Answer:
Mason wants to do well on his next essay he makes an appointment with the ILC writing Center.
Step-by-step explanation:
"Mason wants to do well on his next essay he makes an appointment with the ILC writing Center." is a run-on sentence because it results from two complete sentences being combined together without any necessary punctuation. In this case, we need a semicolon between essay and he, or a period after essay and capitalize the "h" in he.
