"The seventh butterfly is beautiful."

Translation: Al șaptelea fluture este frumos.

The miltiple choice is always overly easy, as one can simply look for whichever two sentences are most alike. Having only one acceptable answer more often woild be more useful.

I agree, sometimes I find myself not even reading the phrases and just finding a totally unfitting word which makes me go "nope", but then I feel I didn't practice in my mind the phrase building. Granted, it is something I could force myself to do, but I have to take extra time and effort to do so, which I guess is what language learning requires anyways.
