ILL MARK BRAINLIST !! Softball was once an Olympic sport, it was a way to showcase the talent of athletes.

run-on  (but technically, it is a comma splice -- but that answer option is not provided)

Explanation:

There are two independent clauses here. Two independent clauses must never be connected with a comma -- unless you add a coordinating conjunction. Alternatively, you may use a period with a capital letter, or you may use a semi-colon with a lower-case letter.

examples:

Softball was once an Olympic sport, and it was a way to showcase the talent of athletes.

Softball was once an Olympic sport. It was a way to showcase the talent of athletes.

Softball was once an Olympic sport; it was a way to showcase the talent of athletes.

A true run-on sentence would be this:

Softball was once an Olympic sport it was a way to showcase the talent of athletes.

Note that there is NO punctuation between clauses.
