Question

Which sentence is punctuated correctly?

Theres only one course of action, that is appropriate, we need to leave town
There's only one course of action that is appropriate—we need to leave town.
Theres only one course of action that is appropriate we need to leave town.
There's only one course of action that is appropriate, we need to leave town

Answer 1

The correct one is:

There's only one course of action that is appropriate--we need to leave town.

"Theres" needs an apostrophe; this word is a contraction between "There" and "is." The bottom-most sentence is incorrect because it is missing ending punctuation, a period.
