"There is an increase of the quantity."
Translation:Υπάρχει αύξηση της ποσότητας.
Funnily, three years after jaye16's comment, I tossed in μία and DL slapped my wrist over the stress mark! "Pay attention to the accents. υπάρχει μια αύξηση της ποσότητας." So this sentence was finally unlocked, but still needs the alternative version of μια added as acceptable.
