Supposing, there is a sentence:
For example, if parents ask their son or daughter: “There are 10 ballerinas at the theater but all of female dancers have gone on the tour. How many ballerinas remained at the theater?”, a child will respond expectedly: “I do not know”.
There are two colons, which, I think, is not an idea to get away with. Could you, please, suggest proper punctuation here?
