I like your grammar post, Boksil.
Could you tell me when and where you learned about indirect questions in English?
Do you know if the Korean language has indirect questions as well? Oh, here's a challenge for you. We learned how change
wh-questions from direct to indirect, but we didn't really get into
yes/no questions. Do you know how to change them too?

Try this one:
Is King Kong a good movie for little kids?
Could you tell me...?
