- B. To emphasize specific words or phrases in the text.
- C. To connect ideas smoothly and guide the reader's flow.
- D. To introduce opposing viewpoints and counterarguments.

2. What is the difference between constructive and destructive interference of waves?
- A. They have the same effect on wave amplitude.
- B. Constructive interference increases amplitude, while destructive interference decreases it.
- C. They only affect light waves, not sound waves.
- D. They depend on wave speed, not amplitude.
Correct answer: B
Rationale: Constructive interference occurs when peaks of two waves overlap, resulting in a higher combined amplitude. Destructive interference happens when peaks and troughs overlap, cancelling each other out and reducing the overall amplitude.
3. Identify the antonym of the word "pensive":
- A. joyous
- B. thoughtful
- C. curious
- D. introspective
Correct answer: A
Rationale: "Joyous" is the opposite of "pensive," which means thoughtful and slightly melancholy.

- A. Pushing against a wall without moving it
- B. Carrying a heavy object without lifting it
- C. Lifting a box to place it on a shelf
- D. Holding a book stationary in your hand

5. Which of the following is the main function of the pancreas?
- A. To store food and break it down into smaller pieces
- B. To absorb nutrients into the bloodstream
- C. To produce enzymes that help digest food
- D. To regulate blood sugar levels
Correct answer: C
Rationale: Rationale: The pancreas is a vital organ in the digestive system that produces digestive enzymes such as amylase, lipase, and proteases. These enzymes are released into the small intestine to help break down carbohydrates, fats, and proteins in food, aiding in the digestion and absorption of nutrients. Options A and B are incorrect because the pancreas is not involved in storing or absorbing nutrients. Option D is partially correct as the pancreas also plays a role in regulating blood sugar levels by producing insulin and glucagon, but its primary function is to produce digestive enzymes.
6. What is the function of the epiglottis?
- A. Produces saliva
- B. Senses taste
- C. Prevents food from entering the windpipe
- D. Filters blood
Correct answer: C
Rationale: Rationale: The epiglottis is a flap of cartilage located at the base of the tongue that covers the opening of the windpipe (trachea) during swallowing to prevent food and liquids from entering the airway. This action ensures that food and liquids are directed to the esophagus and down into the stomach, rather than entering the respiratory system, which could lead to choking or aspiration pneumonia. The other options (A) Produces saliva, (B) Senses taste, and (D) Filters blood are functions of other structures in the body and are not related to the role of the epiglottis.
