OA : later

IMO A

In my opinion it is C.

I grouped "...with no great seriousness or dedication" together. Because the original sentence had excepting, I figure the sentence needs a word that relates to the word "excepting."

I was split between A, C, D...then I wittled it down to C and D....then I chose C.

C is the best variant here

Please post the OA

C seems right, we need "whether" here. out of A, C & D, C is concise & clear

will go wth C

it should be A

OA: C
