1. You need to buy cardboard to cover a rectangular box with dimensions 40cm by 30cm by 25cm. Considering only the exterior surfaces (not flaps or openings), how much cardboard do you need (assume one sheet covers 0.5 sq m)?

• A. 0.3 sq m
• B. 0.6 sq m
• C. 1.2 sq m
• D. 1.8 sq m

Correct answer: C

Rationale: Calculate the areas of each side and add them up for the total surface area. Divide by the coverage area per sheet to determine the number of sheets needed.

2. A medication dosage is listed as 1/2 teaspoon. What is the equivalent dosage in milliliters (1 teaspoon = 5ml)?

• A. 1.25ml
• B. 2.5ml
• C. 3.75ml
• D. 5ml

Correct answer: B

Rationale: 2.5ml: Divide the teaspoon dosage (1/2) by the conversion factor (2 teaspoons/5ml).

3. What is the relationship between the frequency and wavelength of a wave?

• A. Inversely proportional
• B. Directly proportional
• C. No relationship
• D. Depend on the medium

Correct answer: a

Rationale: Frequency and wavelength have an inverse relationship - as one increases, the other decreases.

4. Which force causes an object to move in a circular path?

• A. Tension force
• B. Frictional force
• C. Centripetal force
• D. Gravitational force

Correct answer: c

Rationale: Centripetal force is the force that acts towards the center of a circular path, keeping an object in circular motion.

5. The process of a fertilized egg attaching itself to the uterine lining is called:

• A. Ovulation
• B. Implantation
• C. Parturition
• D. Menstruation

Correct answer: B

Rationale: The correct answer is B: Implantation. Implantation is the process where the fertilized egg, known as a zygote, attaches itself to the uterine lining to begin developing into an embryo. Ovulation is the release of an egg from the ovary, not the attachment process. Parturition refers to the process of giving birth, while menstruation is the shedding of the uterine lining if fertilization does not occur. Therefore, in the context of pregnancy, the process described is specifically referred to as implantation.

6. Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?

• A. Limiting high-sodium foods in the diet
• B. Consuming adequate amounts of cranberry juice
• C. Holding urine in the bladder for long periods
• D. Getting regular moderate-intensity exercise

Correct answer: C

Rationale: The correct answer is C: Holding urine in the bladder for long periods. This is not recommended for optimal urinary system health because it can increase the risk of urinary tract infections and bladder problems. It is important to empty the bladder regularly to prevent bacteria from multiplying and causing infections. Limiting high-sodium foods in the diet helps maintain kidney health by reducing the risk of kidney stones and high blood pressure. Consuming cranberry juice can help prevent urinary tract infections due to its antibacterial properties. Regular moderate-intensity exercise promotes overall health, including good circulation to the kidneys and bladder.
