First, complete the worksheet.

Task: Identify whether the following sentences are Simple (S), Compound (C), or Complex (CX).

#### Definitions:
1. Simple Sentence: A sentence with only one independent clause (a subject and a predicate).
2. Compound Sentence: A sentence with two or more independent clauses joined by coordinating conjunctions (e.g., "and," "but," "or," "so," etc.) or semicolons.
3. Complex Sentence: A sentence with one independent clause and at least one dependent clause. Dependent clauses cannot stand alone as complete sentences and often begin with subordinating conjunctions (e.g., "because," "although," "since," "if," etc.).

#### 9. Since soccer is Mason’s favorite sport, yet it’s the sport he most excels at.
