is this a run - on sentence? according to a 2008 study, hog farms across five counties in eastern north carolina produce more than fifteen million tons of manure every year, creating a waste management challenge of epic proportions for county officials.
Answer
Brief Explanations:
A run - on sentence incorrectly combines two or more independent clauses without proper punctuation or conjunctions. This sentence has a single independent clause ("Hog farms across five counties in eastern North Carolina produce more than fifteen million tons of manure every year, creating a waste management challenge of epic proportions for county officials") with an introductory phrase ("According to a 2008 study"). It is grammatically correct and not a run - on.
