Is Crowdflower trying to pull a fast one with this recent development of double quiz mode or is it a glitch?  One can make a mistake on the first page but won't know WHAT got corrected and WHY, which is imperative if one is to learn how to do the task properly, especially when it isn't a true learning mode like yesteryear.  Then there's the possibility it was an unfair correction that needs to be disputed. Though that almost never happens.  /snark

I want to give them the benefit of the doubt but I'm not sure they've earned that yet.
