1. Identify the compound-complex sentence in the following options:

• A. The baker decorated the cake, and then he presented it proudly.
• B. Although it was raining, the children played outside.
• C. When the sun rises, the birds begin to sing.
• D. He enjoyed reading the book because it was suspenseful.

Correct answer: D

Rationale: A compound-complex sentence contains at least two independent clauses and at least one dependent clause.

2. What term describes the point where parallel rays of light converge or appear to diverge from after passing through a lens or reflecting off a mirror?

• A. Aperture
• B. Focal length
• C. Refractive index
• D. Lens thickness

Correct answer: B

Rationale: The focal length is the term that describes the point where parallel rays of light converge or appear to diverge from after passing through a lens or reflecting off a mirror. It is a crucial parameter in optics and is used to determine the magnification and image formation in optical systems. The other options (A) Aperture, (C) Refractive index, and (D) Lens thickness are not directly related to the point where parallel rays of light converge or appear to diverge.

3. A rocket engine expels hot gases backwards. What principle explains the rocket's forward motion?

• A. Newton's first law of motion
• B. Newton's second law of motion
• C. Newton's third law of motion
• D. Law of conservation of energy

Correct answer: C

Rationale: The hot gases expelled backwards exert a force on the rocket in the opposite direction (forward), propelling it upwards according to the action-reaction principle.

4. Which of the following is NOT a type of intermolecular force?

• A. Hydrogen bonding
• B. Dipole-dipole interactions
• C. Ionic bonding
• D. London dispersion forces

Correct answer: C

Rationale: Ionic bonding is a type of intramolecular force, holding ions together within an ionic compound. Intermolecular forces are responsible for the interactions between individual molecules.

5. Discern the INCORRECT function of the liver.

• A. Bile production, aiding digestion.
• B. Blood protein synthesis, such as albumin.
• C. Glucose storage for energy regulation.
• D. Filtration of waste products from the blood.

Correct answer: D

Rationale: Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.

6. Which of the following is the main organ responsible for absorbing nutrients?

• A. Stomach
• B. Small intestine
• C. Large intestine
• D. Pancreas

Correct answer: B

Rationale: Rationale: The small intestine is the main organ responsible for absorbing nutrients from the food we eat. It is where the majority of digestion and absorption of nutrients such as carbohydrates, proteins, fats, vitamins, and minerals occurs. The inner lining of the small intestine is covered in tiny finger-like projections called villi, which increase the surface area available for nutrient absorption. The stomach plays a role in breaking down food into smaller particles, but the actual absorption of nutrients primarily takes place in the small intestine. The large intestine mainly absorbs water and electrolytes, while the pancreas produces digestive enzymes and hormones but is not primarily responsible for absorbing nutrients.
