clause but it is not there .

This is my way of interpritation. Correct me if I am wrong.

Thanks,
Hota :)
