Question

fill in the blank. turn off the light when you leave the room. the conjunction in the middle means _?_. a dash is needed no comma is needed an exclamation point is needed

Explanation:

In English grammar, when a subordinate clause (here, "when you leave the room") follows the main clause ("Turn off the light"), no comma is used. A dash is used for other purposes like indicating a break in thought, and an exclamation point is for strong emotion, which is not relevant here.

Answer:

no comma is needed
