• A. Introduce a famous tourist destination.
• B. Explain the architectural style of Petra.
• C. Emphasize the historical context of the city.

2. Which of the following substances is a common base found in household products?

• A. Sodium chloride (NaCl)
• B. Ammonia (NH₃)
• C. Vinegar
• D. Lemon juice

Correct answer: b

Rationale: Ammonia is a common base found in household products. The other choices are acids.

3. What is the relationship between force and acceleration according to Newton's second law?

• A. Force is directly proportional to acceleration
• B. orce is inversely proportional to acceleration
• C. Force has no relation to acceleration
• D. Force causes deceleration, not acceleration

Correct answer: A

Rationale: According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This relationship is mathematically expressed as F = ma, where F represents force, m represents mass, and a represents acceleration. Therefore, an increase in force will result in a proportional increase in acceleration, supporting the statement that force is directly proportional to acceleration.

4. What is the difference between a real image and a virtual image formed by a lens?

• A. Real images can be projected onto a screen, while virtual images cannot.
• B. Real images are always upright, while virtual images can be inverted.
• C. Real images are formed by converging lenses, while virtual images are formed by diverging lenses.
• D. All of the above are true.

Correct answer: A

Rationale: Real images are formed by the actual convergence of light rays and can be projected onto a screen, while virtual images are formed by the apparent divergence of light rays and cannot be projected.

5. Identify the relative clause in the sentence "The book that won the award was a bestseller."

• A. "The book"
• B. "that won the award"
• C. "was a bestseller"
• D. "award"

Correct answer: B

Rationale: The relative clause "that won the award" provides additional information about the specific book.

6. What type of enzyme breaks down carbohydrates like starches and sugars in the mouth?

• A. Pepsin
• B. Lipase
• C. Amylase
• D. Trypsin

Correct answer: C

Rationale: The correct answer is C: Amylase. Amylase is an enzyme specifically responsible for breaking down carbohydrates like starches and sugars in the mouth. It is produced by both the salivary glands and the pancreas. Pepsin (A) is an enzyme that breaks down proteins in the stomach, lipase (B) breaks down fats, and trypsin (D) is another enzyme that digests proteins but is produced in the pancreas and works in the small intestine. Therefore, amylase is the enzyme that targets carbohydrates in the mouth, aiding in the initial digestion process of these nutrients.
