"别担心！不严重。"

Translation: Don't worry! It is not serious.

[Harley497499]

Apparently "It's" is a typo and should be "It is" according to Duolingo. 奇怪的绿鸟!

[Elijah.Fung]

Don't be worried, it's not serious. 这样行吗

[Esther515354]

'Not serious' was marked wrong. Why do we have to add the word 'it's ', when it does not say 这个不严重

[Gabrielle145359]

Chinese and English have different rules. Omitting "it's" sounds like broken English to me.

I put "It isn't serious." and Duolingo said I had a typo! ("is not" = "isn't")
