i'm not exactly sure what is intended by "classic/classics" here. in american english there are classics/oldies, like popular music from the last 20-50 years or so, and then there is classical music, like bach, beethoven, tchaikovsky, etc. my response of "do you like classical" was rejected
your response was likely rejected because "classical" is an adjective, and "класику" is a noun in the accusative case. when reading this sentence, i understood it to be "the classics", as in the works of ancient Greek and Latin writers and philosophers. the translation provided is poor English, in any case.
