Thank you for the opportunity to help you with your question!
A comma splice sentence is also a type of run-on sentence with two independent clauses fused together awkwardly. For example:
"Alfred is a dog, he likes to eat biscuits."
You can fix this problem by adding a period where the comma is and starting a new sentence, adding a semicolon where the comma is and starting a new sentence, or adding a transitional expression like "however" or "moreover".
Therefore, the answer here is all of the above.
