I will report! The constuction requires an object of some sort.
I was given the sentence in English and thought this was someone having written "that" in stead of "what" .... that would have made sence. So I tried "o que" in Portuguese. Oh, no :)
This is the worst translation ever. I cannot say whether the Portuguese is correct or not but the English translation is completely wrong. The final verb "liked" requires a direct object. I would suggest you add the word "it".
