I got this from 20 Q requester
The HIT is accepted regardless of whether or not you get the questions correct -- so don't worry about that. The questions can definitely be tricky, in part due to the fact that we ask people to play the game with some less common words due to the subject we're researching.
Some of the subjects are definitely a bit more unusual -- we only ask that people do their best to ask questions that try and find out what the subject is and to provide correct answers to the questions. If people are a bit off because a subject is occasionally strange than that's ok.
Thanks again for your help completing these HITs!
