I can't see in to another evaluators mind, but here are some thoughts so you are not left completely in the dark....
Idézet: DieMaster - 2010.04.06. 12:26:09 What song did Led Zeppelin not sing?
Really??????
This could have had the evaluation because things that are not are more difficult than things that are. To put it another way, listing four songs and saying which song did Led Zeppelin sing is better than asking what they didn't sing.
Idézet: PerrinAybarra - 2010.04.06. 12:46:15 The most popular MMORPG that has over 11 million players is?
This is a question whose answer could easily change. Plus, other online games seem to get the the "special knowledge" evaluation. I don't see any spelling errors, so the evaluator may have chosen the spelling error evaluation so you are not penalized from writing another question.
Idézet: Magik - 2010.04.06. 07:57:17 What is the name of the e-mail service provided by Google?
Thunderbird
GMail
Yahoo Mail
AniMail
I don't really see spelling mistakes here and I'm not sure what to guess at the problem. Email and e-mail should both be acceptable. On a minor note, I think the second service is usually written as "Gmail" but that should not be the sole rejection reason. I suggest a resubmit on this question.

Hmm, I just looked up the details of this one and there seems to be a lot of disagreement. I guess the answer depends on what source of information you believe since there are credible sources citing different answers.
