"A che ora chiudete?"

Translation: At what time do you close?

[ann.b.torrey]

I got nailed for translating it as What time do you close? instead of "At what time..." Really?

[PazKe]

I am reporting it because we do not use the 'at' in common spoken English.

[Flysalot]

I have reported it too

[Catia9]

Same here! DL appears to disagree with us... 22/9/14

LOL and here it is FOUR YEARS LATER and it hasn't been fixed. Reporting it although honestly I don't know why.

[ChristineB702527]

What time do you close is perfectly acceptable. Too inflexible, Duolingo!

[GoodLordigans]

I think "shut" is an acceptable synonym for "close".

[kikischlosberg1]

In English we do not always say "at" what time.

[JeremyWils3]

I used shut instead of close which was wrong. Why?

[Flysalot]

See above but I don't agree. I think shut is the same as close in English

[Arucola]

This (the superfluous use of "at") was reported in 2014. Yet four years later, nothing has changed. I guess it's true that with AI there is truly nobody home.

[roselaw]

Exactly. Reporting it yet again.
