Doubting that the translation caused some discrepancy isn't unreasonable. Technical and academic works are notoriously difficult to translate, and it's entirely possible that even though "different" was stressed, certain languages lost the distinction, whereas if the word had been "unique" the distinction would have remained.

Although I have no faith in a multiple choice test as a predictor of CS knowledge anyway. That is just a horrible test format anyway.
