Question:

　　Miss ABC ,

　　I'm glad to talk with u.I want to give u a question which disturbs me. when someone said "Is ice cold?" to me ,does it mean "of course" or "certainly"? By the way,could I express it with "Is sea blue" or "Is ball circinal"etc.Thanks.

　　BEST WISHES

　　Answer:

　　"Is ice cold?" means "of course" but you'd better not to use others.

　　Yours abc
