It is by listening and evaluating the speaker's questions and responses. When the speaker asks a question, he is surely making a point to the audience through his responses. By that kind of communication, the speaker should have given his purpose to the audiences.
Colons are not used to introduce lists.
Colons denote "that is to say" or
"here's what I mean."
They make sentences’ first parts not important
rather the sentence’s second part contains the important information.
Here are
some of the rules you could use for colons:
*Colons are uses upon introducing items.
*Do not use capital letters after a colon except if
it’s a proper noun.
*Do not use colons after a verb or preposition.
*For independent clauses, especially when the second
sentence explains the paragraph’s meaning, the use of colon is preferred.
*After a colon: capitalize the first letter of the
first word if it is a complete quotation.
