The example of a run-on sentence is:
"His favorite instrument to play was the guitar his mother, on the other hand, enjoyed playing the flute."
This sentence is a run-on because it improperly combines two independent clauses without the appropriate punctuation or conjunction. Independent clauses are complete thoughts that can stand alone as sentences. In this case, the clauses "His favorite instrument to play was the guitar" and "his mother, on the other hand, enjoyed playing the flute" are not connected properly, leading to confusion.
To correct this run-on sentence, you can use a semicolon, a period, or a conjunction:
- Using a semicolon: "His favorite instrument to play was the guitar; his mother, on the other hand, enjoyed playing the flute."
- Using a period: "His favorite instrument to play was the guitar. His mother, on the other hand, enjoyed playing the flute."
- Using a conjunction: "His favorite instrument to play was the guitar, but his mother, on the other hand, enjoyed playing the flute."
The other sentences provided do not contain these kinds of errors and are correctly structured.
