"Siân and Dewi Lingo were shot in France."

Translation: Gafodd Siân a Dewi Lingo eu saethu yn Ffrainc.

What a horrible sentence... I wonder if it was written before the events in Paris.

It was written many months ago, possibly before the attacks in Paris. We deleted it quite soon after the course was released since it is clearly an insensitive sentence. I've just tried the unit on the website and the android and iOS apps and it doesn't appear there.

Can you tell me what you were using to access the course when it came up.

[Martaklon]

I access the course from my laptop using Mozilla.
I was only doing the tests, because I'm quite advanced in Welsh. Perhaps you checked just the lessons in this unit while the sentence somehow remained in the test?

Yes, that's very likely. Hopefully Duolingo will update everything soon.
