「一番背が高くなります。」 or 「背が一番高くなります。」?


To translate the sentence: "Who became the tallest?", which is more natural?

> 誰が一番背が高くなりましたか。or 誰が背が一番高くなりましたか。

On Busuu (language learning app), the correct option was the former (一番 before
背, rather than before 高く).

Shouldn't 一番 be before the adjective?




As a translation of _the tallest_ , both 背が一番高い and 一番背が高い work fine. For
example:

  * クラスで一番背が高いのは太郎だ
  * クラスで背が一番高いのは太郎だ

are both natural and mean _It is Taro that is the tallest in the class_.

As for the sentences in question, 誰が背が一番高くなりましたか is less idiomatic just
because of the two consecutive が-phrases.
