Answer:
d) do not use correct punctuation to separate the sentences.
Step-by-step explanation:
The reason run-on sentences are grammatically incorrect is because they:
- The absence of punctuation
- combining two or more separate clauses into one.
- They do not indicate when the reader should take a breath.
For example:
Run-on:
My dog is drooling eating and putting her toy in the food bowl and my dog will go to the park today.
Correct grammar:
My dog is drooling, eating, and putting her toy in the food bowl. My dog will go to the park today.
