Hello expert,
Is there any grammatical error in B? If not, why rule out it?
The meaning in B is logical too and we don’t know the writer’s intended meaning cuz there is only one sentence and no context.
Need your opinions. Thanks
The meaning conveyed by the (B) version does not make sense.
Here's the complete (B) version.
Even their most ardent champions concede that nothing other than a technical or scientific breakthrough is needed before solar cells can meet the goal of providing one percent of the nation’s energy needs.Notice the sentence is about what the "most ardent champions" concede. The "most ardent champions" are those who most strongly believe in the use of solar cells. So something that they "concede" would be a drawback or issue with the use of solar cells.
So, the sentence is not logical, because "nothing other than a technical or scientific breakthrough is needed" is something positive about the use of solar cells, not a drawback or issue with the use of solar cells.
Also, "
nothing other than a technical or scientific breakthrough is needed before solar cells can meet the goal of providing one percent of the nation’s energy needs," isn't really logical.
It seems to convey that, before solar cells can meet the goal, nothing more is needed, as if perhaps, after solar cells can meet the goal, something other than a technical or scientific breakthrough will be needed.
So, "before" is not the right connector there. The use of "for" would make more sense, as in
nothing other than a technical or scientific breakthrough is needed for solar cells to meet the goal of providing one percent of the nation’s energy needs
