"بِخَيْر اَلْحَمْدُ لِله وَكَيْف عائِلَتِك؟"
Translation:Well, praise be to God. And how is your family?
"Praise be to God" is not really idiomatic English, and it makes answering these questions really difficult, because they expect me to say something that I would not say in everyday life. I have an idea: could we have, in the "report" dialogue (that is, the list you get when you press the "report" button) an option saying "the supposedly correct answer is written in unacceptably bad English"?
