1. What is the absolute value of -7?

• A. 49
• B. 17
• C. 7
• D. 14

Correct answer: A

Rationale: Absolute value refers to the non-negative distance of a number from zero. Regardless of being positive or negative, 7 is its distance from zero.

2. The author's tone towards UBI can be described as

• A. Strongly supportive, advocating for its immediate implementation without reservations.
• B. Strongly critical, highlighting only the potential drawbacks and dismissing its benefits.
• C. Neutral and objective, presenting both sides of the argument without taking a stance.
• D. Cautiously optimistic, acknowledging both the potential and challenges while calling for further discussion.

Correct answer: D

Rationale: The passage acknowledges both positive and negative aspects of UBI, suggesting a cautious and balanced perspective, aligning with D.

3. What is the function of the underlined phrase "with a mischievous grin" in the sentence "He approached her with a mischievous grin, his eyes twinkling"?

• A. Subject
• B. Direct object
• C. Adverbial phrase
• D. Appositive phrase

Correct answer: C

Rationale: The underlined phrase modifies the verb "approached" by describing his manner, making it an adverbial phrase.

4. Which type of wave requires a medium to travel through?

• A. Electromagnetic waves
• B. Mechanical waves
• C. Sound waves
• D. Both a and c

Correct answer: d

Rationale: Both mechanical waves (such as sound waves) and electromagnetic waves (like light) have different requirements for propagation, but both can travel through a medium.

5. What is the acceleration of an object moving at a constant speed of 20 m/s if it comes to a complete stop within 5 seconds?

• A. 0 m/s² (no acceleration)
• B. 4 m/s²
• C. -4 m/s²
• D. Information insufficient

Correct answer: C

Rationale: The acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 0 m/s (as the object comes to a complete stop), the initial velocity is 20 m/s, and the time taken is 5 seconds. Plugging these values into the formula, we get acceleration = (0 m/s - 20 m/s) / 5 s = -20 m/s / 5 s = -4 m/s². Therefore, the acceleration is -4 m/s².

6. A birdbath has a hemispherical bowl with a diameter of 30cm. What is its volume?

• A. 675 cu cm
• B. 1350 cu cm
• C. 2700 cu cm
• D. 4050 cu cm

Correct answer: C

Rationale: Use half the formula for a sphere's volume: (2/3) * π * (radius)^3. Calculate the radius (15cm) and substitute: (2/3) * π * (15cm)^3 ≈ 2700 cu cm.
