Springwater is---clean, since it has been filtered through permeable rocks, but all spring water contains some dissolved minerals.
A, generally fair
B, generally fairly
C, in general fair
D, general and fair

The answer is B. This time I really don't get it.

'Fair' can be used an adverb, right? and What's wrong with 'in general'? While 'generally' is working here, why 'in general' ain't? Is that mean 'fair' should be replaced by 'fairly' in choice C?

So, what's difference between 'fair' and 'fairly'?
"fair" is an adjective; "fairly" is an adverb. To modify an adjective ("clean") an adverb is required, not an adjective. The only choice which would place an adverb in front of the adjective "clean" is choice B.

As far as I know, 'fair' can be used as an adverb too. For example, 'You must play fair.' 'Fair' here means 'in a proper or legal manner'.

But I suppose 'fair' cannot means rather, or distinctly which 'fairly' means. So 'fair' cannot replace 'fairly' here.

hehe Do I get it right? Thank you CJ. You reminded me of that.
So 'fair' cannot replace 'fairly' here.
