That question first and foremost tests English reading abilities. Many mathematically gifted non-native speakers (and indeed native speakers) would miss-understand the "different".
For a fair comparison, the translator would have to fully appreciate the relevant connotation of every significant word like "different" in every question, and successfully convey the same in Russian. You couldn't just go to a regular translation service and get a good result.
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.
