1. Which word is used incorrectly in the following sentence? He received an oral dose initially, followed by an IV drip.

• A. received
• B. dose
• C. initial
• D. followed

Correct answer: C

Rationale: The word 'initial' is used incorrectly in the sentence. The correct word that should be used here is 'initially.' 'Initially' is an adverb that is used to indicate the beginning or starting point of an action, while 'initial' is an adjective that describes something as happening at the beginning of a process. In this context, the correct usage would be 'He received an oral dose initially, followed by an IV drip.' The other choices ('received,' 'dose,' and 'followed') are used correctly in the sentence and do not need any corrections.

2. Ocean waves build during a storm until there is a vertical distance from the high point to the low point of 6 meters and a horizontal distance of 9 meters between adjacent crests. The waves hit the shore every 5 seconds. What is the speed of the waves?

• A. 1.2 m/s
• B. 1.8 m/s
• C. 2.0 m/s
• D. 2.4 m/s

Correct answer: B

Rationale: To find the speed of the waves, we use the formula: speed = wavelength / period. The wavelength is the horizontal distance between adjacent crests, which is 9 meters in this case. The period is the time it takes for one wave to pass a fixed point, given as 5 seconds. Therefore, speed = 9 meters / 5 seconds = 1.8 m/s. Choice A (1.2 m/s) is incorrect because it miscalculates the speed. Choice C (2.0 m/s) and Choice D (2.4 m/s) are incorrect as they do not correctly calculate the speed using the provided data.

3. Why was the roadway so dangerous to build?

• A. There weren't enough materials available to build the road
• B. The workers might get hit by passing cars
• C. The men would fall to their deaths
• D. The men would be attacked by animals.

Correct answer: C

Rationale: The roadway was dangerous to build because the men involved in the construction were at risk of falling to their deaths. The excerpt mentions that the construction of the roadway was the most dangerous and treacherous part of the entire task, indicating a high risk of falling due to the height and precarious nature of the construction site. Choice A is incorrect because the danger was due to the physical risks of falling and not due to a lack of materials. Choice B is incorrect as passing cars were not the primary danger during the construction of the roadway. Choice D is incorrect since there is no mention of workers being attacked by animals during the construction of the Golden Gate Bridge.

4. Which vitamin is essential for the clotting of blood?

• A. Vitamin A
• B. Vitamin K
• C. Vitamin C
• D. Vitamin D

Correct answer: B

Rationale: Vitamin K is essential for the synthesis of proteins required for blood clotting. It specifically assists in the activation of clotting factors to prevent excessive bleeding from injuries. Vitamin K plays a crucial role in maintaining a balance between clotting and bleeding in the body. Choices A, C, and D are incorrect. Vitamin A is important for vision, immune function, and skin health. Vitamin C is essential for collagen synthesis and acts as an antioxidant. Vitamin D is crucial for calcium absorption and bone health.

5. In the time required to serve 43 customers, a server breaks 2 glasses and slips 5 times. The next day, the same server breaks 10 glasses. How many customers did she serve?

• A. 25
• B. 43
• C. 86
• D. 215

Correct answer: C

Rationale: In the first scenario, for 43 customers served, the server broke 2 glasses and slipped 5 times. This means for each customer served, the server broke 2/43 glasses and slipped 5/43 times. The information about breaking 10 glasses the next day is irrelevant to the number of customers served. Therefore, to find out the total number of customers served, we calculate 43 customers * (2 glasses/customer + 5 slips/customer) = 86. Choice A, 25, is incorrect as it does not consider the total number of glasses broken or slips. Choice B, 43, is incorrect because it only considers the initial number of customers. Choice D, 215, is incorrect as it miscalculates the relationship between customers, glasses broken, and slips.
