I have been going over the JLPT test from 1999 and came across this problem that stumped me. For those planning to take the previous tests as practice you may want to avoid this question.
優勝戦{ゆうしょうせん}は、意外{いがい}に_____勝負{しょうぶ}が決まった。
A あっけなく B そっけなく C はかなく D ものたりなく
The correct answer is A, あっけなく, but I'm not 100 percent sure why this is a better choice than ものたりなく. Even the other two look like acceptable choices to me.
In the end, after looking up all the definitions, I picked A because of the 意外{いがい}に, which suggests that the 優勝戦{ゆうしょうせん} was expected to not be so simply decided. But when I thought about it more, D also seems like a suitable answer because I would expect the championship game to be interesting as much as non-trivial.
I concluded that D was not correct only because I could find many examples of it being used, but I'm afraid I'm still missing some of the nuance behind the correct answer.
For any interested further in my logic, I did this problem on my stream where I go over all the answers and look up examples, recorded at http://www.youtube.com/watch?v=KnmEiRkck3s&feature=channel_video_title from 6'30" and continued at: http://www.youtube.com/watch?v=ShOpaZ9iOmw&feature=channel_video_title
