"How many white togas are in the shop?"
Translation:Quot togae candidae sunt in taberna?
Perhaps to encourage, mistakes such as using the incorrect declension, and togas candidas is a mistake, are allowed to pass with a note that says 'typos.' It should just be called and counted as incorrect, but DL is a computer / bot, so exactly what gets counted as a typo and as incorrect can be an adventure. As this is the beta version, you can click on 'My answer was incorrect' to alert them to the glitch.
