"The rich English musician is not resting outside, but inside."
Translation:A gazdag angol zenész nem kint pihen, hanem bent.
A gazdag angol zenész nem kint, hanem bent pihen. This is the correct translation. The translation of DL is wrong, because the "hanem / but" part is related to the location and to the verb pihen. The only way such translation would be correct, if both place and verb would be modified: "nem kint pihen, hanem bent (csinál valamit, pl.) dolgozik" - "is not resting outside, but works inside"
Yes, that's why I said, the translation would have been wrong. The word order can change the meaning of the sentence. Your sentence means that the musician rarely rests outside, while the original sentence refers to the present, what's happening now, where he is resting now. So, that's why I used "csak" instead of "hanem" to make your sentence more correct, but your sentence is also right. :)
