The sentence that contains a **compound subject** is: **"The Senate and the House of Representatives are part of the legislative branch."** ### Explanation: - **Compound Subject:** This occurs when two or more subjects are joined by a conjunction (like "and" or "or") and share the same verb. Let's break down each sentence: 1. **"The Senate and the House of Representatives are part of the legislative branch."** - **Compound Subject:** "The Senate and the House of Representatives" are two distinct entities joined by "and" sharing the verb "are." 2. **"The Supreme Court, which makes decisions about laws, is part of the judicial branch."** - **Single Subject:** "The Supreme Court" is the main subject. The clause "which makes decisions about laws" is a descriptive addition, not part of the compound subject. 3. **"The three branches of the U.S. government are legislative, executive, and judicial."** - **Single Subject:** "The three branches of the U.S. government" is a plural subject, but it's a single entity consisting of three parts, not a compound subject. 4. **"The executive branch includes the president, the vice president, and the president's cabinet."** - **Single Subject:** "The executive branch" is the singular subject. The list that follows describes what it includes, but doesn't form a compound subject. ### Summary: Only the **first sentence** has a compound subject because it directly connects two separate subjects with "and." **Answer:** The first sentence contains a compound subject: “The Senate and the House of Representatives are part of the legislative branch.”
