2. What is the main topic of the passage?

• A. Benefits of bioremediation in cleaning oil spills.
• B. Dangers of microplastics to marine ecosystems.
• C. History of plastic production and its global impact.
• D. Comparison of different waste management strategies.

4. Muscle tissue is responsible for movement. Which type of muscle tissue is found in the heart?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is a specialized type of muscle tissue found in the heart. Unlike skeletal muscle, which is under voluntary control, and smooth muscle, which is found in the walls of internal organs and blood vessels, cardiac muscle is involuntary and responsible for the rhythmic contractions of the heart to pump blood throughout the body. Therefore, cardiac muscle is the specific type of muscle tissue found in the heart, making it the correct choice for this question.
