Is "the thick sugary fluid is carefully separated from the malt husks, and it is called wort." a run on sentence?

A RUN-ON SENTENCE (sometimes called a "fused sentence") has at least two parts, either one of which can stand by itself (in other words, two independent clauses), but the two parts have been smooshed together instead of being properly connected. Review, also, the section which describes Things That Can Happen Between Two Independent Clauses.  

Here is an example  "I love to write papers I would write one every day if I had the time!" The run on sentence would be... "I love to write papers.  I would write one every day if I had the time!"

Hope this helps!!

the answer should be

the simple past tense of strive.

hope this !
