Question

Which of the following is not a run-on sentence?

A.) The average length for a feature film is between 80 and 100 minutes but there are some films that exceed 14 hours in length and one film that was 85 hours long.

B.) According to data collected throughout film history, the average length for a feature film is between 80 and 100 minutes, although some far exceed the standard running time.

C.) There are some movies that clock in at over 14 hours long even though the average movie is around 80 minutes but can run up to 120 minutes.

D.) With an average film length of 80 to 100 minutes it can be surprising to discover that some movies have been 14 hours long and even 85 hours long.

Answer 1

C.) There are some movies that clock in at over 14 hours long even though the average movie is around 80 minutes but can run up to 120 minutes.

The statement is a little perplexing because it contains several clauses and concepts, but it is not a run-on sentence. It has a dependent clause ("even though the average movie is around 80 minutes") and an independent clause ("There are some movies that clock in at over 14 hours long") that are combined appropriately by a conjunction ("but").

Answer 2

The sentence that is not a run-on sentence is:

According to data collected throughout film history, the average length for a feature film is between 80 and 100 minutes, although some far exceed the standard running time.

This sentence is correctly punctuated, with a comma separating the independent clause "According to data collected throughout film history, the average length for a feature film is between 80 and 100 minutes" from the dependent clause "although some far exceed the standard running time."
