4. Cartilage, found in joints and the ear, is a type of:

• A. Epithelial tissue
• B. Connective tissue
• C. Muscle tissue
• D. Nervous tissue

Correct answer: B

Rationale: The correct answer is B: Connective tissue. Cartilage is a tough, flexible type of connective tissue that provides support and cushioning in joints and the ear. It is made up of specialized cells called chondrocytes embedded in a gel-like matrix of collagen and proteoglycans. Epithelial tissue (A) covers and lines body surfaces, muscle tissue (C) is responsible for movement, and nervous tissue (D) transmits signals in the body. In contrast, cartilage primarily serves a structural and protective function, placing it within the category of connective tissue.

5. Where does bile, a substance that helps digest fats, come from?

• A. Stomach
• B. Pancreas
• C. Liver
• D. Gallbladder

Correct answer: C

Rationale: Rationale: Bile is a substance that helps digest fats by emulsifying them, which means breaking down large fat globules into smaller droplets to increase the efficiency of fat digestion by enzymes. The liver produces bile, which is then stored and concentrated in the gallbladder before being released into the small intestine to aid in the digestion and absorption of fats. The stomach (option A) is responsible for the initial digestion of food through the action of gastric juices, but bile is not produced in the stomach. The pancreas (option B) secretes digestive enzymes such as lipase to further break down fats in the small intestine, but it does not produce bile. The gallbladder (option D) stores and concentrates bile produced by the liver but does not actually produce bile itself.

Rationale: The passage acknowledges both the promise and challenges of smart cities, demonstrating a balanced perspective.
