1. The correct sentence is B. The sea calmed, but no boats left shore.

2. The run-on sentence is B. Karen's uncle arrives tomorrow she wants to see him.

1. That's correct! Option B is the correctly punctuated sentence. The comma is used before the coordinating conjunction "but" to separate two independent clauses, indicating a pause in the sentence.

To determine the correct answer, it's important to understand the rules of punctuation when using coordinating conjunctions like "but." In this case, we have two main clauses ("The sea calmed" and "no boats left shore") that are joined by the coordinating conjunction "but". When coordinating conjunctions join two independent clauses, a comma should be used before the conjunction.

2. That's incorrect. Option B is not a run-on sentence.

A run-on sentence is a type of sentence in which two or more independent clauses are joined without appropriate punctuation or conjunctions. They are typically considered grammatical errors.

In Option B, "Karen's uncle arrives tomorrow, she wants to see him," a comma is used to separate the independent clauses and indicates the break between them. Therefore, it is not a run-on sentence.

To identify run-on sentences, you should look for two independent clauses that are not properly separated (either by conjunctions like "and" or "but" or appropriate punctuation like a comma or a period) or joined by a non-coordinating conjunction (e.g. "however," "therefore").
