1. Select the meaning of the word in the sentence: 'The dog developed bilateral weakness in its hindquarters.'

A. Present on two sides
B. Available for exercise
C. Affecting the left side
D. Affecting the right side

Correct answer: A

Rationale: "Bilateral" refers to something that affects or involves both sides of the body, making "Present on two sides" the correct answer. The other options refer to one-sided or unrelated conditions.

2. What does the term elasticity mean, as used in the passage about Hypertension?

A. Firmness.
B. Compactness.
C. Flexibility.
D. Rigidity.

Correct answer: C

Rationale: Elasticity, as used in the passage about Hypertension, refers to the stretchiness or flexibility of blood vessels. The text mentions that blood vessels lose elasticity and stiffen as a person ages, indicating that they become less flexible. This eliminates choices A and D (Firmness and Rigidity) as the correct answers. Choice B (Compactness) is unrelated to the concept of elasticity in the context of blood vessels and is therefore incorrect. Understanding elasticity as the ability to stretch or flex helps in choosing flexibility as the correct answer.

3. How many liters are there in 500 milliliters?

A. 0.5 liters
B. 5 liters
C. 50 liters
D. 500,000 liters

Correct answer: A

Rationale: The correct answer is A: 0.5 liters. To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 500 milliliters is equal to 0.5 liters. Choice B, 5 liters, is incorrect because it would be the equivalent of 5000 milliliters. Choice C, 50 liters, is incorrect as it is ten times the converted value. Choice D, 500,000 liters, is way off as it is a thousand times more than the correct conversion.

4. 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.

5. A train leaves the station at 1:45 PM traveling at a constant speed of 65 mph. If it arrives at its destination at 3:15 PM, how many miles did it travel?

A. 97.5 miles
B. 100 miles
C. 95 miles
D. 105 miles

Correct answer: A

Rationale: To calculate the distance traveled by the train, multiply the speed (65 mph) by the time it took to reach the destination, which is 1.5 hours (3:15 PM - 1:45 PM = 1.5 hours). Therefore, 65 mph × 1.5 hours = 97.5 miles. This calculation is correct because distance = speed × time. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the given information.
