Why is なんて the correct answer for this question?


Here's a question from N3文法スピードマスター。

> 英語も中国語もスペイン語もできる*なんて*、素晴らしいですねえ。

This question is multiple-choice, so the other incorrect choices were:
なんと、など、なんか just for your information.

Here's my question:

According to the book, it says that なんて is used to lighten or diminish the
impact of the subject in question. Using that grammar point, my translation of
the above question would be: Things like being able to do English and Chinese
and Spanish is great.

However, that translation doesn't seem to fit into the grammar point of なんて
being derogatory, so right now I'm quite confused. What's the purpose of なんて
in this question?




Wait, I'm a little confused on the question. The title says "What's the
purpose of なんて?", but it really seems like you're asking "Why is なんて the
correct answer?" Anyway, here's why I think it's the correct answer.

According to [this answer on a similar
question](https://japanese.stackexchange.com/a/1823/78), `なんか` only goes
before verbs, so that would be incorrect. `など` is a more formal/written(?)
form of `なんて`, and this sentence is clearly be spoken in an informal (though
polite) form. `なんと` would emphasize the `素晴らしいですねぇ`, so the preceding would
have to be something like `...できて` or `...できるのは`.
