1. Identify the sentence with a misplaced modifier.

• A. The child found a dollar walking to school
• B. Walking to school, the child found a dollar
• C. The teacher found a note after class
• D. After class, the teacher found a note

Correct answer: A

Rationale: The correct answer is A because the phrase 'walking to school' seems to modify 'a dollar,' which is illogical. The intended meaning is that the child found the dollar while walking to school. In sentence B, the modifier is correctly placed at the beginning of the sentence, indicating that the child found the dollar while walking to school. Choices C and D do not contain any misplaced modifiers.

2. What is the coefficient of O after the following equation is balanced?

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: A

Rationale: In a balanced chemical equation, the coefficient of oxygen (O) in O2 is already 2, so there is no need to adjust its coefficient further. Therefore, the coefficient of O remains as 1. Since the coefficient of O2 is 2, each O atom is represented by the coefficient of 1, and it does not change during the balancing process. Choices B, C, and D are incorrect as they suggest changing the coefficient of oxygen, which is not necessary for O2 in a balanced equation.

3. What condition might result from a lack of vitamin C?

• A. Kwashiorkor
• B. Pellagra
• C. Rickets
• D. Scurvy

Correct answer: D

Rationale: Scurvy is the correct answer. Scurvy is a condition caused by a deficiency of vitamin C in the diet. Vitamin C is essential for collagen synthesis, and its deficiency leads to symptoms such as weakness, swollen and bleeding gums, joint pain, fatigue, and easy bruising. If left untreated, scurvy can lead to more severe complications. Choices A, B, and C are incorrect. Kwashiorkor is a severe form of malnutrition due to insufficient protein intake, pellagra is caused by a deficiency of niacin (vitamin B3), and rickets results from a deficiency of vitamin D, calcium, or phosphate.

4. What is a common finding in a whiplash injury?

• A. Cardiopulmonary issues
• B. Side-to-side spinal curvature
• C. Eventual herniation of discs
• D. Traumatic injury to ligaments

Correct answer: D

Rationale: A common finding in a whiplash injury is a traumatic injury to ligaments. Whiplash occurs due to sudden hyperextension and hyperflexion of the neck, leading to strain or tearing of ligaments in the neck. This can manifest as neck pain, stiffness, and limited range of motion. While other complications like cardiopulmonary problems, side-to-side spinal curvature, or eventual herniation of discs are not typically associated with whiplash injuries.

5. How much paint do you need to paint the interior walls and floor of a rectangular swimming pool with dimensions 8m by 5m and a depth of 2m? (Assume one can of paint covers 10 sq m)

• A. 56 sq m
• B. 72 sq m
• C. 88 sq m
• D. 104 sq m

Correct answer: C

Rationale: To calculate the total area to be painted, find the area of each wall and the floor, sum them up, and subtract the area of the top surface of the pool. The area to be painted is (2*8 + 2*5 + 8*5) = 16 + 10 + 40 = 66 sq m. Since one can of paint covers 10 sq m, divide the total area (66 sq m) by the coverage area per can to determine the number of cans needed. Therefore, you need 88 sq m of paint, which is equivalent to 9 cans of paint. Choice A, B, and D are incorrect as they do not represent the correct calculation of the total area to be painted.
