What mark of punctuation might indicate that more information is to come?
a. hyphen
b. period
c. dash
d. exclamation point

C.Dash 
A hyphen is used to connect two words together and the exclamation and period are used to end a complete sentence. A dash is used in the middle of a sentence which is where information follows it.

B and D are incorrect because they are punctuation that END sentences

A. hyphen combined words and syllables (long-term, fire-proof)

The answer is C. Dash
is used when you want to add more infromation
