The conversation between human and AI assistant.
[|Human|] Explain why the given sentence is a run-on sentence.
[|AI|] The given sentence is a run-on sentence because it consists of two independent clauses, "She went to the store" and "she needed supplies", improperly joined without a proper conjunction or punctuation mark to separate them. As it is written, the sentence can be confusing to read and interpret. A correct way to write the sentence would be to separate the independent clauses with a period or semicolon, or to use a conjunction such as "because" or "and" to connect the two: "She went to the store. She needed supplies." or "She went to the store because she needed supplies." or "She went to the store; she needed supplies."
