"Ты знаешь новую книгу этого автора?"

Translation: Do you know this author's new book?

[Diki_Veliki]

,,Do you know the new book from that author?" not accepted... почему?

[zebby.mann]

Flag it, im pretty sure it should be accepted

[Hatul_Madan]

Do you know the new books of this author'? И это "correct solution"?

[AnastasiaStyIes]

No, because it's only one new book.

[geneven]

Do you know a new book of this author was also rejected

[Hatul_Madan]

Однако именно такой ответ система предлагает в качестве правильного.

[AnastasiaStyIes]

Странный. В таком случае, мы должны использовать "Report a problem" > "The 'Correct solution' is unnatural or has an error".

[Hatul_Madan]

Репорт конечно же отправлен. Как правило, репорты игнорируются, чаще обращают внимание на активность в теме. Ещё одна особенность ошибок в этом, так называемом, "correct solution" - апостроф в конце предложения после author'.

[errant1]

Why is it "this author" but not "that author"? Is there a difference in form?

[BenYoung84]

Yes, strip of the э and you get the "that" form.

[eykao1]

Do you kniw this new book's author? ---It wasn't accepted, but is it correct?

[BenYoung84]

Ignoring the spelling mistake, it would still be wrong because you've reversed the possession, you would have to do the same in the Russian sentence.
