on sentence?

Answer 1

D. These instructions don't help I guess I'll have to call customer support.

Explanation: There's nothing separating the two clauses. If it wasn't a run-on sentence, there would be a conjunction, a semicolon, or a period. There are neither of these things in this sentence, so it is a run-on sentence.

Answer 2

D.

Step-by-step explanation:

The sentence has two phrases that are not seprated by a semicolon, period, or comma.

Phrase One: "These instructions don't help"

Phrase Two: "I guess Ill have to call customer support."
