Teacher, is this sentence correct?
Her parents say her present anxiety was caused by the accident that happened last November.
The anxiety is current, I'd use "is."
A more natural sentence might be: Her parents say her anxiety started after her accident last November.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
