which of the following means expressing someone else's exact word?

a- comma
b- colon
c- semicolon
d- dash

Disagree, colon

The correct answer is d- dash. When you see a dash used in writing, it means that the writer is quoting someone else's exact words or indicating direct speech. To be sure, let me explain the other options as well:

a- comma: A comma is used to separate items in a list, to separate clauses in a sentence, or to indicate a pause.

b- colon: A colon is used to introduce a list, to separate hours and minutes, or to separate a title and subtitle.

c- semicolon: A semicolon is used to join two closely related independent clauses without using a conjunction or to separate items in a list when the items themselves contain commas.

So, in this context, the correct answer is d- dash, as it indicates the expression of someone else's exact words.

c-semicolon
