Why don't they accept, "Are you scared?"
Report. That should have been accepted!
Still not accepted on April 2015. Reported.
"scared" and "afraid" can both be used as adjectives,
If someone or something is scared, they are afraid of someone or something. I'm scared of monsters. http://simple.wiktionary.org/wiki/scared
I'll report it.
Would "Você tem medo" also work? If it does, would be considered more or less formal vs. "Você está com medo?"
"Você está com medo" is used more often.
